 smooth, slightly swollen. 



Teeth. Incisors (PI. IX. fig. 10) largest in the genus ; i.' long, 

 slanting nearly horizontally forwards. Canines present and probahly 

 functional to a certain extent, about 3 or 4 millim. long and 1 mil- 

 lim. in diameter, their tips rounded. P.* triangular, rounded, its 

 posterior transverse diameter nearly double its anterior, owing to 

 the large size of the postero-internal talon ; its two main cusps

Type in collection. 



The only difference of importance that I can perceive between 

 Mr. De Yis's description of 0. annulicavda and our specimens of 

 this species is the presence in the former of a " nearly black " 

 inuzzle and of darker face-markings in front of and behind the base 

 of the ear. That these, however, are individual and not specific 

 characteristics is shown by the fact that there is in the Paris 

 Museum a specimen *, also from the Gulf of Carpentaria, which has 

 no trace of them, although it has the same distinct dorsal stripe and 

 comes from the same locality as the type of 0. annulicauda. It 

 should, however, be mentioned, in justice to Mr. De Vis, that, owing 

 to the faded condition of the typical specimen, neither the dorsal 

 stripe nor the candal annulations are shown in Gould's figures of 

 the species, nor is any reference to the latter character made either 

 by that author or by Waterhouse.
