40 GOBIES OF THE PHILIPPINES 



1.18 to 1.75 times in head; the anal is like the second dorsal, 

 both sharply angulate posteriorly, but is lower, its posterior 

 rays 1.5 to 1.8 times in head; caudal a little longer than head, 

 subtruncate, 3.27 to 3.9 in the length; the pointed pectoral 1.16 

 to 1.5 times in head; ventrals very narrow, elongate, with hair- 

 like tips, 1.16 to 1.4 times in head and often reaching the 

 elongate anal papilla, which is flattened or subcylindrical, with 

 a lunate, bilobed, and often expanded tip. 



The color in alcohol uniform blackish or brownish gray, the 

 pale grayish -ground color everywhere minutely punctate with 

 exceedingly minute blackish dots, thus giving the general effect 

 stated ; there is a conspicuous black spot or very short vertical 

 bar at base of caudal, rather below its middle; a black band 

 of coarse dots more or less evident, extending from the shoulder 

 down across base of pectoral ; on many female specimens there 

 is a broad, vaguely defined, dark lateral band from axil of 

 pectoral to caudal; females have the fins nearly unmarked, the 

 dorsals and anal clear, the membranes lightly specked with mi- 

 nute dark dots, the anal often clear with a dusky border ; caudal 

 clear or yellowish, the posterior part blackish or with dusky 

 crossbars; pectoral clear, ventrals clear or golden. 



Males have a very different color scheme; the upper half of 

 body, especially anteriorly, is often suffused with dark orange 

 red; the first dorsal deep black, with a clear or white basal 

 spot between first and third spines and fifth and sixth spines, 

 and a broad white crossband near top from first to third or 

 fourth spines, the tip above black ; sometimes there is a narrow 

 clear basal band instead of two spots; second dorsal intense 

 black with two to several circular white spots along base and 

 three to five circular white spots across upper part; sometimes 

 the spots coalesce to form bands; more rarely the fin is paler 

 and the spots or bands change position up or down or become 

 diagonal; the anal more or less golden or orange to clear, the 

 margin dusky to blackish ; or the anal may be golden anteriorly, 

 changing to white or clear posteriorly, the upper third blackish ; 

 caudal clear or golden, the posterior part blackish ; the pectoral 

 clear to lemon yellow, the ventrals yellow; anal papilla clear 

 yellow. 



I have studied one male specimen, the type, 33.5 millimeters 

 long, from the creek at barrio Puru, Legaspi, Albay Province, 

 and a large series of males and females from Rawis River, 

 Legaspi, Albay Province. The twenty-seven males vary from 

 24 to 33 millimeters in length; the eighty females, from 22 to
