Subgenus ORTHOPSETTA, Gill. 



3048. CITHABIl'HTHTS SORDIDUS (Girard). 

 (Soft Flounder.) 



Head 3? ; depth 2|. D. 95; A. 77; scales 65 to 70. Form elliptical; inter- 

 ocular space concave, scaly, a conspicuous sharp ridj^e above the lower 

 eye; mouth not large, the maxillary about 3 in length of head; teeth 

 anteriorly suhequal, growing much smaller behind. Gill rakers about 

 7 + 16. Lower pharyngeals narrow, each with 1 row of slender teeth. 

 Scales rather large, thin, and membranaceous, readily deciduous, their 

 edges slightly ciliate; accessory scales numerous. Eye large, much longer 

 than snout, 3^ in head; depth of caudal peduncle less than ^ head; pec- 

 torals long, nearly f length of head. Vertebra' 11 +29:= 40. Dull olive 

 brownish of varying shade, the males with dull orange spots and 

 blotches ; each scale with a darker edge ; dorsal and anal fins in the male 

 blackish, with dull orange blotches, and edged anteriorly with yellowish ; 

 female paler, the fins nearly plain. Pacific coast of North America, in 

 water of moderate depth ; British Columbia to Lower California. This 

 small flounder is one of the commonest species on the Pacific coast, being 

 found in water of 10 fatlioms or more depth in all localities from the Mex- 

 ican boundary to British Columbia. Although much larger in size than 

 any other species of the genus, it rarely exceeds 2 pounds in weight. In 

 its deciduous scales and soft flesh it much resembles Lyopsetta exUis and 

 Jtheresthes stomias, 2 species which are often taken in company with 

 it. Of all the species of CitharicMhys, this one has the most extended 

 range to the northward, {aordidus, sordid, from its dull coloration.)
