from the eye smooth; a patch of minute tubercles along each side of suborbital stay; warts on opercle 

 above opercular ridge minute and collected into patches; below this ridge they are round and flat, 

 collected somewhat into chainlike bands, small patches of minute tubercles extending backward and 

 away from each segment of the lateral line, giving it a somewhat feathery appearance; a line of these 

 small projections terminates the lateral line at the base of the caudal fin; lateral line chainlike, of about 

 ■17 jointlike segments. 



Color in alcohol dark brown above, much mottled with irregular, small, thickly set white blotches, 

 this color extending up somewhat on the base of the fin membranes; lower half of side paler, consisting of 

 a white ground clouded over with minute brown punctulations; ventral surface, including chin and 

 breast, white; upper lip, maxillary, and membranes of upper jaw slaty blue; dorsal tins irregularly

 outwardly, making a dark brown band parallel with the edge of the tin. its distal border slightly wavy, 

 us proximal border deeply incised by sharp patches "i white projecting out between the rays, the outer 

 margin of the tin wholly white; anal white with '■'• dark vertical liars about half as wide as eye, these 

 about equal distances apart, the projecting tips of the rays always white; ventrals pale, mostly cloudy, 

 crossed with indistinct liars of lighter, pectorals dark In-own. a if\\- round small spots of white arranged 

 roughly in the form of liars; a narrow margin of the tin wholly white, the upper edge .if the tin showing

Specimen described :i female containing a few small eggs. 



This fish has a close general resemblance to I/;/oj n , phahu polyattttUhoci phalui. The presence of a 

 fourth preopercular spine, however, removes it from that genus. The character of the gill slit resembles 

 that of Myoxoa phattts, but the fourth preopercular spine and other minor characters place it better \\ ith 

 Oncocottus. Our specimen possesses many characters common to both genera, however, and it may be 

 found thai characters which have been considered generic in small individuals disappear in larger 

 ones. The gill slit, for instance, i- present on one side and absent on the other in this specimen.
