TUKUGOBIUS H9 



margin of preopercle; a broad furrow, marked by a row of 

 minute papillae and covered by a fold, extends from behind 

 angle of mouth back across opercle ; there are conspicuous pores 

 on the head as follows: On snout, anterior margin of eye, 

 central and posterior interorbital, postorbital, three on the very 

 prominent supraopercular groove, and three on the posterior 

 margin of preopercle. The dorsals are far apart, the last spine 

 of first dorsal barely touching origin of second dorsal when de- 

 pressed ; the central spines of first dorsal longest, 0.7 to 0.8 of 

 depth, or 2.1 to 2.4 in head; the second dorsal angulate, the 

 longest rays 0.8 to 0.9 of depth, the last rays reaching caudal 

 when depressed ; the anal shorter, its longest rays about equal to 

 first dorsal, not reaching caudal when depressed ; the caudal pe- 

 duncle broad, its depth equal or nearly equal to its length and 0.7 

 of depth of body, and 2.3 to 2.4 in head ; the caudal truncate with 

 rounded corners, 3.6 in length ; the broad, pointed pectoral, con- 

 tained about 4 times in total length, is a trifle shorter than 

 the caudal and extends back to a point above the anal papilla; 

 the ventrals are as broad as long, 0.8 of depth, twice or more 

 than twice in head, and extend two-thirds of the distance to 

 anus ; the anal papilla short, slender, triangular, pointed. 



The color in alcohol uniform deep blackish brown, or paler 

 and with a greenish tinge on belly; the fins all concolorous or 

 black. 



Here described from three specimens, 44 to 49 millimeters 

 in length, from Cabalian, Leyte. 



From Chlamydes laticeps, known from only a single specimen, 

 38 millimeters long, this species differs in the less-complete 

 scalation of the sides of the head, in the proportions, and in 

 the number of fin rays. In other respects it closely agrees, and 

 has the characteristic and peculiar cheek fold shown in the 

 figure of C. laticeps but not mentioned by Jenkins in his descrip- 

 tion.

Dorsal spines 6 or 7 ; head naked ; nape naked back to first dor- 

 sal or to above opercle with 12 or 14 rows of minute scales in

 series 12 to 16; scales on sides ctenoid, becoming very small 

 and cycloid above pectoral and never extending forward of 

 opercle on nape ; base of pectoral and breast always naked ; belly
