Rypticus arenatus Valenciennes. 



Head 3; depth 3|; D. Ill, 21; A. 14; snout 6 in head, measured 

 from upper jaw tip; eye 4|; maxillary 2|; interorbital 11|; pores 

 in lateral line about 73; rakers x + 8, x, clavate, 3 in eye; eye 

 longer than snout; maxillary extends slightly beyond hind eye 

 edge. Iris dark reddish. Edges of dorsal, caudal and anal very 

 narrowly whitish, submarginal region blackish. One example 5f 

 inches long. 



This species is acknowledged to be distinct from R. sajwnaceus on 

 account of its larger eye, longer than snout. As I have no cor- 

 responding small examples of R. saponaceus, these points cannot be 

 verified. Boulenger says the snout and eye are equal in R. arenatus, 

 though in my example the eye is distinctly larger. Jordan and Rutter 

 have mentioned several examples from Jamaica,^^ and state "one has 

 three opercular spines" and "aside from the number of opercular 

 spines, this species may be distinguished from the preceding by its 

 more slender body, depth 1^ to 1| in head, and by the less projecting 

 lower jaw. " Now the type of Eleutheraciis coriaceus Cope shows the 

 depth greater than the length of the head, and the preopercular spines 

 2 on the left side (lower bifid) of the head and 3 on the right side. 

 The opercular spines are three on both sides, and both upper and 

 median of left side bifid.
