478. Hippocampus subcoronatus, sp. n. Plate XX. fig. 4. [609 a.] 
This species is evidently closely allied to H. coronatus, 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 tvith 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.
