I have not seen the above-named and perhaps doubtful species,

Depth 12 to 21.1 in total length, head 5.75 to 8, and 2 to 2.78 

 in trunk; tail approximately the length of head and trunk or 

 it may be as much as 0.14 longer or shorter; eyes moderately 

 large, 8 to 11.6 in head, and 1.25 to 2 in the short snout, which 

 goes 5 to 7.5 in head ; the large horizontal mouth closes entirely, 

 and is 2.2 to 2.6 in head ; origin of dorsal a little before or over 

 gill openings, which are as wide as or smaller than eyes ; teeth 

 vary much with age; maxillaries with twelve to fourteen short 

 compressed teeth in outer row and one to four much longer 

 depressible canines in an anterior inner row, or with age 

 maxillary teeth reduced to five, six, or eight, with no inner row ; 

 intermaxillary plate with an outer row of eight to sixteen teeth 

 hardly larger, and one to four, usually two or three, depressible 

 mesial canines, the posterior ones much the longest ; occasionally 

 they are lacking; vomerine teeth small and highly variable, from 

 eight or ten in a single row, or five pairs, through all sorts of 

 irregularities to twenty or more partially or completely biserial ; 

 lower jaw with from twelve to twenty teeth on each side, and 

 often with one to three pairs of larger teeth forming inner rows 

 near symphysis. 



Color of living specimens light grayish, everywhere marked 

 with irregular, dendritic, anastomosing purplish to purplish
