Prognathodes, GILL, Proc. Ac. Nat. Sci. Phila. 1862, 238 (pelta~aculeatug ; name only). 



This genus is intermediate between Chelmon and Chcetodon, having the 

 produced snout of the former and a fin formula more like that usually 

 seen in the latter. Scales large. One species known, (rtpo, before; 

 yydOog, jaw; sidot, likeness.) 



2083. PROGNATHODES ACULEATUS (Poey).

 erately produced, about 4- length of head; profile steep, concave. Maxil- 

 lary reaching to middle of snout. Angle of preopercle rounded, minutely 

 serrate. Dorsal spines long and very strong; fourth spine 2 in depth; 

 membrane between spines deeply notched; soft anal higher than soft 

 dorsal, their basal halves alone scaled ; caudal truncate. Uniform reddish

658. FORCIPIGER, Jordan & McGregor. 



Forcipiger, JORDAN & MCGREGOR, new genus (longirostris). 



This genus differs from Chelmon, Cuvier, in the long and high spinous 

 dorsal, which is composed of 12 stout spines (9 in Chelmon). The snout, 

 as in Chelmon, is very long and slender, bearing the short, forcep-like 

 jaws at the end. From Prognathodes, a genus still more closely related, 

 Forcipiger differs in the small scales, there being about 75 in a horizontal 

 series. Pacific Ocean. Two closely related species known F. longirostris 

 (Cuvier & Valenciennes) from the East Indies, and the following, (forceps, 

 tweezers ; gero, I bear. ) 



2084. FORCIPIGER FLAVISSIMUS, Jordan & McGregor, new species. 



Head 2i; depth 2; eye 6| in head. D. XII, 22; A. Ill, 17; snout If in 

 head. Body short, strongly compressed, its outline angular; anterior 

 profile very steep, concave. Mouth small, at the tip of the projecting 

 snout; cleft of mouth 1| in eye. Scales quite small, ctenoid, 9-75-35, 

 irregularly placed, smaller on head and bases of fins, the rows along lateral 

 line parallel with it only anteriorly, those below run horizontally on lower 

 parts of the body and irregularly upward and backward above; lateral 

 line concurrent with the back. Dorsal spines extremely strong, fifth
