Delolepis, new genus, Crypfacanihidce. 



Body anguilliform, moderately compressed from the vent backward ; 

 provided with small, cycloid, imbricated scales. 



Vent nearly median ; a small anal papilla. 



Lateral line continuous, nearly straight, slightly above rhe middle of 

 the body in front of the vent, median from vent backward; it consists 

 of a series of open pores withont prominent raised tubes. 



Head oblong, subquadrangular, shallow concave on the vertex, naked, 

 with the muciferous channels well developed. Snout short, obtuse. 

 Nostrils single, tubular, close behind the intermaxillars, in a horizontal 

 line with the middle of the eye. Eyes small, encroaching on the dorsal 

 outline, somewhat more prominent than in Cnjptaccuithodcsj separated 

 by a moderately wide interspace and surrounded by a series of shallow 

 pits. Mouth wide, oblique, terminal, the lower jaw i)rojecting" beyond 

 the upper. 



Lips fieshy. Intermaxillars slightly jirotractile, with two rows of 

 small conical teeth, re-enforced by a few larger ones at the sympliysis 

 behind the inner row. Mandibular teeth uniserial, larger than the 

 intermaxillar, a few additional ones at the symphysis. Vomer and 

 palate armetl with a few moderately large teeth. Tongue smooth, ad- 

 herent. A few shallow x»its in the under surface of the mandible, <;on- 

 tinued in a series on the i)osterior border of the i>reopercidum. Oper- 

 culum unarmed. 



Gill-openings wide, the membranes attached to a narrow istlimus, ex- 

 tending ba(;kward beyond the pe(;toral base, and without a x)r<T.jecting 

 tlaj). Gills four, a wide slit bcliiiid the fourth; gill rakers very short, 

 obtuse, in moderate number. Pseudobranchise.
