NO. 1924. NEW PniLIPPINB ANACANTITINE FISHES— RADCLIFFE. 13? 



tip extending beliind base of third anal ray; pectoral equal in length 

 to filamentous ventral ray. 



Color in alcohol: Ground color of back dusky russet brown, 

 becoming lighter ventrally; belly with blackish shades showing 

 through scales; a small dusky area above opercle; a large circular 

 dark brown area extending from pectoral base upward to lateral line; 

 a broad saddle of similar coloration extending across back behind 

 origin of second dorsal; a second as far behind first as first is behind 

 origin of first dorsal, slightly lighter in coloration; basal sixth of 

 second dorsal spine light brownish yellow, distal portion dusky black, 

 the dark markings of this spine extending onto distal portion of soft 

 rays; second dorsal light; basal portion of anal light, distal portion 

 Dunctulate with darker, the marginal portion of fin anteriorly almost 

 black; ventrals dusky black, filament of outer ray whitish; pectoral 

 dusky white. 



Type.— C&t. No. 72948, U.S.N.M., 27 cm. in length, taken with a 

 beam trawl at station 5162 (lat. 5° 10' 00" N.; long. 119° 47' 30'' E.), 

 Sulu Archipelago, at a depth of 230 fathoms, on a bottom of coarse 

 sand and broken shells. 



Tliis species varies considerably in the form and length of the 

 snout, but the variations aie less marked than in O. commutdbilis, 

 and separation into distinct groups is impossible. It appears to be 

 related to C. australis and C. Mshinouyei, but is at once distinguished 

 from these species by the smaller number of keels on the scales.
