THE FAMILIES AND GENEKA OF BATS. 73 



Genus TRYGENYCTERIS Lydekker. 



1885. Megaloglossus Pagenstecher, Zool. Anzeiger, VIII, p. 245, April 27, 



1885. (Not Megaglossa Rondani, 1865.) 

 1891. Trygenycteris Lydekker, in Flower and Lydekker, Mammals living 



and extinct, p. 655. 

 1899. Megaloglossus Matschie, Flederm. des Berliner Mus. fur Nnturk., 



p. 101. 



Type-species. — Megaloglossus woermanni Pagenstecher. 



Geographic distribution. — Western Africa from Liberia to the 

 Kongo. 



Number of forms. — The type species only has been thus far dis- 

 covered. 



Characters. — Like Kiodotus, but skull with occipital region less 

 deflected (alveolar line projected backward, passing noticably below 

 middle of braincase), mandibular symphysis scarcely or not longer 

 than distance between outer edges of canines, incisors equally spaced, 

 the middle upper teeth not projecting forward, the lower with dis- 

 tinctly bifid crowns, and anterior upper premolar (pm-) conspic- 

 uously smaller than next succeeding tooth. 



Species examined. — Trygenycteris woermanni (Pagenstecher). 



Remarks. — This genus is unique among the Kiodotine bats in its 

 perpendicular middle upper incisors and distinctly bifid lower in- 

 cisors. In the shortness of the mandibular symphysis it is ap- 

 proached by Eonycteris only. 



Genus MELONYCTERIS Dobson. 



1877. Melonycteris Dobson, Proc. Zool. Soc. London, p. 119, June, 1877 (see 



Catal. Chiropt. Brit. Mus., p. 97). 

 1877. Cheiropteruges Ramsay, Proc. Linn. Soc. New South Wales, II, p. 17, 



July, 1877. 

 1899. Melonycteris Matschie, Flederm. des Berliner Mus. fur Naturk., p. 92. 



Type-species. — Melonycteris melanops Dobson. 



Geographic distribution. — Southwestern New Guinea and the Bis- 

 marck Archipelago. 



Number of forms. — One ; the type species. 



Character. — Externally like Kiodotus, except that the nostrils are 

 more projecting and the wing is attached to dorsum of foot slightly 

 above base of third toe. (The only known species is not as small as 

 the species of Kiodotus, head and body about 110 mm., and the color 

 of the underparts, head, and face is much darker than that of back.) 

 Skull not essentially different from that of Kiodotus, though larger 

 and more heavily built. Teeth 34 (Plates VII, VIII, fig. 4) as in
