250 GOBIES OF THE PHILIPPINES 



They both lack the blue spots on the base of the pectoral and 

 the yellow submarginal band on the caudal which one usually 

 notices on G. arabicus. 



Two examples from a coral reef at Paracale, Luzon (Peters) . 



The above highly unsatisfactory description is all that we 

 know about this species. It is evidently an Oxyurichthys, but 

 the description is remarkable for what it omits rather than for 

 what it gives. 



Gobius arabicus has "very small scales ; the height of the 

 body 7 times in the total length, the length of the head 4.5; 

 cheeks swollen, head as broad as high, but a third longer than 

 high; canine teeth in the upper and lower jaws; the second and 

 third dorsal spines higher than the body; caudal pointed, one- 

 fifth of the total." (Gunther.) 



The "total length" probably includes the caudal fin. 



122. OXYURICHTHYS AMABILIS Seale 



Oxyurichthys amabilis SEALE, Philip. Journ. Sci. D 9 (1914) 76, 

 pi. 2, fig. 1. 



Dorsal VI, 1-12; anal I, 13; there are 50 scales in a longitu- 

 dinal series, 21 in a transverse series, and 24 before first dorsal. 



The body elongate, the head and trunk laterally compressed, 

 the dorsal profile of head convex, the dorsal and ventral outlines 

 tapering gradually from head to caudal peduncle, the depth 6 

 times in length; the head large, 4 times in length, the anterior 

 profile strongly convex, its breadth f of its depth, which is 

 scarcely more than 0.6 of its length ; the snout 3.3 times in head ; 

 the eyes very high up, dorsolateral in position, about 4 times 

 in head, their inner margins very close together and projecting 

 above dorsal outline of head, the interorbital space linear; the 

 teeth in upper jaw in one row, of moderate length, stout, some- 

 what curved ; in lower jaw there are two rows of very small teeth, 

 not one row as stated by Seale; the mouth large, oblique, the 

 posterior angle of maxillary beneath front margin of pupil; the 

 scales on posterior part of body large, those on anterior portion 

 much smaller, those in front of first dorsal very small and 

 extending forward to mucus channel behind eyes ; the first dor- 

 sal spine highest, a little more than 1.5 times in head, the 

 sixth spine separated from fifth by a wide interspace, all the 

 spines with elongate tips ; the second dorsal elongate posteriorly, 

 the central and posterior rays longest but the last two shorter, 

 about 0.6 of head or 1.64 times in head ; the anal angulate pos- 

 teriorly, gradually increasing in length from the front back-
