very nearly so, the preopercular spines small, and there is usually no trace 

 of teeth on the palatines. Cold streams and springs of the United States 

 from New England and the Great Lakes to the Pacific Coast, (ovpavos, 

 sky; eiSov, Hooked; I. e. stargazer.) 



a. Palatines with teeth. 



b. Dorsal VIII, 16 ; preopercle armed with 4 spines, the longest about 2 in eye: 



least depth of caudel peduncle 12 in length of body. BENDIREI, 2336. 



bb. Dorsal VI, 19; preopercle with a single short spine; least depth of caudal 



peduncle 8 in length of body. GHBBNBI, 2337. 



aa. Palatines toothless. 



c. Anal rays 14 or 15 ; dorsal spines 7 or 8. 



d. Preopercular spine short, bluntish; first dorsal dark, with pale margin. 



MARGINATA, 2338. 



dd. Preopercular spine well developed, broad, rather sharp, curved upward. 



TENUIS, 2339. 

 cc. Anal rays 12 or 11. 



e. Preopercular spine curved upward more or less abruptly. 

 /. Head large, about 3| in length. 



g. Mouth small, the maxillary barely reaching past front of eye;

 hooked abruptly upward, body very robust.

gg. Mouth larger, the maxillary reaching middle of eye; pectorals 

 usually reaching past front of anal; preopercular spine 

 stoutish, little hooked. 

 h. First dorsal nearly as high as second ; anal prickly. 



KUMLIENII, 2341.

Branchiostegals 6; D. VIII, 16; A. 12; V. I, 3; P. 15; C. 15. The length 

 of the type is 2.7 inches (69 mm.) to the base of the caudal. The greatest 

 height of the body at the origin of the dorsal equals its greatest width 

 over the base of the pectorals, and is contained nearly 4 times in its length 

 without caudal. The least height of the tail is -^ of the length without 

 caudal. The length of the middle caudal rays is contained 4 times in 

 the length of the body. Width of the mouth equals the length of the 

 head. The maxillary extends a little behind the front margin of the eye. 

 The snout is as long as the eye. The distance between the eyes is less 

 than their diameter, and is contained 5 times in the length of the head ; 

 the diameter of the eye 4 times. The length of the lower jaw equals 

 the length of head. Preoperculum armed with 4 spines, the largest at 

 the angle, and is about $ as long as the eye; the 3 anterior ones are very 

 small and hidden by the skin. The distance of the spinous dorsal from 

 the snout is of the length of the body ; the length of the longest spine 

 of the first dorsal is about of that of the head and about f of the longest 

 dorsal ray. The longest dorsal and anal rays are equal. The length of 

 the anal base almost equalsthe length of the head. The length of the
