L.OPHOBRANCHII. 37 



Descr.— This species is distinguished, by its combined cha- 

 racters, from the others which inhabit the seas round the Cape 

 of Good Hope. The prominent line on the snout is not toothed, 

 and the lateral line is interrupted. Thirty-one rays exist in the 

 dorsal fin, which is somewhat longer than the head. Colour a 

 smutty yellowish-brown, irregularly speckled. A female 6"2fi 

 inches long, has a snout 028 inch long, the tail 3"66 inches, and 

 the dorsal fin 0'73 inch. In a smaller male of 508 inches, the 

 egg-pouch measures 1"58 inch. Its predominating colour is 

 brownish with smutty yellowish specks. 



A male and a female specimen, procured by M. Horstock at 

 the Cape, exist in the Leyden Museum ; and I have named the 

 species after the Director of that Museum out of gratitude and 

 esteem. 



8. Syngnathus brevirostris, Hempr. et Ehrenb. 



Diagn. — Snout, measured from the fore-border of the orbit, 

 as long as the distance between the hinder border of the 

 orbit and the edge of the gill-cover ; it is furnished with a 

 keel, which runs on the same level with the forehead. Hind- 

 head somewhat elevated. Seventeen rings before the dorsal 

 fin, which stands on 8 rings, two of them belonging to 

 the body. This fin has 30 or 31 rays, and equals the head 

 in length. 



Descr. — This species comes near S. Agassizi and S. Murcena, 

 both of which have a longer and more slender snout, and a dorsal 

 fin shorter than the head ; also a more sudden descent of the 

 forehead to the snout. The colour is reddish, finely dotted with 

 black and lighter points. A young female shows narrow clear 

 cross bands, separated by wider intervals. The inner side of the 

 scales over the egg-pouch of the male is reddish with white 

 specks, and the skin of the pouch is flesh-coloured. Dorsal fin 

 diaphanous, and speckled with black at the base between its rays. 

 A male having a total length of 465 inches, has the head - 55 

 inch long, the snout 024 inch, the body, up to the anal ring, 

 126 inch, the dorsal fin 0-55 inch, and the egg-pouch l - 38 inch 

 long. 



There are two specimens in the Berlin Museum, which were 

 procured at Trieste by Ehrenberg and Hemprich.
