of the two species being distinct, since the numerous American 

 species of Paralichthys, with one or two exceptions, have a markedly 

 restricted distribution. No specimen of Paralichthys has hitherto 

 been recorded from that long stretch of coast in the western Atlan- 

 tic, extending from Florida or from Texas to Rio de Janeiro, except 

 one specimen of brasiliensis, which Giinther doubtfully referred to 

 Guatemala.^ From Paralichthys brasiliensis (Ranzani),^ which occurs 

 nearer the range of the present species, tropicus may be distinguished 

 by the lesser number of gill rakers and the more numerous accessory 

 scales. The difference between the present and other closely related 

 species will be taken up in greater detail in a monographic study of 

 the genus Paralichthys now in course of preparation. 



Subfamily Bothinae 



Genus ENGYOPHRYS Jordan and Boilman 



ENGYOPHRYS SENTUS, new species 



Description of type. — Sinistral. D. 79. A. 64. Lateral line with a 

 high arch in front and well developed on eyed side, each scale having 

 a raised longitudinal canal or a groove; almost absent on blind side, 

 no trace of arch and no well-developed canals or grooves on scales, 

 only a few having a feeble dent or groove near center. Anterior 

 accessory branch of lateral line feebly developed on eyed side, short, 

 V-shaped, disconnected from main lateral line. Scales ctenoid on 

 eyed side, cycloid on blind side, quite large, 14 in curve of lateral line, 

 37 in straight part to end of hypoural and 1 similarly large perforate 

 scale on base of caudal. Scales cover entire head and body, except 

 snout and lower jaw. No accessory scales. Gill rakers very short, 

 pimplelike, 4 on lower limb of first gill arch on blind side, 6 on eyed 

 side; upper limb almost smooth on bUnd side, 3 very minute, hardly 

 perceptible protuberances on eyed side. Mouth very small, maxil- 

 lary falUng short of anterior margin of eye. Eyes large, the lower 

 having its position somewhat more anterior than the upper. Inter- 

 orbital narrow, reduced to mere ridge, with four spines more or less 

 directed backward, the first in a Hne with anterior margin of lower 

 eyeball and but shghtly inclined backward, the third nearly over 

 middle of lower eye and strongly inchned to horizontal, the first three 

 about evenly spaced and gradually making a more acute angle with 

 a horizontal plane; the fourth spine blunt, horizontal, and more 

 remotely spaced, situated just behind posterior margin of lower eye- 

 ball. A spinous process on ocular shelf, in front of upper eye, directed 

 upward; two such processes in front of lower eye, approximate and 

 more or less directed downward. Teeth absent on eyed side (none 

 seen on examination with a binocular microscope on undissected fish) ;
