Spinous dorsal low, not notched, tlie first two spines shorter than the 

 others, which are of equal length and shorter than the soft rays ; length 

 of spines about equaling distance from snout to middle of eye, 3 in 

 head. Soft dorsal elevated, the anterior rays somewhat shorter than 

 the posterior, the tips of which reach rudimentary caudal rays, 2i in 

 head. Anal spines short and strong, the middle one stronger and 

 slightly longer than the third ; the second about equal to dorsal spines ; 

 anal rays more elevated than those of dorsal, the last ray the longest 

 and about equal to two-thirds length of head. Ventrals reaching vent, 

 pectorals slightly beyond it, two-thirds length of head; ventrals in- 

 serted in front of axil of i)ectorals. Caudal short, somewhat lunate, 

 with the outer rays produced ; the fin If in head. Dorsal and anal 

 scaleless. 



Head 2f in length; depth 3^. D. X, 12; A. Ill, 7; scales 5-50-15. 



Color : Body light olivaceous, the dorsal region with about 12 broad 

 dark brown cross-bauds extending from back tG below lateral line, 

 where they are interrupted, to reappear on the level of base of pectorals 

 as a series' of roundish blotches; those in front pinkish, behind brown. 

 A light streak from nape to front of dorsal, with two i^arallel ones 

 (usually indistinct) on each side of it. The brown bar immediately be- 

 hind soft dorsal is replaced by the ground color, but the corresponding 

 brown spot on sides is present. A brownish streak from snout through 

 eye to upper angle of opercle, clear brown anteriorly ; suborbital light 

 blue, with a narrow median streak of clear brown ; numerous clear 

 brown blotches on toi) of head, liase and axil -of pectorals largely pink, 

 the fin very finely barred (vermiculated) with pink and light blue. Dor- 

 sals reddish, with a median light streak, which disappears posteriorly on 

 soft dorsal ; distal part of soft dorsal with numerous small dark brown 

 spots, becoming light pink jiosteriorly and alternating with similar spots 

 of whitish or light blue. A dark brown spot at base of ventrals ; one 

 below base of pectorals, and one in front of the latter at margin of 

 gill-opening. Caudal brown at base and on outer rays, pink on inner 

 rays, vermiculated with irregular narrow light blue lines. Anal and ven- 

 trals light glaucous blue, thickly marked with brownish-yellow spots. 



Five or six specimens of this species were taken in a seine in the 

 Astillero (estuary), at Mazatlan. 



17. Lutjanus Colorado, sp. nov. (28386, 28305, -28261, 28383.) 



Body comj)aratively deep, highest at front of spinous dorsal, and with 

 an angle at origin of soft dorsal. Profile of back evenly arched to origin 

 of dorsal fin; ventral outline rectilinear to origin of anal fin, the base 

 of which fin is very oblique in the young, less so in the adult. 



Snout rather short, less acute than in L. prieto, less than one-third 

 length of head. Maxillary reaching nearly or quite to vertical from front 

 of pupil, 2| in head. Width of cheek from orbit to angle of preoperclo
