132 GOBIES OF THE PHILIPPINES 



The elongate body laterally compressed, the dorsal profile 

 horizontal from the full rounded nape to the caudal, convex 

 anteriorly, the ventral profile horizontal to anal, then ascendant 

 to caudal, the depth 6 times in length ; the head narrowed above, 

 3.58 times in length; the snout narrowed, convex, 3.7 times in 

 head; the eyes large, very high up, laterodorsal, inclined to- 

 ward each other and their inner margins touching, looking up 

 as much as sideways, equal to snout; the mouth oblique, with 

 projecting chin, the posterior angle of maxillary beneath front 

 margin of eye; the teeth in upper jaw in four rows, the outer 

 row with two or three pairs of stout, downward-pointed, some- 

 what curved canines anteriorly, the remaining teeth of outer 

 row of moderate size, widely spaced ; the next two rows minute ; 

 the fourth row has the anterior teeth much longer, slender, 

 pointed, inclined backward, and depressible, the remaining teeth 

 very small; the lower jaw has a short outer row of moderate 

 teeth, ending on each side in a stout curved canine; behind 

 this are two rows of small, slender, pointed teeth extending 

 far back; the tongue slightly crenate emarginate; four rows 

 of large scales on cheek, with a fifth row of small scales between 

 second and third rows; the opercles scaled on upper half; the 

 body covered with large, very finely ctenoid scales, those before 

 first dorsal smaller and extending forward to eyes; the tips of 

 second, third, and fourth dorsal spines elongated, threadlike, 

 the second a trifle the longest, 1.5 times the depth and 1.12 

 times in the head, reaching beyond base of third ray of second 

 dorsal when depressed; the second dorsal slightly lower than 

 depth, the posterior ray not reaching caudal when depressed; 

 the anal highest posteriorly, the last ray not quite reaching 

 caudal when depressed, the longest ray slightly exceeding depth ; 

 the depth of caudal peduncle !$ times in its length and 2 times 

 in head; the caudal shorter than head, 4.54 times in length; 

 the pectoral rather narrow, pointed, the central rays longest, 

 almost equal to head, 3.8 times in length; the broad, round- 

 tipped ventrals have a wide, deep, but thin frenum, 1.4 times 

 in head, their tip not nearly reaching the very short, blunt, 

 cylindrical anal papilla. 



Here described from a specimen, 100 millimeters in length, 

 collected by me in Lake Taal, Batangas Province, Luzon. 

 Several subsequent trips have failed to yield more specimens, 

 though the fish is well known to the fishermen. During certain 

 seasons it retires to deep water, and later trips have all been 

 made at those times.
