Description. About three inches and a quarter in total 

 length, the head constituting the third of it, the caudal fin 

 excluded. The occipital region is depressed, and the inter- 

 ocular region, which is broader than in Artedius lateralis, 

 instead of being convex is groove-like. The rostral dis- 

 tance gently slopes towards the extremity of the snout, 

 exhibiting two stout and conspicuous nasal spines, behind 

 which is a depression for a tubular posterior nostril ; the ante- 

 rior nostril being as usual on the side of the snout nearer 

 the orbit than the extremity of the rostrum. The posterior 

 extremity of the maxillary extending to a vertical line, 

 passing rather posterior to the middle of the pupil. The 

 eye is large, subcircular, situated towards the upper surface 

 of the head ; its horizontal diameter is contained four times 

 in the length of the side of the head: not quite once in 

 advance of the anterior rim of the orbit. A short and flat- 

 tened tricuspid process may be observed upon the con-
