no. 1836. NEW FISHES FROM JAPAN— SNYDE&. 535 



Body markedly deep the dorsal and ventral contours evenly 

 rounded, the dorsal more elevated than the ventral. Eye large, its 

 longitudinal diameter greater than length of snout and about equal 

 to distance between orbit and edge of opercle; interorbital area broad 

 and convex. Suborbital and preopercle covered with scales, the 

 edges smooth. Teeth simple, scarcely compressed, in a single row, 

 closely apposed. Maxillary extending just beyond a vertical through 

 anterior edge of pupil. 



Lateral line discontinued beyond middle of soft dorsal ; no pores on 

 the caudal peduncle, but each scale in the median row with a minute 

 pit. Scales of head and body denticulate; bases of dorsal and anal 

 with a sheath of scales; membranes of dorsal, caudal, and anal with 

 minute scales; snout naked. 



Fourth, fifth, and sixth dorsal spines longest, 1.3 in head; soft 

 dorsal and anal elevated, the dorsal rather pointed; height of fins 

 about 1.2 in the head. Caudal deeply cleft, the lobes with acute tips. 

 Pectoral pointed, its length a little less than that of head. Ventrals 

 pointed, the tips filamentous, reaching base of second anal spine. 



Color in spirits deep brown; a narrow, oblique, white band passing 

 across body from base of ninth dorsal spine to origin of anal; upper 

 edge of pectoral with a black spot which spreads downward and 

 becomes diffuse over the base of fin. 



This description is of the type, Cat. No. 68234, U.S.N.M., an example 

 70 mm. long from a pool at Tanegashima. Three smaller specimens 

 were collected at the same time, one of which is numbered 21423 

 cotype, in the Stanford University collection. 



In young individuals the white band is somewhat more distinct, an 

 occasional example showing it very sharply outlined, and also fol- 

 lowed by a second which is separated from the first by about four 

 scales. 



A few young specimens were found in the pools at Misaki. Other 

 examples of the species were earlier identified by Jordan and Snyder 

 as Chrysvptera melas. They differ from that form in having the light, 

 oblique band, the sharply pointed caudal lobes, and the black spot 

 at the base of pectoral. For like reasons this species can not be 

 identified with Glyphisodon violaceus Brevoort. 



The species is named for Mr. Austin Hobart Clark. 



Family OSTKACIID^E. 



LACTOPHRYS TRITROPIS, new species. 



This species differs from others known to the Japanese fauna in 

 having the carapace three angled. It differs from 0. concatenatus \ 

 in the strong spines of the dorsal and lateral ridges. It does not
