Ventral outline straighter anteriorly. Mouth large; mandihle somewhat 

 projecting, about 1^ in head; maxillary large, extending considerably 

 beyond orbit; snout (measuring from upper orbit) about 4 in head, | 

 length of eye ; intei'orbital about 9A in head ; eye 6 in head. Teetli moder- 

 ately strong, the anterior ones in the lower jaw somewhat larger than the 

 others; gill rakers 7 + 17, slender, weakly sei"rate, the Icmgest a trifle less 

 than eye. Scales cycloid, on cheeks, operclos and maxillary; snout, iutcr- 

 orbital, and mandible naked; accessory scales present, especially promi- 

 nent among the small crowded scales in the region below the pectoral ; 

 arch of lateral line 3i in straight part; pores about 38 -(- 82. Ventral S^in 

 head; pectoral 2; dorsal beginning above anterior rim of orbit; middle 

 rays of anal and dorsal longest, 2| in head, equaling width of caudal 

 peduncle; caudal double lunate, the middle rays the longest; pectoral of 

 blind side rounded, 24- in head. Color dark reddish brown, closely pep- 

 pered with darker dots; a series of indistinct white spots, 4 or 5 in num- 

 ber, following margins of the body, as in P. californicus; traces of darker 

 mottling along sides of body. Length 17 inches. 



This species, represented by a specimen from Magdelena Bay, Lower 

 California, is closely related to P. californicus, resembling it in the large 

 number and close arrangement of the gill rakers, but differing from it in 

 having cycloid scales, a greater number of fin rays, somewhat narrower 

 interorbital, and greater depth in proportion to the length.

The specimens described in the text (from Ma/.atlan and La Paz), under 

 the name Paralichthys adspcrsus, belong to a distinct species, thus far 

 known only from the west coast of Mexico and Central America and 

 which may be called Paralichthys sinalow, one of the many specimens taken 

 by the Hopkins Expedition at Mazatlan and La Paz being taken as type, 

 and the following as cotypes: Nos. 11726, 11727, 11728, 11729, 11730, 

 11731, L. S. Jr. Univ. Mus., all from Mazatlan. Paralichthys adspersits is 

 known only from the coast of Peru, the specimens before us being from 

 Callao. (Coll. Admiral L. A. Beardslee.) 



Paralichthys sinaloa' is distinguished from P. adspersiis by its cycloid 

 scales and Ijroader interorbital space. The gill rakers in P. adspernus are 

 close-set, rather long and sleudi^r, about | to f of eye, and with rather 

 slender sjiinules on the inner margin. In P. sinaloce they are set farther 

 apart on the limb of the gill arch, are shorter and thicker — about 2 in 

 eye — and have the inner edge armed with coarser teeth. All specimens of 

 P. sinaloa' have each 11 or 13 gill rakers on the lower limb of the arch, 

 while in 4 examples of P. adspersus, from Callao, there are 16 or 17 gill 

 rakers on the lower limb (19 in 1 specimen), and 7 or 6 above (5 in 1 speci- 

 men), showing that while there may be variation in the number yet it is 

 confined within limits which do not intergrade and the average number
