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 lagocMlus 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 papiike 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. 

 KM., collected by Dr. Edgar A. Mearns, February 25, 1904) , might 

 suggest an abnormal Kiodotus, they are 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 Matschie. 



1899. Syconycteris Matschie, Flederm. des Berliner Mus. fiir 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 var. 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 reco<mition 

 as a genus.
