RelationsMps . — The distinguishing characters of this species are the 

 small number of pectoral rays, the gill slit above the pectoral, and the

Figure 90.— Paraliparis melanobkanchus. Teeth from type 



Body deepest at the nape, tapering into an attenuate tail as in P. 

 cepfialus. Head comparatively heavy; occiput swollen, prominent;

 rays unsegmented. Caudal truncate, connected for one-third its 

 length to the anal. Pectoral notched deeply but not to the base; the
