1.8 in head; teeth in each jaw in an outer series of rather strong teeth, 

 not extending to angle of mouth, followed anteriorly by a band of 

 small pointed teeth; vomer with a few minute teeth; palatines with 

 a series of somewhat compressed teeth, larger than the lateral teeth 

 in jaws; both lips minutely fringed; a rather long simple (undivided) 

 tentacle, about as long as pupil, behind the very short tube of anterior 

 nostril; tentacle over eye simple, rather smaller than the one behind 

 nostril; dorsal fin beginning about halfway between posterior margin 

 of eye and margin of preopercle, only moderately notched, the spinous 

 part not greatly elevated anteriorly, not bearing membranous flaps, 

 the third to fifth longest, 2.0, 1.8 in head; soft part of dorsal notably 

 shorter than spinous part, its longest rays scarcely shorter than the 

 longest spines; caudal slightly attached by broad membranes to dorsal 

 and anal, rather broadly convex, only about as long as postorbital 

 part of head; anal long and low, without well differentiated spines, 

 its base 2.0, 2.0 in length; ventral moderately long, narrow, the rays 

 not widely separated, nor with broad membranes between them, the

two longest ones distally free, the middle ray longest, about as long 

 as head without snout, 6.2, 5.6 in length; pectoral rather broad, the 

 longest rays in lower half of fin, 1.3, 1.3 in head, 5.5, 5.5 in length. 



Color brownish; back with seven or eight irregular dark cross 

 blotches enclosing some of the lighter ground color; middle of side 

 with about eight irregular dark spots, the next to the last one elongate; 

 sides with many other dark points and lines enclosing more or less 

 definitely diamond-shaped light areas; lower surface of head with 

 four or five dark cross stripes; dorsal fin anteriorly largely dusky, 

 posteriorly pale with dusky spots; caudal pale, with dusky spots on 

 the raj's forming cross bars; anal largely dusky distally, with alter- 

 nating light and dark spots, at least at base; ventral dusky at base; 

 pectoral plain. 



The description is based on the type (U.S.N.M. No. 128221), from 

 Tortuga Bay, and a paratype from Independencia Bay, respectively 

 60 and 48 mm. (50 and 39 mm. to base of caudal) long, both taken
