478. Hippocampus subcoronatus, sp. n. Plate XX. fig. 4. [609 a.] 

 Tbis species is evidently closely allied to H. eoronatus, Schleg.; but the occipital 



crest is much lower, and there are three spinous projections along each side of the 

 base of the dorsal. 



The length of the snout equals the distance from the hind margin of the orbit to the 

 edge of the gill-covers, the interorbital crest projecting above its upper margin. Orbital 

 and occipital spines well developed, simple. Occipital crest subtriangular, not quite as 

 high as snout, and terminating in a subpentagonal knob. Body with eleven rings ; the 

 first, fourth, and seventh have the spinous prominences rather stronger than the 

 others. Dorsal fin with eighteen rays ; it is situated on the last two rings of the body 

 and the two first of the tail. Caudal rings thirty-six in number, of which each 

 alternate one has the spines more prominent. 



Colour in a dried state. — Brown ; head variegated with yellowish. — Length 4 inches.
