258 GOBIES OF THE PHILIPPINES 



gently arched from chin to base of caudal, the depth 4.5 to 5.1 

 times in length; the head of moderate size, 3.5 to 3.8 times in 

 length, its breadth equal to its depth; the snout short, blunt, 

 convex, its length 3 to 3.5 times in head; the eyes dorsolateral, 

 high up, 4.16 to 4.8 times in head and 1.3 to 1.6 times in snout, 

 the posterior margin of eye about equidistant between tip of 

 snout and posterior extremity of head; on upper posterior part 

 of eye, just within the margin, is a slender, pointed tentacle, 

 an outgrowth of the sclerotic coat, its length 1.6 to 3 times in 

 diameter of eye; the interorbital space very narrow, its breadth 

 or a little more than i of eye; the posterior angle of maxil- 

 lary extends to a point beneath pupil or beyond ; there are about 

 twenty-five teeth on each side of upper jaw, in a single row; 

 the teeth of lower jaw in three or four rows; in the first in- 

 stance the two outer rows are minute, those of the innermost 

 one at least twice as large; when four rows are present both 

 the outer and the inner rows are larger than the middle ones ; the 

 opercles, preopercles, snout, and nape above the preopercles are 

 scaleless and marked by the lines characteristic of the genus; 

 a low scaleless ridge bearing a low skinny crest extends from 

 first dorsal forward on nape ; no scales on base of pectoral ; the 

 tips of the dorsal spines more or less threadlike, those of the 

 first four usually elongated and longer than head; sometimes 

 the first one is excessively long and threadlike, extending back 

 beyond posterior end of base of second dorsal; the first four 

 rays of second dorsal lower than body, but the rest all higher 

 than body, the second from the posterior end longest and equal 

 to head; the anal similar in shape but not quite so high, the 

 longest rays a little less than head; the posterior rays of both 

 dorsal and anal extend well upon caudal when depressed; the 

 depth of caudal peduncle 2i to 2f in head; the caudal elongate 

 and pointed, about 1.8 times in head and body together and a 

 little more or less than twice the length of head; the elongate 

 pointed pectorals may extend to above the third or fourth anal 

 ray; the ventrals may extend to origin of anal; the anal papilla 

 short, slender, pointed. 



The color in alcohol dark reddish brown to whitish, with six 

 short, blackish brown crossbars on back and a row of five or 

 six large, blackish brown blotches along middle of side, the one 

 at base of tail darkest; the dorsal scales on anterior half may 

 each have a small dark bar or spot along posterior margin ; there 

 are traces of narrow crossbands extending from dorsal bars to
