Biological Notes OCULAR ASYMMETRY IN CERTAIN TEXAS IsOPODS.--Van Name, in his 1936 monograph of American land and fresh-water isopods, gives (p. 237) the number of ommatidia ("ocelli") in the species Porcellio (Proporcellio) quadriseriatus Verh. as "about eighteen, well-formed." A careful examination of ten male individuals ( coll. Dallas, Texas, May 15-June· 1, 1932), gave the following results: Individual Number of Ommatidia Left eye Right eye A U 23 B 20 ? C 18 23 D 22 20 E 12 21 F 23 15 G 23 23 H W ~ I 21 20 J 17 23 All of the ommatidia appeared_ to be well developed and well pig-mented; I observed no poorly-developed or -pigmented "ocelli" such as have been reported for various species of Philoscia, Trichorina, and Cubaris. The eyes were examined under conditions that precluded the possibility of miscounting. The query under Individual B is due to the loss of the preparation during the examination.--S. W. Geiser. 1 VITIS MUSTANGENSIS Bµckley var. diversa (L. H. Bailey) Shinners, comb. nov.-V. candicans Engelm. var. dive'l"sa L. H. Bailey, Gentes Herb. 3: 190. 1934. In Plantae Lindheimerianae II (Boston Journ. Nat. Hist. 6): 166, 1850, Gray remarks, "Under the name of V. candicans, (n. sp.,) Engelm. ined., I have from Lindheimer, as also from Mr .. Wright, Texas specimens of.what appears to be a variety of V. Cali-fornica, Benth., with the leaves somewhat less dentate and more densely tomentose beneath." This certainly does not constitute Valid publica-tion of a new species. Rehder is doubly in error in maintaining V. candicans as the correct name, and attributing it to "Engelrn. & Gray" (Bibliog. Cult. Trees & Shrubs, p. 446, 1949). Vitis candican.~ Eng-elm. was not actually published until 1887, by Planchon, in DC .• Mon. Phan. 5: 326, twenty-five years after Buckley had named and described the same species (Proc. Acad. Phila. 13 [1861]: 451, 1862). Gray sharply criticized Buckley for disregarding Engelmann's name, and for using what he thought was an improper adiectival form. implying that a geographic location was referred to (Proc. Acad. Phila. 14 [18621: 162, 1863). Buckley quite justly replied that Engelmann had not really described and published the species, and that the adjectival specific name referre<l not to the animal, but to a stream bearing that name (ibid. 22 [1870]: 136-137, 1870) .--Lloyd H.
