H LOPHOBRANCHII. 



height as the last five body-rings do in length. Only one 

 ring of the body assists in supporting the dorsal fin. " The 

 soft parts of the body show rows of light-coloured specks 

 on a dark ground. 



Descr. — A dried female specimen, sent from Algiers by M. 

 Guichot to the Paris Museum under the appellation of H. lon- 

 girostris, has much likeness to that species, as well as to H.punc- 

 tulatus. The distinctive character of the latter consists in the 

 7th and 10th body-rings being the highest, and in the dorsal fin 

 standing on three rings, of which one" only is caudal. H. longi- 

 rostris, on the other hand, may be discriminated by the 8th 

 ring in the females, which is the highest, being as high as the 

 last five body-rings are long. Its soft skin has, moreover, little 

 warts which are wanting in'H. algiricus. The Parisian specimen 

 of H. algiricus is almost 5 inches long. 



11. Hippocampus punctulatus, Kp. 



Diagn. — Length of the snout equal to the distance between the 

 front of the orbit and the edge of the breast-ring. Tn the 

 female it is the 8th body-ring which is as high as the last 

 six body-rings are long. Two of the rings on which the 

 dorsal stands, belong to the tail. 



Descr. — Of this species I know only a solitary example, 

 which belongs to the Ley den Museum, and is a female. It bears 

 much resemblance to H. longirostris, but is distinguished from 

 it, 1st, by a shorter snout ; 2nd, by the head being at the lower 

 spine of the breast-ring somewhat higher, and by the outline of 

 the breast and belly being more protuberant. In females of H. 

 hngirostris these parts are more nearly equal in height, and the 

 7th and 10th rings are almost of the same altitude. The soft 

 parts are blackish-brown dotted with white; the gill-plates have 

 black specks and stripes of white points.

Hippocampus mannulus, Cantor, Malay Fishes, p. 1370. t 1 1 

 f. 1(?). 



Diagn.— The snout equal in length to the space between the 

 front of the orbit and the edge of the gill-plate. The spines 

 on the upper rim of the orbit and the one on the lower piece 

 of the breast-ring, sharp-pointed and recurved. Dorsal fin 

 as long as the snout.
