lower jaw, the latter when closed fitting snugly into the upper; head 

 entirely covered with flat, finely sculptured, bony processes; fins all 

 well developed ; pectorals rather less than half length of head ; dorsal 

 fin situated far back, its origin being but slightly in advance of that 

 of the anal, the extended rays of the latter almost reaching to the 

 caudal fin; caudal deeply emarginate; tlie anal fin of the male speci- 

 men much enlarged ; caudal peduncle elongate, its length measured 

 from anal fin to origin of middle caudal rays, being about equal to 

 the leno-th of the snout. 



Ctenolucius hujeta. 



Color in spirits: ITpper parts rusty (brownish) with faint hori- 

 zontal lines extending on the body from head to caudal ; lower parts 

 lighter, silvery; opercular flap silvery; eye dark on top, golden 

 around the jet-black iris, pupil a rusty yellow; dorsal, anal, and 

 caudal slightly dusky; pectorals and ventrals plain ; the black ocellus 

 at origin of caudal very conspicuous. 



Another example, a female 8 inches long, from the same source as 

 the foregoing, has slenderer jaws and a much smaller anal fin. A 

 third example from this lot was sent years ago to the Academy of 

 Natural Sciences of Philadelphia, where it is now preserved.
