332 GOBIES OF THE PHILIPPINES 



bearing a row of sensory papillae; the top of snout, ocular re- 

 gion, and sides of head covered with long ridges bearing 

 sensory papillae; beginning above base of pectoral and running 

 back along middle of side to tail is a row of very short, vertical 

 bars of sensory papillate pores; the dorsals and anal each 

 densely enveloped in very thick, tough skin, and completely sep- 

 arated from caudal, which is narrow, with elongate-rounded 

 tip, a little shorter than head, about 7.3 times in length; the 

 small rounded pectorals about 3 times in head; the ventrals 

 very large, broad, with a narrow, strong frenum, longer than 

 caudal, 7 times in length. 



The whole body blackish brown, the head more or less bluish 

 gray, especially beneath; the caudal black, its upper and lower 

 margins whitish; the other fins all whitish. 



Here described from a fine specimen, 212 millimeters long, 

 collected during stormy weather in October, 1924, at Dumaguete, 

 Oriental Negros. 



I place here two small specimens, 90 -and 122 millimeters in 

 length, from Villa, Iloilo Province, Panay. They are dull lead 

 color, the wormlike body plump and rounded back to caudal 

 fin, which is black, very narrow, elongate, with threadlike tip. 

 I also determine as this species a specimen, 180 millimeters long, 

 from Hoihow, Hainan, one from Amoy, 125 millimeters long, 

 and one from Fu-chow, Fukien Province, China, length 130 mil- 

 limeters, collected by Light. A small specimen, 67 millimeters 

 long, taken in Pansipit River, just below Lake Taal, belongs 

 here, as do also three dusky pinkish specimens from Pampanga 

 River, 55, 105, and 110 millimeters long; the caudal is very 

 elongate. 



Six specimens, 45 to 75 millimeters long, from Ambulong, 

 Lake Taal, were received after the above was written. 



This species is very close in many respects to T. cirratus, but 

 is usually to be recognized at a glance by the color and the 

 differences in its fins. In very small specimens the eyes are dis- 

 tinctly visible. It occurs in both salt and fresh water, from the 

 coast of Bengal to the Indo-Australian Archipelago and southern 

 China. According to Day it varies much in color, but is mostly 

 of a leaden hue; "it is exceedingly vicious and when captured 

 snaps at everything near it ; should its tail be touched it springs 

 round and anything it seizes it holds on to in the most determined 

 manner."
