anal yellowish with pearly white spots ; pectorals, ventrals, and caudal 

 suffused with pink. 



In spirits the posterior light saddle and the two upper stripes remaui 

 perfectly distinct. 



UPENEUS CYCLOSTOMUS (Lacepede). 

 UPENEUS CHRYSERYDROS (Lacepede). 

 UPENEUS PLEUROSPILOS Bleeker. 



Three examples of this species were secured. The black lateral 

 spot does not seem to be a constant character, perhaps disappearing 

 with age. It is distmct in a specimen 150 millimeters long, scarcely 

 visible in one 240, and entirely absent in a larger example. 



Head 3.5 m length to base of dorsal; depth, 3.5; depth caudal 

 peduncle, 9.2; eye, 4.7 in head; width, interorbital space, 3.5; length 

 snout, 1.9; maxillary, 2.4; D. VIII, 9; A. 7; scales in lateral line 29. 



Body rather deep, the contour rising gradually from tip of snout to 

 origin of spinous dorsal. Eye nearer border of opercle than tip of snout 

 a distance equal to its diameter. Interorbital space high and strongi}^ 

 convex, this character becoming more pronounced with age. Max- 

 illary not reaching a vertical through anterior edge of orbit, its upper 

 edge fitting beneath edge of preorbital, the posterior edge rounded. 

 Barbels reaching a vertical through edge of opercle. Gill-rakers 6-17 ; 

 those on lower arch long and slender. Teeth in a single series on 

 jaws, strong and rather short. Scales weakly ctenoid. First dorsal 

 spine minute, the third longest, 1.5 in head; spines when depressed 

 not reaching base of second dorsal. Second dorsal low, the longest 

 (second) ray about equal to depth of caudal peduncle; anal slightly 

 higher. Caudal deeply forked, 1.2 in head ; pectorals 1.4; ventrals 1.4. 



Color in spirits : Opercle dark, the dusky lining of the inside showing 

 through; a faint dark spot below lateral line at a pomt beneath pos- 

 terior portion of spinous dorsal; absent on large mdividuals; scales 

 of upper part of body narrowly edged with darker, the center having 

 a somewhat lighter area. 



UPENEUS INDICUS (Shaw). 



Color in Hfe : Body above lateral line suffused with purple, slightly 

 greenish gray below, the light spot between the dorsals with a brassy 

 sheen; scales on upper parts narrowly edged with yellowish olive, 

 the color fading and almost disappearing ventrally; each scale of 

 lower parts with a pale brassy spot on its posterior edge; caudal 

 peduncle with narrow yellowish stripes in region of the black spot, 

 the body color here being almost white ; head colored like the body ; 

 a pearly blue stripe from tip of snout to lower margin of eye; snout 

 with vermiculations of same color; vermiculations and line followed 

 by narrow yellow stripes ; barbels white ; spinous dorsal pinkish, the 

 membrane anterior to each spme greenish yellow, soft dorsal pinkish
