280 GOBIES OF THE PHILIPPINES 



contained a little more than 6 times, the head 3.77 times in 

 length; the short snout very wide, convex, then almost truncate 

 in front, 4.5 times in head; the eyes dorsal, prominent, approx- 

 imately equal to snout, and very close together, the interorbital 

 space less than half an eye diameter ; the horizontal mouth ter- 

 minal, low down, the lower jaw somewhat included. The poste- 

 rior angle of maxillary beneath hind margin of eye; eighteen or 

 twenty teeth in upper jaw, vertical, strong, extending a little 

 farther back than in lower jaw, which has sixteen strongly bifid 

 teeth inclined outward; the snout and sides of head naked, the 

 nape covered with very fine scales, the anterior ones scattered; 

 the depth of caudal peduncle equals distance from dorsal to 

 base of caudal but is 2.5 times greater than distance from anal 

 to caudal; the narrow pointed pectorals equal the ventrals in 

 length; the dorsal spines equal depth; the soft dorsal and anal 

 similar in outline, their rays equal in length, shorter than the 

 dorsal spines ; the lanceolate caudal equals the length of head ; 

 the posterior scales on sides of body are larger than those ante- 

 riorly and are easily dislodged. 



The color in alcohol yellowish, with underside of head and 

 belly muddy gray; circular dark brown spots on sides of head 

 and base of pectoral ; a series of irregular brown spots and cross- 

 bands along sides of body ; the tips of pectorals black ; margins 

 of vertical fins and caudal more or less dusky or blackish. 



Here described from the type and only specimen, 34 milli- 

 meters long, collected at Odiongan, Tablas, by Edward H. Tay- 

 lor, an authority on Philippine Reptilia, for whom I take pleasure 

 in naming this distinct species. 



This is close to A. secdei sp. nov., but the scalation is different 

 and the color markings also differ. In default of more material 

 the gap between them is too great to warrant placing them 

 together. 



Genus 60. TRIAENOPOGON Bleeker 



Triaenopogon BLEEKER, Arch. Neerl. Sci. Nat. 9 (1874) 312. 



This genus is recognized at once by the presence of con- 

 spicuous fringes of barbels along the edge of the preorbital and 

 suborbital regions and on the lower jaw and margin of the 

 preopercle, and by the possession of two rows of teeth in each 

 jaw, the outer tricuspid, the inner smaller, simple, pointed. 



The body robust, with a very broad, low head, 35 to 40 scales 

 in a longitudinal series, the head and nape scaleless except for 

 a few rows before first dorsal and above opercle; the vertical
