■ 1300. CER TAIN BR YOSTEMMA FISHES— JORDAN AND SNYDER. 6 1 7 



Described from a specimen 160 mm. long, collected by Prof. O. B. 

 Johnson at Point Orchard, near Seattle, Washing-ton. 



Type. — N-o. 3150, Ichthyological collections, Stanford University. 



The type resembles closely the specimen figured by Bean, except 

 that the dorsal is not inserted quite so far forward as there repre- 

 sented, the pectoral is shorter, and the body and fins are not spotted 

 with white. The type is evidently a faded example which was more 

 brighth" colored in life. 



This species closely reseuibles Bryostemiiia-jtolyiictocephalum,^ the 

 character of the filaments, however, serving to distinguish them. In 

 the latter species the posterior interorbital pair are higher than the 

 anterior ones, many of the occipital ones are branched, there are a 

 num))er on the sides of the jaws, and those on the dorsal fin are fewer, 

 smaller, and less ornate. The species in hand is a much more slender 

 and less stoutly built form.

BRYOLOPHUS Jordan and Snyder, ne-^ genus. 



The genus for which the above name is proposed is re|)resented b}^ 

 Bt'yolojjhus lyxhiiH-s, a new s])ecies. It is apparently closely related 

 to Bryosteminn^ from which it is distinguished b}' having the teeth in 

 bands instead of in two closely apposed series with the tips aligned to 

 form a single cutting edge. 



Body clongiitc. compressed; mouth small; gill-mcniliranes forming 

 a fold acioss ihc isthnuis; teeth in narrow l)andsoii the jaws; no teeth 

 on the vomer and i)alatines: body with minute scales, the head naked; 

 lateral line represented l)y a short series of pores above the pectoral; 

 interorbital space and occiput with cirri; dorsal inserted above gill- 

 opening, of spines throughout; ventrals jugular; caudal distinct.
