164 Mr. 0. Thomas on Bats from Old Calabar. scarcely rising above the gum. First lower premolar small, but larger than the first upper ; second premolar considerably-larger than the canine in cross section, and nearly equal to it in vertical extent ; third again larger, but with a short external cusp ; first molar less than the last premolar, about three fourths its size, flat-crowned ; second molar much smaller, S3 j rcely more than half its antero-posterior diameter, and vel with the gum. The skull presents no peculiarity ; zygomatic arches well developed, postorbital processes of the frontals short and very acute at their extremities ; no prominent sagittal ridge. Length of an adult, head and body, 3'2 inches, tail 04, head 1*2, eye from tip of nostril 0'4, ear 0*55, forearm 2*3, thumb 0*8, second finger 1*45; third finger — metacarp. 1*55, 1st ph. 1*0, 2nd ph. I'D: fifth linger— metacarp. 1*45, 1st ph. 0*75, 2nd ph. 0*75 ; tibia 1*0, calcaneum 0'2, foot 0*58. Hab. Sarawak, Borneo. The above description has been taken from one of four male specimens preserved in alcohol from the collection of Ward's Museum, Rochester, New York, U. S. A. All agree remark-ably closely in measurements and in other respects. It may be seen from the description that this species is very much smaller than the only other known species of the sub-genus Ptenochirus, namely C. Jagorii, Ptrs., from the Philip-pine Islands, from which it differs also in the form of the extremity of the muzzle and in the relative position and size of the teeth. The specimen from which I have taken the above descrip-tion was kindly forwarded to me by Mr. Frederic A. Lucas, who had correctly recognized it as representing a hitherto undescribed species ; and I have therefore much pleasure in connecting his name with it. XXII. — On Bats from Old Calabar.
