first ray ; edge of membrane more deeply incised between spines than 

 between rays; highest spine 1.6 in head; ray 1.3. Origin of anal 

 below eleventh dorsal spine; third, fourth, and fifth rays elongate; 

 neither anal nor dorsal attached to caudal by membrane. Caudal 

 truncate, the length equal to that of head. Pectoral rather pointed, 

 nearly equal in length to head. 



Color in spirits pale brownish gray, the black peritoneum showing 

 through the abdominal walls; a dark spot on upper part of opercle; 

 edge of preopercle dusky; chin and upper lip mottled; body with an 

 irregular series of small, round, sharply defined, black spots along 

 upper side, below and above which are numerous dark specks, some 

 of which are closely clustered, forming vermiculations on sides of 

 abdomen. Dorsal dusky; a series of indistinct, elongate, narrow bars 

 extending obliquely upward and backward from base to near middle 

 of fin; caudal speckled on median portion; an indistinct, dusky spot 

 on posterior part below center of fin; anal dusky, with an indistinct, 

 white border and a light basal area. 



Described from the type, Cat. No. 62246, U.S.N.M., an example 43 

 mm. long, from Naha, Okinawa. Cotype, Cat. No. 21111, Stanford 

 University collection. 



The filamentous anal is a character peculiar to the male sex. The 

 female differs from the male in this particular only, the anterior anal 

 rays being somewhat shorter than the others. The females appear to 

 be slightly larger than the males. In 6 specimens there are 18 to 20 

 anal rays. 



The species resembles S. undecimalis ° from the Philippines. It 

 differs from S. undecimalis in having a branched nostril tentacle, 

 scalloped upper lip, a less projecting forehead, and in color. 



ENCHELYURUS HEPBURNI, new species. 



Head 4.5 in length to base of caudal; depth 4.4; depth of caudal 

 peduncle 2.5 in head; eye 3.5; interorbital space 4; D. XII, 17; 

 A. 22 ; P. 13. 



Body deep; the head large. No crest or filaments; a small flap 

 on nostril. Each jaw with a row of strong, flat, closely apposed 

 teeth bordered on either side by a very strong, curved canine. No 

 pseudobranchise ; gillrakers very short and blunt. Gill opening re- 

 stricted to a small slit somewhat less in width than diameter of eye, 

 and entirely above the base of pectorals. Dorsals without notch, the 

 origin directly above gill opening, the posterior part connected 

 with caudal by membrane; articulated rays IS, none of which are 

 branched; longest rays near posterior part of fin, their length con- 

 tained 1.5 in head. Anal originating below tenth dorsal spine, con- 

 nected with base of caudal by membrane; the longest (posterior)
