 DORYPTENA OKINAWAE, new species. 



Head 4.2 in length to base of caudal fin; depth 6.2 ; deptli of caudal 

 peduncle 2.3 in head; eye 4.5; snout 4; D. VI-12; A. 9; P. 15; scales 

 in lateral series about 50; in transverse series above origin of anal 1G. 



Body elongate, subcylindrical, the caudal peduncle compressed. 

 Head broad, depressed, the cheeks bulging out beyond eyes which 

 are directed obliquely upward, their rims extending somewhat above 

 dorsal contour of head. Mouth terminal, broad, the maxillary not 

 extending posteriorly halfway from snout to eye. Head with many 

 conspicuous beaded dermal flaps and ridges; mucous pores of head 

 with pronounced rims or tubes; nostrils with large tubes. Tongue 

 small, narrow, truncate anteriorly. Teeth on both jaws simple, in 

 narrow bands, those of the outer row slightly enlarged; vomer and 

 palatines without teeth. Isthmus broad, the gill clefts extending 

 downward to a level with lower edge of base of pectoral. Gillrakers 

 long and pointed, 8 on lower side of arch. 



Head and breast naked; body except base of pectoral and breast 

 anterior to ventrals with imbricate, cycloid scales, a little larger pos- 

 teriorly where there are several greatly enlarged ones near middle 

 and posterior part of caudal peduncle; smaller anteriorly, minute and 

 crowded above base of pectoral. 



Dorsals separated by a distinct space; spines slender, the third or 

 fourth longest, l.G in head; tip of soft dorsal overlapping base of 

 caudal, the next to last ray longest, 1.2 in head; tip of depressed 

 anal not reaching base of caudal, the rays about equal in length to 

 those of dorsal. Caudal pointed. 2.7 in the length : 3 rays near middle 

 of fin conspicuously beaded by small tubercles. Pectorals pointed, 

 none of their rays detached, 3.5 in the length. Ventrals united, the 

 tips of rays free, giving edge of fin a frayed appearance; 4.7 in 

 length. 



Color in spirits brownish, with a faintly outlined dark saddle over 

 back near middle of spinous dorsal ; a similar though scarcely notice- 

 able mark below base of soft dorsal: a faint, narrow, dark band 

 extending backward from snout through eye to upper edge of gill 

 opening. Spinous dorsal clouded with dusky; other fins lightly 

 spotted on the rays; spots of dorsal and anal arranged in oblique 

 lines; those af caudal in somewhat broken vertical rows. 



Described from type Cat. No. (52240, U.S.N.M. ; length, 64 mm. 

 Locality, Xaha, Okinawa, where the species is rather common in the 

 tide pools. Cotype, Cat. No. 21100, Stanford University collection. 



Small examples are more brightly colored than the larger ones. 

 The background is lighter and the dark parts are more prominent 

 and well defined. A distinct dark band extends downward from eye, 

 and another appears on base of caudal.
