]5ody ovate, compressed. Eyes on the left side, separated by a narrow ridge, 

 armed with one or more backwardly directed spines. Posterior nostril of blind side 

 small, without membranous valve ; olfactory laminae few, nearly parallel with each 

 other and with the main axis of the body ; no central rachis. Mouth small, the length 

 of the maxillary less than J that of head ; jaws equally developed, but dentition 

 almost entirely confined to blind side ; teeth small, pointed, scarcely enlarged 

 anteriorly, uniserial in both jaws ; vomer toothless. Gill-rakers very short, few in 

 number. Dorsal fin commencing above posterior nostril of blind side and just in 

 front of eye ; all the rays simple, scaled on ocular side. Tip of first interhaemal spine 

 not projecting m front of anal fin. Pectoral fins unequal, that of ocular side larger ; 

 all the rays simple. Pelvic fins short-based, that of ocular side with somewhat longer 

 base and placed on median line ; rays of pelvic of blind side not prolonged. Scales of

Two species from both coasts of tropical .America.' 



' Ginsberg has recently described a second species of this genus, but his paper was received too 

 late for inclusion in this monograph : 



Engyophrys scntus, Ginsburg, 1933, Proc. U.S. Xat. Mus., Ixxxii (20), p. 6. Described from a 

 single example (U.S.N.M., Xo. 91402), 83 mm. in total length, from off Dry Tortugas, Florida 

 (24^ 23'-25' N., 82^ 57'-58' W.), 50 fms. Said to differ from the Pacific species in having four 

 spines on the interorbitai ridge, spinous processes on the " ocular shelves ", less numerous scales, 

 and differently shaped body. The blind side is devoid of pigment.
