38 GOBIES OF THE PHILIPPINES 



7. HYP8ELEOTRIS AGILIS sp. nor. 



PLATE 2, FIG. 3 



Dorsal VI, 1-8 or 9; anal I, 9 or 10; there are 25 scales in a 

 longitudinal series, 10 in a transverse series, and 15 between 

 the tip of the snout and the first dorsal fin. 



The body laterally compressed, its depth 3.5 to 4 times in 

 the length; the dorsal profile descends to snout in an almost 

 straight line; the head depressed, its length a little more than 

 3 to 3i times in the length; the eye from 4.4 to 4.8 times in 

 the head and as long as or a little less than the bluntly round 

 snout, which is sharply elevated above; the rounded interor- 

 bital space equals eye; the leant depth of caudal peduncle twice 

 in its own length (in one specimen T ? of its length) ; the caudal 

 much shorter than head, 4.5 to 5 times in the length; the anal 

 papilla small and inconspicuous. 



The entire body covered with rather large scales; those on 

 head and predorsal and preventral regions cycloid, the remain- 

 der ctenoid; s.Tiall cycloid scales on base of caudal; the scales 

 on top of head extend forward to base of hump on snout. 



The color in alcohol yellowish, crossbarred with darker bands, 

 which form eight dark spots along middle of each side : two nar- 

 row diagonal dark brown stripes run from eye backward across 

 preopercle and on to operculum; a faint longitudinal stripe on 

 operculum and one from eye backward above preopercle and 

 opercle; the second dorsal irregularly ci'ossbarred with dark 

 brown; the other fins more or less faintly dotted with darker; 

 an indistinct dark crossbar on base of pectoral. 



Here described from the type, No. 10143 Bureau of Science 

 collection, and thirteen cotypes, which I obtained from a creek 

 flowing into Lake Mainit, near the barrio of Mainit, Surigao 

 Province, Mindanao. 



This little fish is like no other mentioned in the available lit- 

 erature. The diagonal stripes on the side of the head give it 

 a great resemblance to the young of Ophiocara aporos. The 

 specimens seen were playing about in the current of a small 

 creek, after the manner of Cyprinidse, very unlike the habit of 

 gobioid fishes. 



Agilis, nimble.
