and 27 to 34 times in length; the ventrals long, broad, pointed, 

 1.2 to 1.3 times in head, 10 to 12 times in length. 



The color in alcohol yellowish brown, finely punctulated with 

 rather sparsely scattered dots of darker brown; the caudal 

 darker to blackish brown, the other fins pale yellowish. 



Here described from seven specimens, 160 to 190 millimeters 

 in length, purchased in the Manila market. They came from 

 a bangos fish pond at Malabon. Sometimes they are caught in 

 large numbers when the fish ponds are drained. 



The Bureau of Science collection also contains a specimen, 

 212 millimeters long, in poor condition, obtained by Seale from 

 the Manila market in 1907. 



This species was originally described from Pondicherry, In- 

 dia, and is distributed throughout the East Indies. I have no 

 doubt it occurs all through the Philippine Archipelago. 

 Genus 74. SERICAGOBIOIDES g. nov. 



In both jaws there is an outer row of six or eight (ten?) 

 widely spaced, large, fixed, curved teeth, set outside the lip so 

 that the teeth and their roots are visible when the mouth is 

 closed, the teeth interlocking and covering the opposite lip 

 when the mouth is shut; behind outer row in each jaw is a 

 much longer row of very short, stout, conical teeth extending 

 almost to posterior angle of mouth ; behind symphysis of lower 

 jaw, inside inner row of teeth, is a pair of short, strong canines; 

 the body elongate, ribbonlike, the dorsals and anal continuous 

 with caudal, covered with a thin skin, the sixth dorsal spine 

 separated from the five preceding and from second dorsal; the 

 pectoral very long and pointed, equal to or exceeding head and 

 longer than the large pointed ventrals, which are slightly shorter 

 than head and partly adnate to belly; the long pointed caudal 

 1.5 to 2 times the oblong head; the tip of the thick tongue 

 rounded; there are no barbels, sensory ridges, or papillae on 

 head; the eyes very small, laterodorsal, distinct; the body ap- 

 parently naked anteriorly, with rudimentary scales embedded in 

 skin on posterior half, but with a strong lens widely scattered 

 scale pits can be made out along upper part forward to an- 

 terior end of trunk; the gill opening vertical, as wide as pec- 

 toral base, the isthmus broad, branchiostegals 5. Dorsal VI, 

 1-39 to 49; anal I, 38 to 44. Vertebrae 8 + 22. 



This genus is separated by its elongate pectorals, ventrals, and 

 caudal, and by the presence of but two rows of teeth in each
