The above description is of a femal<\ The malc^ differs in having 

 longer iin rays; some of the anterior dorsal spines filamentous and 

 reaching past middle of base of soft dorsal; tips of last .dorsal rays on 

 the same vertical with those of anal; pectorals reaching to above fourth 

 or tiftli anal ray. No external inti'omittent organ. 



Color brown above lateral line, slightly mottled with small irregular 

 light spots; below lateral line white, spotted with a few brown spots 

 following along lower edge of lateral line; no cross t)ars or radiating 

 lines from eye; a' dark spot on last dorsal spines; pectoral with fine 

 spots in the female, with large spots in the male; soft dorsal with 

 oblique cross bands, much wider and blacker in the male; caudal with 

 3 or 4 wav^y cross bands; anal and ventrals white. 



This species resembles Cottlusculiis gom-s Schmidt, but differs from 

 it in having the nasal spine forked and in not having a ])road fold 

 across isthmus. 



The type and several cotypes were dredged by the U. S. Fish Com- 

 mission steamer ATbatrom^ at stations 37Y2 and 3773, off' Kinkazwan 

 Island in Matsushima Bay. The largest is 92 mm. in length. 



The type is in the U. S. National Mu.seum and is numbered 50923.
