do not differ very noticeably from those of Kiodotus. Incisors and 
canines quite as in that genus. Cheek teeth both above and below 
uniformly smaller than in Kiodotus (compared with a Philippine 
specimen of the lagochilus type), a character that is especially notice- 
able in the upper molars, the combined crown length of which (3 
teeth) is scarcely more than in the related genus (2 teeth). Third 
upper molar well developed, nearly as large as m 3 , its crown sub* 
circular in outline. External characters as in Kiodotus. Tongue 
with the papillae smaller than in Kiodotus (compared with Philip- 
pine lagochilus only), those at side and tip (except extreme anterior 
margin) so widely spaced that the surface of the tongue is plainly 
visible between them (in Kiodotus they overlap so that the surface 
of the tongue is quite hidden). 
Species examined. — Odontonycteris meyeri Jentink or a closely 
related species from Cagayan Sulu (north of Sandakan, Borneo). 
Remarks. — While the characters of the single specimen of Odon- 
tonycteris that I have examined (male, ad. Cat. No. 125316, U.S. 
N.M., collected by Dr. Edgar A. Mearns, February 25, 1904), might 
suggest an abnormal Kiodotus , they ar,e too important to permit the 
name to be placed in synonymy. This individual has in the left 
mandible a small supplemental tooth behind the third molar. 
Genus SYCONYCTERIS Matsehie. 
1899. Syconycteris Matschie, Flederm. des Berliner Mus. fur Naturk., p. 98. 
(Subgenus of Macroglossus=Kiodotus.) 
1902. Syconycteris Jentink, Notes from the Leyden Museum, XXIII, No. 3 
(July, 1901), p. 131, July 15, 1902. (Genus.) 
Type-species. — Macroglossus minimus vai*. australis Peters. 
Geographic distribution. — New Guinea, northen Australia, and 
the neighboring islands (Bismarck Archipelago, Aru, Louisiade 
Islands) . 
Number of forms. — Four species are recognized. 
Characters. — Like Kiodotus , but with much larger incisors, the 
height of those in upper jaw greater than width of premaxillaries, 
those in the lower jaw forming a continuous line between canines, 
and all, except the middle, pair below (which are less than half as 
large as outer), approximately equal in diameter to posterior molars 
(m 3 and m 3 ). Occiput not as much deflected as in Kiodotus , the 
alveolar line when projected backward passing distinctly below mid- 
dle of braincase. 
Species examined. — Syconycteris crassa (Thomas). 
Remarks . — As Doctor Jentink has pointed out, this group, origi- 
nally defined as a subgenus of Kiodotus to contain the species austra- 
lis , papuanus , finschi , and crassus , seems quite worthy of recognition 
as a genus.
