59.9(87)Article XII.- MAMMALS FROM THE CAURA DISTRICT OFVENEZUELA, WITH DESCRIPTION OF A NEW SPECIESOF CHROTOPTERUS.BY J. A. ALLEN.A short time since a small but interesting collection of mammals wasreceived from the Caura region of Venezuela, collected for the Museum byMr. M. A. Carriker, Jr., during November and December, 1909. The26 specimens contained in the collection represent 14 species, of which oneproved to be new. All of the larger species are represented by one or morecomplete skeletons.The Museum had previously received, in 1900-1902, a considerablecollection of mammals from the vicinity of Ciudad Bolivar and the LowerCaura collected by Mr. Samuel M. Klages, reported upon by me in VolumeXX of this Bulletin.' Most of the species in the Carriker collection arerepresented in the Klages collection, but from very different localities. Mr.Carriker's collection was made on the Rio Mato, the largest western tributaryof the Rio Caura, and on the Rio Mocho, a tributary of the Rio Mato.The monkeys here recorded have been kindly determined by Dr. D. G.Elliot, who is now monographing the Primates.1. Bradypus tridactylus flaccidus (Gray).One specimen, a very young female apparently in first pelage (totallength 260 mm.), Rio Mato, Nov. 3.The body pelage is dull drab, with the rump whitish, varied elsewherewith small patches of white; face and throat white with a faint tinge offulvous; narrow black eye-stripes. The hair of the facial region is entirelydifferent in structure from that of the body, being fine and bristly. Althoughso young, the dentition is fully developed, except that the teeth are small.145I New Mammals from Venezuela and Columbia. Bull. Amer. Mus. Nat.

[Vol. XXVIII,Represented by 7 specimens (skins and skulls), 2 males and 5 females,all taken on the same day and at the same locality. There is practically novariation in color, except that the younger specimens have the dorsal surfacedarker than the old male type described above.The collector's external measurements of the series are as follows:No. 30181, 6, total length 90; tail, 9; expanse, 356.30178 6, " " 80; " 13; " 332." 30180, Y, " " 99; 9; 343.30179, 9, " " 85; " 14; " 346.30182, 9, " " 82; " 11; " 336.30183, 9, " " 81; " 13; " 351.30177, 9, " " 80; " 12; " 342.Chrotopterus carrikeri is much smaller than C. auritus, and very differentlycolored, but in general structure and proportions, absence of fur on themembranes, the striations on the outer half of the ear, and in the charactersof the skull and teeth it agrees in all essential details with that species.

In the female the 'upper arms andshoulders are fulvous, the whole dorsal area dull dark brown, and the hindlimbs are dark brown with a strong rusty wash. The tail varies from nearlyuniform grizzled yellowish brown to grizzled rufous brown, with the lowerand upper surfaces nearly concolor, but in one the apical half of the lowersurface is yellowish white, and in another there is a subapical area of ful-vous about three inches in length.1491910.]
