slender. Caudal fin narrow, more than f length of head. Second dorsal 

 and anal high. Lateral line disappearing under middle of second dorsal. 

 Color obliterated, traces of a black spot on spinous dorsal. Length of 

 specimen 3 inches. One of Dr. Hoy's types, in very bad condition, exam- 

 ined by ns. It has grown soft in weak alcohol, and its remarkable slen- 

 derness of body is perhaps, in part at least, dtie to this fact. Lake 

 Michigan, in deep water. (Named for A. L. Kiimlien, the ornithologist.)

2342. URANIDEA GRACILIS (Heckel). 



Head 3; depth 5. D. VIII, 16; A. 12. Body rather slender, fusiform; 

 preopercular spine moderate, concealed. Month rather large, the maxil- 

 lary reaching to the pupil; pectorals reaching front of anal; ventrals 

 about to vent. Color olivaceous, mottled, upper edge of spinons dorsal 

 red in life. Streams of New England and New York, recorded from tribu- 

 taries of the Connecticut, Lake Charnplain, Hudson, Delaware, and Sus- 

 quehanna; common; probably a variable form, including several of Dr. 

 Girard's nominal species, as Dr. W. O. Ayres vigorously insisted in 1845, 

 before the latter had been described, (gracilis, slender.)
