caudal, and anal tipped witli black; ventrals yellowish, spine and con- 

 necting membrane smutty; pectorals yellow, their base, the preorbital, 

 and upper part of head purple. Barbels very dark ; branchiostegal mem- 

 brane purple. Peritoneum light. 



According to Cuvier and Valenciennes TJpeneus crassilabris is " voisin 

 du cyelosiome. * * Ce poisson parait avoir etc jauue, avec des points 

 ou des lignes peu marquees sur les cotes. La premiere dorsale est vio- 

 lette; la seconde n'a que la base de cette couleur; la moitie superieure 

 est rayee de cinq a six raies paralleles longitudinales, alternativement 

 blanches et violettes. L'anale, beaucoup plus pale, a des points violets 

 et un plus grand uombre de raies obliques. La caudale est plus foucee 

 que la dorsale, et elle a des points blancs plus ou molns eftaces. Les 

 pectorales sont jaunes, plus ou moins olivatres. Les ventrales ont les 

 trois rayons externes colores en violet, et les internes jaunatres. La 

 membrane branchiostege et les barbillons sont d'un brun violet plus ou 

 moins fonce." 



11.— UPENEUS VELIFER sp. nov. 



Head ^ (3|); depth ^ (3|); D. YIII, 9 ; A. I, 7; scales 2-29-6. 



Allied to Upeneits trifasclatus (Lac.) Cuv. & Val. 



Body less robust than in TJ. crassilabris. Profile from beginning of 

 dorsal fin to a point above center of orbit, a gentle and regular curve; 

 thence to the snout a straight oblique line. Snout rather pointed, lower 

 jaw included; lips thin; maxillary 2f in head; eye rather small, high, 

 and far back, its diameter contained 3^ times in the snout (measured 

 obliquely from eye) and 5i times in the head. 



Teeth blunt, isolated, in a single series in each jaw; the overlapping 

 upper jaw shows all the teeth of the premaxillary in the closed mouth. 

 K"o teeth on vomer or palatines. A strong, blunt spine on opercle. 

 Gill-rakers 28 on lower limb. 



Barbels slender and long, extending slightly beyond base of ventral, 

 nearly as long as head. Scales ctenoid, moderate. 



Dorsal fins well developed ; third spine highest, equaling two-thirds of 

 the greatest depth, the spines following about evenly decreasing in 

 height to the eighth, which is two-sevenths of the third. In the second 

 dorsal the first ray is shortest, 3'^ in depth of body, all between the first 

 and ninth about equal and slightly higher than the first; the posterior 

 half of the ninth, or split ray, is 2^ times as high as the intermediate 

 rays, and exceeds the highest dorsal spine; when depressed it extends 

 onto the caudal one-fifth of the greatest length of the caudal; outline 

 of soft dorsal slightly concave. Anal about one-fifth higher than soft 

 dorsal; its last ray, however, is less produced, being six-sevenths of the 

 last ray of the dorsal, and, depressed, does not reach base of caudal; 

 anal outline somewhat convex from first ray to the split ray, which, 

 similarly to that ray in the soft dorsal, is produced beyond rest of fin. 

 The first ray of second dorsal and anal unbranched but plainly articu-
