156 UROSALPTNX. 



imbricated over the plaits ; squama 1 behind the columella valid, 

 raised and canaliculate ; at the sutures, the plaits and lirae obso- 

 lete ; outer lip cremilate outside and toothed within ; columella 

 lip expanded, umbilicus margined with rounded, imbricated 

 scales. Length 27, lat. 15 mill. 



E. Coast Tasmania ; rather uncommon. 



At one time I considered this a Tasmauian var. of T. Hanleyi, 

 Ang. (== Paivae, Cr.), but a comparison of many specimens 

 shows me that the present is an entirely different shell, very 

 much more scabrous. The umbilicus and its margin are also 

 peculiar and distinct. 



The above is the original description. Not figured. 



U. DUBIA, Hutton. 



Oval, fusiform, thick ; whorls of the spire seven, convex, with 

 coarse spiral ribs ; the spiral whorls only furnished with longitu- 

 dinal ribs ; mouth oval ; canal very short. Covered with a per- 

 sistent greenish brown epidermis ; dark purple within the aper- 

 ture. Length *7 inch, lat. *4 inch. 



New Zealand. 



Wider than U. Paivte, the canal much shorter ; distinguished 

 also by the absence of ribs on the body -whorl. Not figured. 



U. PLEBEIA, Hutton. U. BRAZIERI, Woods. U. AUSTRALIA, 



Woods. U. INFERA, Hutton. U. GOLDSTEIN j. Woods. 

 Kobelt includes these in his catalogue of Uroxalpiitx, which he 

 makes a subgenus of Trojjhon. I have described them under 

 Trophon. 



U. TRITONIFORMIS, Bl. PL 39, fig*. 491, 488, 41H>. 



Brownish, the nodules sometimes nearly black ; bluish or pur- 

 plish within, sometimes banded. Length *75 1*25 inches. 



Philippines ; Australia ; Tasmania. 



Readily distinguished by its small size and long, turriculated 

 spire. I have before me a similar form said to come from 

 Ceylon. 



Dunker redescribed this species making for it a new genus, 

 Adamsia typica, and H. and A. Adams have adopted it as a sub- 

 genus of the pisanoid genus Cominella: it is, however, a true
