260 GOBIES OF THE PHILIPPINES 



The species is very closely related to O. microlepis Bleeker, 

 but is usually much thicker and plumper. Slender individuals, 

 on which the lateral spots have faded, have a remarkable re- 

 semblance to O. microlepis, but are readily distinguished by the 

 presence of the tentacle on the eye. 



Originally described by Bleeker from Ternate, it has been 

 found in fresh water in the Fiji, Samoa, and Society Islands. 



128. OXYURICHTHYS VIRID1S sp. nov. 



Dorsal VI, 1-12; anal I, 13; there are about 52 scales in a 

 lateral series, 18 in a transverse series, and 17 or 18 scales 

 before first dorsal. 



The body elongate, thin, with strongly compressed sides, its 

 greatest thickness twice in the depth, which is 5.4 to 6 times in 

 the length; the head 3.8 to 4 times in length, its breadth less 

 than its depth, 0.85 to 0.95 of the latter ; the snout short, blunt, 

 3.5 to 4 times in head ; the eye as long as snout or as long ; the 

 tentacle on eye very short, its length 2.5 to 5 times in eye; the 

 posterior margin of eye a trifle nearer tip of snout than to 

 posterior extremity of head; the breadth of interorbital area 

 contained 2.5 times in eye; the oblique mouth moderately large, 

 the posterior extremity of maxillary reaching to middle of 

 pupil or beyond; there are eighteen or twenty teeth on each 

 side of upper jaw and two or three rows on lower jaw, the inner 

 row largest, the middle row smallest, if present; the teeth in 

 upper jaw much larger than those of lower jaw; the depth of 

 caudal peduncle is 2.1 to 2.3 times in head; the long pointed 

 caudal 1.8 to 2.1 times in head and body together; the dorsal 

 spines elongate, threadlike, the first one as long as or 0.2 longer 

 than head ; the penultimate posterior ray of second dorsal equals 

 the longest dorsal spines, the ultimate one much shorter; the 

 anal similar but lower, its posterior rays longer than body depth ; 

 the posterior rays of both anal and second dorsal extend well 

 upon caudal when depressed; the pointed pectoral may extend 

 back as far as first anal ray; the ventrals rather short, not 

 nearly reaching anus ; the anal papilla long, slender, and pointed. 

 In other respects it agrees with O. ophthcdmonema. 



In life the color was pale yellowish gray, with about five 

 indistinct, dusky crossbands over back, the sides more or less 

 shot with golden green ; the head and inside of mouth were also 

 golden green; the eyes were lapis lazuli, with a deep red ten- 

 tacle ; a rounded blackish spot at base of caudal ; a whitish bar 

 on base of pectoral with a dusky bar above and below it.
