attained; which, taken with its deep-water habitat and different spawning season from 

 that of P. americaniis , seem sufficiently distinctive. 



Pseudopleuronectes dignabilis Kendall, new species. 



Head, 4.5 in length without caudal; depth, 2.2; eye, 6.5; snout, 5.4 in head; dorsal, 68; anal, 50; 

 scales, 85. 



Body broadly elliptical, dextral, its greatest depdi about in a line between the twenty-seventh 

 dorsal and eleventh anal rays; lateral line nearly straight; distance from the posterior end of the dorsal to 

 base of upper caudal ray equal to distance from posterior end of anal to base of lower caudal ray, about 

 2.66 in head and less than the \ridth of the narrowest part of the caudal peduncle, immediately back of 

 the vertical fins, which is about 1.75 in head; scales on right side strongly ctenoid but entirely smooth 

 on left ; scales extending nearly to tips of most of the rays of all of the fins on right side ; first 1 5 and last 

 6 dorsal, and first 5 and last 6 anal rays without scales; fortieth dorsal ray about equaling twenty-sixth 

 anal ray in length, the longest ray in each fin about 1.9 in head; pectoral moderate, 1.60 in head; 

 ventral short, about 2.60 in head; head comparatively short, almost entirel)' scaled on right side and 

 wholly naked on left; mouth small, lips thick, the lower widi a sort of thick triangular projection at its 

 symphysis, turned somewhat to the right; close set incisor teeth in both jaws, mostly on the blind side; 

 gape much less than the length of upper jaw (maxillary and premaxillary); upper jaw 4, mandible about 

 2.70, in head; preorbital in widest part about 7.40, snout (consisting of preorbital and premaxillary 

 widths) about 4.20 in head; eye moderate and prominent; interorbital almost flat and scaly, more than 

 } eye, about 10.20 in head. 



Color: generally light yellowish-brown with irregular wash of lemon j-ellow; center of each scale 

 bluish-gray, the brown forming a broad margin; some variously sized blotches of darker brown, the 

 brown covering the scales, but their margins still darker; faint whitish blotches, with an approach to 

 regularity of arrangement, appearing on margins of body dorsally and ventrally near bases of the vertical 

 fins, one on each side of the caudal peduncle, and some somewhat alternately along each side of lateral 

 line; margins of preopercle and opercle, also branchiostegals and some of the fin-rays, lemon yellow. 



Type, a female 22 inches long (no. 73918, U. S. National Museum) from Georges Bank. (Dignabilis, 

 worthy.)
