Breadth of the disc ahnost equal to the length from the tip 

 of the snout to the end of the ventral fins. Tail, measured 

 from its end to the middle of the vent, 1.03-1.1 in the length 

 from the same point to the tip of the snout. Interocular 

 space subequal to the narrowest interspiracle width, and 1.1- 

 1.2 in the preocular portion of the head. Internasal width 

 2.8-3, and width of mouth 2.04-2.3 in the preoral portion of 

 the head. 



Snout angular, but not produced beyond the margin of the 

 disc. Anterior margins of the pectorals shghtly sinuous or 

 almost straight from the snout to the broadly rounded 

 exterior angles ; postero -lateral margins convex, their junc- 

 tion with the inner margins rounded. 



Eyes of moderate size, their length 2.5-2.7 in the interocular 

 space. Inner margin of spiracle with an obtuse angular pro- 

 jection. Nostrils with large free lobes posteriorly which 

 overhang the angles of the mouth. Internasal valve with a 

 broad free fringe of flattened tentacular processes, which are 

 about fourteen in number on each side ; the postero-extemal
