Color in life, body dark brown, each scale with a lighter area;

DORYPTENA TANEGASIM-ffi, new species. 



Head 5 in length to base of caudal fin; depth 7; depth of caudal 

 peduncle 2.5 in head; eye 4; snout 3.8; D. VI-15; A. 13; P. 15; scales 

 in lateral series about 57 ; in transverse series above anal about 18. 



Body markedly elongate, subcylindrical, the caudal peduncle com- 

 pressed ; head broad, depressed; cheeks bulging far out beyond eyes, 

 which are directed obliquely upward. Head with conspicuous beaded 

 dermal flaps and ridges which are definite and intricate in their ar- 

 rangement ; mucous pores of head with pronounced rims or tubes, 

 prominent among which are 2 minute black tubes on occiput; nostrils 

 with large tubes. Mouth terminal, broad, but with a very narrow 

 cleft, the maxillary not reaching over halfway to eye; tongue small. 

 narrow, truncate anteriorly; teeth simple, in narrow bands on both 

 jaws, those of outer row slightly enlarged, vomer and palatines with- 

 out 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. 



Sides of body with a series of 18 or 20 small, vertical, beaded ridges, 

 the longest about equal in length to cleft of mouth. Head entirely 

 naked; breast, base of pectoral and axil naked; scales of body very 

 thin, minute, cycloid, far apart, and deeply embedded in the epi- 

 dermis. 



Dorsal fins barely separate, their bases nearly connected by mem- 

 brane; spines slender and very flexible, the longest (third) contained 

 1.8 in head ; rays higher than spines, the next to last longest, about 

 equal in length to head. Anal lower than dorsal, not extending so 

 far posteriorly, although the tips of both overlap bases of upper and 

 lower caudal rays. Caudal sharply pointed and extremely long, 2.2 

 in the length. Pectorals with a strong muscular base somewhat like 

 that of Periophthalmus, the upper rays not separate, the middle ones 

 much the longest, about 4 in the length, the fin pointed like the 

 caudal. Ventrals completely united, the length about equal to that 

 of head. 



Color in spirits light brown, a minute white spot on each scale; 

 a conspicuous narrow dark brown saddle over back at middle of 

 spinous dorsal, posterior to which are 3 others, the third being the 

 most prominent, the fourth narrow, on end of caudal peduncle; head 

 with a faint dark bar extending from tip of snout through eye to 

 occiput, narrow anteriorly, broader posteriorly where it almost meets
