Distance from origin to origin of: pectoral and pelvics 19.2, 20.8; pelvics and 



anal ii.i, 11.2. 

 Trunk, opposite ist dorsal, a little less than V^ as high as the length to origin of 

 caudal, thus more slender than in vulpinus. Caudal peduncle compressed laterally, with- 

 out lateral keels or ridges. A well marked precaudal pit above, but none below. Dermal 

 denticles of two kinds, mostly minute, very widely spaced, lanceolate, but expanded ante- 

 riorly on either side and spinous rather than scale-like, the blades not definitely marked 

 oflF from the pedicels; interspersed among these small denticles are much larger ones, in 

 pairs, the one close behind the other, of shapes more easily illustrated than described 

 (Fig. 26 C).
