at the upper part of the root of the pectoral fin, and a third at the 

 lower part of the root, spreading on the gill-membrane. Near the 

 lower part of the root of the pectoral is a faint trace of a fourth brown 

 spot. The membranes of the fins are of a very pale bluish green, 

 minutely dotted with brown ; those of the dorsals, particularly the 

 second, with 3 or 4 indistinct series of blackish spots, and a few similar 

 on the caudal membrane. The rays of the anterior dorsal have 2 or 3 

 series of brown spots. Iris pale greenish silvery, minutely dotted 

 with brown.

A single individual observed differs from Gobius elegans* found in 

 Vanikolo, New Guinea, Java, and Bombay, in having one soft ray less 

 in the 2nd dorsal and anal-fins ; and slightlyi n colours, which differ- 

 ences however appear not sufficient to constitute a distinct species.

 abdomen white ; the back with 5 large, distant, brownish spots ; 5 

 similar on the sides, the latter disposed beneath the intervals of the 

 former. The rays and membranes of the dorsal and caudal fins with 

 brown spots distributed in transversal series, which, however, are fre- 

 quently very indistinct, and in some scarcely perceptible. One or two 

 brown spots appear in some at the root of the pectoral fins, the 

 membrane of which and of the ventral and anal fins is whitish. The 

 lower half of the anal and caudal membrane is blackish in some indi- 

 viduals. Iris golden, in some dotted with black.
