no. 1836. NEW FISHES FROM JAPAN— SNYDER. 531 



rather wide, smooth space. Teeth of each jaw in a narrow, villiform 

 band, outside of which is a row of small canines; villiform teeth on the 

 palatines and vomer, the latter in a lunate patch; tongue naked. 

 Pseudobranchiae large; gill-rakers 5-0, the upper ones minute. 



Head with a row of enlarged scales extending downward from 

 posterior margin of eye to edge of maxillary; about six rows below 

 this on the preopercle; border of preopercle naked, the edge finely 

 serrated; opercle and subopercle scaled; occiput with two shields of 

 coarse scales; head elsewhere naked; back with sixteen scales between 

 occiput and insertion of dorsal; fins naked except the caudal, which 

 has minute scales extending almost to the tips of the rays. 



Third and fourth dorsal spines highest, about three in head; middle 

 rays scarcely shorter, the posterior one somewhat elongate, the tip 

 extending beyond edge of fin. First anal spine half the height of 

 second, the latter about a fourth of its length shorter than the third, 

 the length of which is contained 3.3 times in the head; anterior ray 

 three in head, the others gradually shorter except the last which is 

 similar to the last dorsal ray, neither dorsal nor anal reaching base of 

 caudal when depressed. Caudal deeply forked, the lobes equal and 

 pointed ; 3 .5 in the length. Pectoral very acutely pointed and slightly 

 falcate, its tip extending to a vertical through origin of anal. Ven- 

 trals acute, 1.5 in head. 



Color in spirits yellowish; a dark spot at upper edge of opercle, 

 where it covers the lower part of a broken brown band which extends 

 over the nape; a somewhat indefinite dark stripe having its origin 

 about midway between nape and first dorsal spine extends along 

 back below base of dorsal fin; a similar stripe, but less definite, 

 extends along the side just above the lateral line to a point below 

 end of dorsal, from where it passes upward and ends at base of 

 caudal; scales above the pectoral with more or less dusky color. 



The type, Cat. No. 68231, U.S.N.M., is a specimen 260 mm. long, 

 from the market at Naha, Okinawa. Another example, somewhat 

 smaller but differing in no other way from the type, is in the Stanford 

 University collection, cotype No. 21420. 



Family ILEMULID^. 



PENTAPUS FORMOSULUS, new species. 



An apparently new species is here described from one specimen 

 found in the market at Naha, Okinawa. It resembles P. microdon, 

 but it has a deeper body and a much smaller eye. 



Head 3.6 in length to base of caudal; depth 3; depth caudal pe- 

 duncle 0.3; eye 4 in head; snout 3; interorbital space 3; D. X, 0; 

 A. Ill, 7; scales in lateral series 45; between lateral line and spinous 

 dorsal 2; between lateral line and base of anal 12.
