THE FAMILIES AND GENERA 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. fiir Naturk., 
p. 101. 
Type-species. — Megaloglossus ivoermanni 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 2 ) conspic- 
uously smaller than next succeeding tooth. 
Species examined. — Trygenycteris woermanni (Pagenstecher). 
Remarks. — This genus is unique among the Iviodotine 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. Clieiropteruges Ramsay, Proc. Linn. Soc. New South Wales, II, p. 17, 
July, 1877. 
1899. Melonycteris Matschie, Flederm. des Berliner Mus. fiir 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 
Kiodotus
