NEW COTTID FISHES BOLIN 



35 



anal ray 1.2 in third ray, which is longest, being 2.6 in head. Pec- 

 toral base 2.3 in head; fin of 18 rays; longest ray 1.7 in head; fin 

 extending to level of third dorsal ray. Base of pelvics behind lower 

 end of pectorals at a distance about equal to posterior width of 

 maxillary; inner ray the longer, extending about 0.7 distance to 

 anus. Caudal truncate, with 8 split rays, its length 1.6 in head. 

 Anus in front of anal origin at a distance about 2.5 in orbit; located 

 just anterior to the base of a slender, fingerlike, genital papilla, 

 about as long as nasal spine. 



Lateral line armed with 27 delicate, deeply embedded scales, each 

 scale in the form of an incomplete tube, the lateral face open, dorsal 

 and ventral surfaces pierced by several fenestrae. Pores of lateral 

 line occurring in a double series, each pore of the lower series 

 matched by a smaller one directly above it. No scales other than 

 those of lateral line. A single minute cirrus on dorsal part of eye- 

 ball, no others on head or body.
