Water temperatures and levels seem important in regulating spawning of, and consequent tubercle development in, Carpiodes species. Females of Cflrpiodes with weU developed ovaries taken during the period of male tubercle development we re apparently not tuberculate. Fowler's (191 2) drawing of the tubercle distribution of C. cutisanserinus agrees fairly well with my observations 'of C. velifer, al-though Fowler did not depict tubercles on the fins or on the body other than on the dorsal ridge. Fowler's drawing of C. dif-formis (= velifer) likely represents a male with only partially developed tubercles. The tubercle distribut.ion on Fowler's C. velifer does no t agree with my observations on C. cyprinus~ and it seems most likely that he depiCled still another specimen of the pres-ent C. ve lifer~ but his drawing does not allow identification of the species. Nuptial tubercle patterns are apparently species specific in Carpiodes. Knowledge of the tubercle distribution on the plains carp-sucker form of C. cyprinus (see Bailey and Allum, 1962) might clarify more fully the status of that fish. The tubercle patterns possibly indicate isolating mechanisms in the spawning behavior of these fi shes.

TENTACULUS WALTAIRIEN SIS RAO AND DUTT, 1965, A JUNIOR SYNONYM OF PHOLIOIDES THOMASENl NIELSEN 1960 (PISCES:HALioPHIDAE). - Nielsen (1960) described the genus Pholioides to ac-commodate P. thomaseni, a new blennioid fish he based on fi ve specimens from rock pools near Karachi, Pakistan. This species, as he remarked, "is the first record of a rep-resentative of the Haliophidae from between the Red Sea and the Philippines," Members of the family, however, have been recorded from Arsu Island, northwest o f Australia, and from the east coasts of Africa and Mada-gascar. Recently R ao and Dutt (1965) described a new genus and species of Haliophidae, T en-taculus waltajriensis, based on one specimen from Waltair, Andhra Pradesh, India and four specimens from Okha, Gujcrat, India, collected from rock pools. T. wallairiensis is identical with Ph olio ides thomaseni and evi-dently the authors were not aware of the earlier description of the fish by Nielsen (1960). According to the rule of priority, Tentaculus becomes a junior synonym of Pholioides and T. waltairiensis becomes a junior synonym o f- P . thomaseni. Between 1962- 1964, I was able to collect 21 specimens of Pholioides thomaseni from Rupan Coast (ten miles south of Okha), Piro tan Island (Gulf of Kutch), and Kiew Point (three miles from Okha), along with several other blennioid fishes, a brief report of which will be published elsewhere. A specimen of P. thomaseni was sent in 1964 to the U. S. National Museum (No. 198209) at the request of Dr. Victor G, Springer. Nielsen (op. cit .), while placing Plwljoides in the family Haliophidae, to which it is most closeJy related, stated that he was doing so with some hesitation because Pholioides differs from the other members of the family in the absence of teeth on the vomer. He felt that this difference might indicate that Phol-ioides represented a separate family. Fur-ther, P. thomaseni and Haliophis malayanus ICHTHYOLOGICAL NOTES 459 M. Weber do not have a differentiated tail, although this character is also indicated by Smith (1952) as one of the diagnostic charac-ters of the family Haliophidae. Hence the definition of the family Haliophidae should be altered to exclude the above characters from the family diagnosis. An examination of my specimens shows that the interorbital cirri for which Rao and Dutt (op. cit.) use the term "tentacle," is not present in all specimens. In the 21 speci-mens I had collected the interorbital cirri are well developed in 12, absent in three; and in varying degrees of development in six. There appears also to be considerable-varia-tion in the vertebral count of the species. While-the prehaemal count of 17 is constant in all specimens examined by Nielsen (op. cit .) and Rao and Dutt (op. cit.), the haemal count is 46 in the holotype, 50 in one para-type, and 49 in the other paratypes. The latter authors give a count of 47 in their specimens. Some color variation has been noticed, reference to which has already been made by these authors. LITERATURE CITED NIELSEN,1- 1960.

TERATOLOGICAL NOTES ON STRIPED BASS (ROCCUS SAXATILIS) OF SAN FRANCISCO BA y'- Anomalous striped bass have been reponed many times, and these anomalies have always been referred to as a malformation of the head termed pug-headedness. A total of at least 22 pugheaded striped bass has been reported to date (Man-sueti, 1960; Dawson, 1964; Alperin, 1965), all from the east coast of the United States. These fish, in extreme cases, have an acutely steep forehead, exophthalmic eyes, pushed-in snout, shortened maxillae and mandible, and are not able to close their mouths completely. Fig. 1. Head of 4 year old (~) striped bass, captured 9 November 1963. 20.5 inches in fork length, weight 4 lb. Left premaxilla and most of maxilla and supramaxilla are absent. Right maxilla and premaxilla are reduced in size and the premaxilla is bulbous-shaped with promi-nent teeth on the anterior surface. Recently, Edward K. Strong, M.D., of San Francisco, Cali!., contributed to the Tiburon Marine Laboratory several anomalous striped bass caught in San Francisco Bay between January 1959 and December 1965. In some specimens only the head was available, but information on date of capture, total weight, fork length. condition, and stomach contents was supplied for each specimen. In addition to the specimens given to the laboratory, Dr. Strong reponed the capture of two typical pugheaded striped bass. One, a 7 lb. speci-men (record size with this affliCtion) caught 30 October 1960, was given to the California Academy of Sciences where it was recorded but is no longer available for study. The other was only 15 inches in length so was returned alive to the Bay because the legal minimum keeping size in California is 16 inches. The fish shown in Fig. 1 illustrates a congenital deformity similar to pugheaded striped bass, but the condition is less severe, the lower jaw and eyes appear normal, and the forehead is less steep .. For lack of a bet-ter term, Dr. Strong called this condition "harelip." One "harelip" specimen captured was under 16 inches in length and was re-leased. A four year old female, 20.5 inches in length and weighing 4 lb., captured on 9 November 1963, has a snout only slightly shorter than nonnal. However, the left maxilla, instead of extending posteriorly along the side of the head to below the eye,
