OXYURICHTHYS 255 



almost a half longer, and extends to base of fifth anal ray; the 

 large pointed ventrals sometimes extend to anal and equal or 

 exceed head in length; the narrow caudal peduncle very short, 

 its depth 0.875 of its length and 2.7 times in head; the caudal 

 greatly elongated, the central rays with filamentous tips, 1.5 to 

 2.2 times in length and 1.75 to more than twice the length of 

 head ; the anal papilla elongate and pointed in males, short and 

 subglobose in females. 



The color in alcohol gray or yellowish gray, with a series of 

 six oblong, blackish brown blotches along middle of side, the 

 first under pectoral, the last on base of caudal ; alternating with 

 these is a series of blackish dorsal blotches, the first in front of 

 spinous dorsal, the last on top of caudal peduncle ; on ventral side 

 a series of six blackish bands going upward from anal fin, the 

 first at second and third anal rays; a dark brown spot under 

 eye, and a small circular black spot on upper part of eye, directly 

 above pupil ; a dark brown crossband on the naked space behind 

 eyes, passing from the origin of one oculo-opercular groove to 

 that of the other; two brown longitudinal lines, the character- 

 istic papilla of the genus, on each cheek, and two similar ones 

 on opercle; a blackish diagonal bar on opercle, from upper 

 posterior region running downward and forward ; on upper part 

 of pectoral base a large, irregular, dark brown spot; the nuchal 

 crest blackish; the first dorsal dusky with one or two whitish 

 crossbars on upper part, the filamentous prolongations black; 

 the soft dorsal has four or five alternating crossbands of whit-

 anal has a basal row of large black spots on the membranes, the 

 margin blackish; the basal portion of pectoral rays yellow, the

Here described from twelve specimens, 52 to 75 millimeters 

 long, collected by me at Cebu, September 16, 1925. None of 

 them was in breeding condition. 



This species recalls Gobius papuensis Cuvier and Valen- 

 ciennes, but is stouter, the depth one-fifth instead of one 

 seventh the length, has a characteristic eyespot not mentioned 

 by either Cuvier and Valenciennes or Giinther, the dorsal fins 

 are much higher, and the color markings are different. It dif- 

 fers strongly from the other Philippine members of the genus. 



Visayanus, because a native of the Visayan Islands.
