at tip of jaw. Head and especially lips and maxillary covered with 

 small, fleshy papiihe. 



Pectoral reaching to above base of second anal ray; detached pec- 

 toral ray equal to distance from tip of snout to posterior border of 

 pupil. Ventrals adnate to T)ody for nearly their whole length, their 

 tips scarcely reaching to vent. Last dorsal spine the longest, 2| in 

 head; the longest dorsal rays equal in length the length of snout 

 and eye. 



Color of type nnich faded; light brownish above; lower parts of 

 body and head white; a light streak running along lateral line above 

 and below leaves it in a dark streak; each dorsal spine with a brown 

 spot on membrane behind its tip; soft dorsal with a large brown spot 

 on distal ends of lirst 6 rays, the rays crossed by light streaks; pec- 

 toral dark l)rown on its outer surface, white on its inner; ventrals and 

 anal dark l)ro\vn at tips of rays, shading to the white of body; tip of 

 caudal white, on distal third rays are crossed by a dark bar, which 

 divides below; in front of it is a wide light interval with a brown 

 spot in th(^ middle; then a narrow, dark, irregular l)ar across middle 

 of rays, and then a wide white area with traces of bars al)Ove and 

 below. Peritoneum white. 



This species is close to M/'nou.'^ rfdani.n^ differing in having a 

 smaller eye; the tip of the mandi))le more hooked upward; the lower 

 preopercular spines hooked backward, rather than truncate; the max- 

 illary slightly shorter; the ventrals shorter and more adnate; the pos- 

 terior outline of soft dorsal more l)roadly rounded; and in having the 

 caudal marked with irregular bars. In 3f. <f(I((///.si there is scarcely 

 any variation in the 2 broad bars crossing the caudal. 



The type is a specimen 115 mm. in length from Niigata, in Echigo, 

 presented to us by Dr. Ishikawa, of the Imperial Museum of Tokyo. 

 It is numbered 7380, Ichthyological Collections, Leland Stanford .1 unior 

 University Museum. It was formerly' No. 803, Imperial Museum.
