502 A COLLECTION OF FISHES FROM SUMATRA. 



of front rim of orbit. Interorbital space narrow, triangular, angle forming a little 

 in front of eyes. 



Gill-opening small, lateral, opening upward, high and close to nape near 

 nuchal keel. Coronet high, its upper surface concave, with two lateral and one 

 posterior tubercles, and also an elevated prominence springing from ridge in front. 

 Below latter, on each side of head, a round tubercle. Interorbital space with 

 each side of triangle continued as bony ridges till over middle of eye, where 

 they each form a round supraorbital tubercle. Shoulder girdle with three large 

 round tubercles. Bones on side of head, especially opercles, with fine radiating 

 stria?. Rings with concave surfaces, without spines, and with few rounded tuber- 

 cles, best developed on ridges of first ring, lower lateral ridges of trunk, and first 

 four or five of tail. None distinctly enlarged at regular intervals. 



Fins small, with simple rays. Dorsal rather low, beginning on middle of 

 tenth ring and then extending on to second caudal ring- near its posterior margin. 

 Anal small, short, on first caudal ring. Pectoral with a broad base, rays rather 

 short. 



Color in arrack dark brown, more or less indistinctly mottled with paler. 

 About five deep brown oblique cross-bars on side of snout. Several oblique deep 

 brown cross-bars on side of head. A deep almost blackish-brown band along 

 median compartment of spaces on side of trunk from base of pectoral to tail. Body 

 marked everywhere with numerous minute whitish dots. Fins pale, their bases 

 dark, especially that of dorsal. 



Length, measured from top of coronet to tip of extended tail, 5^ inches. 



Type No. 27,409, A. N. S. P. Padang. 



One example. This species is close to Hippocampus kuda Bleeker,^ which has 

 also been recorded from Priaman and Sibogha,^ and with which it may prove identi- 

 cal. However, it has one more dorsal ray, and the color is entirely different from 

 that given in the original description. M}^ example also has more caudal rings. 

 The Japanese example placed by Messrs. Jordan and Snyder^ with H. kuda may 

 still be different. It differs from my specimen in such points as its agrees with 

 Bleeker's, though its coloration is difierent from either. Hippocampus kamphylo- 

 trachelos Bleeker'' is the only other species known from Sumatra. It differs in 

 having twenty dorsal rays.
