 Stejueger. 



This species has the liyoids feebly developed. Similar in form in 

 S. malma, but with a less elon^^ate and stouter body. The length oi 

 the head is about equal to the heij?ht of the body, and is contained 

 4i to 43 times in the total length without caudal. The eye is two- 

 tliirds as long as the snout; it equals about one half the width of 

 inteiorbital space, and is contained 5^ times in the length of the head. 

 The maxilla extends to or beyond the vertical through the hind margin 

 of the orbit, the ni)per Jaw being nearly one-half as long as the head. 

 Lower Jaw slightly shorter than the upper. Scales small, about 30 in 

 a transverse series from the origin of the dorsal to the lateral line; 

 105 rows in the lateral line, 122 of which bear i)ores. 



All the fins short; dorsal nearly midway between tip of snout and 

 root of upper caudal lobe, its base nearly as long as longest ray, half 

 as long as the head: its upper margin very slightly concave; last ray 

 one-half as long as the longest. The adipose fin is placed over the 

 end of the anal, its width about equal to one-half its length, which is 

 about equal to the length of the eye. The length of the pectoral is con- 

 tained from 7 to 7i times in the total without caudal. The ventral is 

 placed under the middle of the dorsal; it does not nearly reach to the 

 vent; its length is about one-half that of the head. Ventral ap])endage 

 minute in some si)ecimens, in others nearly as long as the eye. The 

 caudal is emarginate, its middle rays, measured from the end of the 

 scales, one-half as long as the outer. The anal is scarcely concave 

 when expanded. 



Pyloric ca^ca 22; branchiostegals 12. Gill-rakers (3-f 10, the longest 

 less than one-half length of eye. 



Color bluish gray above, whitish below; the sides with numerous 

 large white spots, some of which are two-thirds as long as the eye. 



Four individuals were obtained in the inner harbor by Dr. Stejneger 

 among the herrings. He says it is called Kundscha.
