smallest, 62 in head; second ray of dorsal finlet is about twice the 

 length of first, its length 4 in head. 



Largest anal rays 3* in head ; about as long as second ray of 

 finlet ; the two small anal spines remote from the rest. Pectorals 

 short and broad, nearly 2 in head. Ventrals short, 2 in head, fold- 

 ing in a ventral depression. Caudal fin widely forked, lobes attenu- 

 ated and slightly larger than head. 



Body covered with small cycloid scales. Head not scaly, except 

 portions of cheeks and part of its dorso-caudal margin. Scales on 

 cheeks in about six series. Scales in regions of nape smaller than 

 those on upper portions of body, long and narrow. 



Color dark blue or lead above, becoming pale yellowish below. 

 Two conspicuous blue bands on sides of body ; the dorsal one begins 

 at the orbit and passes caudal to dorsal margin of caudal peduncle, 

 its width about equal to diameter of eyes ; the second begins at snout, 

 passes along ventral margin of orbit across opercle and a little 

 dorsal of base of pectoral fin to caudal. 



Caudal yellowish, with a darker margin ; ventrals, pectorals and 

 caudal yellowish, with more or less blue. 



The only difference we have been able to find between our speci- 

 mens and the description of E. biplnnulatus is, that in the latter the 

 preopercle is said to be crenulate, while in ours the preopercle is 

 entire ; hut as this is a character subject to variation at different 

 ages, we strongly adhere to Dr. Liitken's opinion that biplnnulatus 

 and pinnulatus are identical. Our description is taken from two 

 specimens, the larger of which was caught in Gravesend Bay, 

 September 21, 1885, and is in the Museum of the Indiana Univer- 

 sity ; the smaller (nine inches in length) was caught off Coney 

 Island, August 6, 1887 ; it is in the possession of the well-known 

 fish dealer, Mr. E. G. Blackford, of New York City.
