This genus is most closely related to Clinocottus from which 

 it differs in the larger spinules on the body, the absence of cirri 

 on the back and at the base of the dorsals, and in having fewer 

 and smaller cirri on the top of the head.

Fig. 2. Eusulus saburrae, type. 



Body short, moderately thick, heaviest at shoukhn's. Profile 

 of head precipitous anteriorly; slightly concave at occiput; lower 

 profile gently curved from chin to ventrals. Lower jaw included ; 

 maxillary reaching to below center of eye; fine villiform teeth on 

 jaws, vomer, and palatines. luterorbital space shallowly con- 

 cave; equal to half diameter of eye. Eye on level with upper 

 margin of head ; its diameter a little less than length of snout. 

 Nasal spines blunt; distance from their tip to mouth a little 

 greater than length of eye. Upper preopercular spine bifid ; its 

 superior spine the shorter, directed upward and backward ; the 

 inferior directed backward and slightly upward; two slight 

 angles on lower edge of preopercle represent the usual lower 

 spines. Head entirely naked and with many large pores behind 

 and below eye. Three or four cirri on the margin of the preoper- 

 culum, and a row behind each eye on top of head.
