LOPHOBRANCHII. 13 



is nearly allied to //. comes, but comes has a longer snout and 

 larger spines on the head and body when young. It has also a 

 resemblance to H. moluccensis, but the soft parts of the body and 

 tail are furnished with small warts, and the snout is proportionally 

 somewhat longer ; the coronal pedestal is a little shorter, and 

 the tips of the coronet less projecting. Much variety occurs in 

 this species also. A male sent to the Paris Museum from Mar- 

 tinique by M. Richard, is yellowish-brown with dark brown 

 specks encircled bv small white warts. A dark brown spot on each 

 ring forms a row along the lateral line. This individual measures 

 5:f inches in length, and its height at the 10th ring is equal to the 

 length of the last six body-rings. A female from the same island 

 is discoloured bv maceration in alcohol, but still retains traces 

 of irregular clouded transverse bars : one of them on the /th and 

 8th ring, another near the dorsal fin, and a third on the 5th and 

 6th tail-ring. Another individual from the same quarter, sent by 

 M. Ple'e, is dark greenish -brown with black specks, and marbled 

 markings on the 1st, 4th, 7th and 8th body-rings. A female 

 sent from St. Lucie by M. Bonnesart is besprinkled with dark 

 round spots, encircled by fine white dots ; some irregular cross 

 bands on the body and tail. On the end of the upper border of 

 the orbit there is a small protuberance. This one is nearly 

 5 inches long, and is 0'71 inch high at the 7th riug, where the 

 height equals the length of the last four body-rings, as in the 

 female from Martinique. 



9. Hippocampus bicuspis, Kp. 



Diagn. — The spine that precedes the coronet and the one over 

 the nostril forked. 



Descr. — I am acquainted with only a very young female 

 specimen, which was sent from Goree to the Paris Museum by 

 M. Rang. It has 11 body-rings, of which the 1st, 4th, 7th and 

 11th have the bigger spines and projections. Three rings sup- 

 port the yellowish back fin. The body is very slender, and at 

 its greatest breadth does not exceed in width the length of the last 

 four body-rings. Two traces of dark cross bars upon the snout. 

 Colour yellowish-brown, darker on the back and tail. 



10. Hippocampus algiricus, Kp. 



Diagn.— Snout equal in length to the distance between the 

 fore-border of the orbit and the edge of the breast-ring. In 

 females the 7th and 10th body-rings measure as much in
