We liave six specimens wliich Ave refer to this species, tliough it is 

 not clear to us that Pristopoma leuciscufi elonr/atus Steind. can be sepa- 

 rated from l*risfopoma Icueiscn.s (riinther. The former is said to have 

 the body more slender, but Giinther gives the depth of the latter as 3 

 to 3.^ in length to base of caudal, and this agrees well with our e\:iiiiples. 

 Jordan &, (rilbert, in the Proceedings for 1881 {op. c/^.), si)eaking of 

 their siiecimens of Pomadasys leuciscus i'vom Mazatlan and Panama, say 

 that all but two "are slenderer, with more pointed snout and deeper sub- 

 orbital, the anal spines being quite small, the second 3^ to 4 iu head." 

 This of course means Steindachner's variety elongatus, i\i\i\ agrees with 

 ours, unless it be' that ours are but little if any slenderer than leuciscus^ 

 and tlu^ auiil spines are not qnite so small. The head of ours agrees 

 exactly with Steindachner's figure (as to shape, length of snout, depth 

 of suborbital, eye, membranous Hap upon border of anterior iiostiil,and 

 squamation of cheek), but in.^^tead of about seven rows of scales upon 

 the operde, there are but four or five, agreeing in this last respect with 

 Giinther's figure of leticiscus. The anal si)ines agree better with lends- 

 cu-j the second being large and strong (3^, iu head), and the third is 

 longer and more slender (less than 3-| in head). 



A light lateral band, about one scale in width, begins at the poste- 

 rior margin of the opercle jnst above the origin of the pectoral and ex- 

 tends backward in a direct line, meeting the lateral line un<ler the 

 posterior fourth of the soft dorsal, and continuing direct to the base of i 

 the caudal chiefly below the lateral line.
