CRISTATOGOBIUS 171 



with a posterior lateral pair of large, backward-curved canines 

 in outer row of lower jaw ; the head naked ; there are two widely 

 separated rows of minute papillae crossing preopercle longitu- 

 dinally, and one running downward and backward on opercle; 

 on the nape a thin, high, skinny crest, beginning between pos- 

 terior part of eyes and extending back almost to origin of first 

 dorsal, its height more than half an eye diameter; there is a 

 large open pore on anterior part of interorbital space and an 

 inconspicuous one on posterior part; there are about four large 

 pores in the groove running back from eye above opercle, and 

 two large pores on posterior margin of preopercle; the sides 

 of body covered with rather loosely attached ctenoid scales; 

 the sides of nape more or less covered with very small cycloid 

 scales, a series of seven to ten forward of first dorsal, but not 

 extending more than halfway to eyes; the first dorsal small, 

 with flexible spines, the second and third longest, but less than 

 the depth; the second dorsal and anal alike in shape and height, 

 the height a trifle more than that of first dorsal but still less 

 than greatest depth of body, their posterior rays scarcely reach- 

 ing caudal when depressed; the pectorals and ventrals pointed, 

 equal in length, reaching origin of anal; the pointed caudal 

 & or | longer than head; the anal papilla slender, pointed, 

 almost threadlike. 



The color in alcohol dark brown, with five or six paler cross- 

 bands on sides; on base of pectoral are two large black spots, 

 and scattered thinly over sides of head and forward half of 

 body are black dots; the nuchal crest deep chocolate brown; 

 the first dorsal dark brown, with a large blackish brown spot on 

 posterior part beyond fifth spine; the other fins are all plain 

 brown to blackish. 



Here described from two specimens, 25 and 22 millimeters 

 in length, collected by me under the wharf at Bungau, Sulu 

 Province. 



From Mr. F. Reveche, San Jose, Antique Province, Panay, I 

 have just received a fine adult male specimen, 36 millimeters 

 long, which differs in some respects from the above; the head 

 is 4.23 times in the length ; the tips of the first dorsal spines 

 are elongate, threadlike, 2.57 times in the length, 1.64 times the 

 depth; the second dorsal and anal are slightly less than the 

 depth, elongate and sharply angulate posteriorly, reaching the 

 caudal when depressed; the length of the pectoral equals that 

 of the head and is a tenth greater than that of the ventrals;
