LOl'HOBRANCHII. 35 



the first of which is the anal ring. There are 1C rings 

 before the dorsal, and 13 if the anal ring be included. The 

 upper edge of the back continues on to the 2nd ring of the 

 dorsal, and the upper edge of the tail comes forward upon 

 the anal ring. 



»B" 



Descr. — The diagnosis shows us that this species is allied to 

 spicifer. The snout, which is a little recurved in its height, is 

 somewhat shorter than the head, and the belly is slightly acute. 

 Tail-rings 34. On the short dorsal there are three rows of 

 black spots, and a black speckling on the greyish ground-colour 

 of the caudal, whose border is lighter. On the seven specimens 

 discoloured by alcohol, belonging to the Leyden Museum, there 

 is a trace of a darker transverse bar on each ring, which is also 

 one of the characters of spicifer. The Paris Museum possesses 

 a male, in which the distinctly keeled belly is black.

5. Syngnathus flavescens, Kp. 



Diagn. — Snout half the length of the head, traversed up to the 

 mouth by a crest ; 12 rings before the dorsal, which stands 

 on 1 1 rings, three of them belonging to the body. Tail- 

 rings 37. 



Descr. — This species resembles S. Agnssizi, but has on both 

 sides of the head traces of a line in relief, which extends from the 

 orbit to the hind-head ; sunken lines on the middle shield of 

 the occiput, on the nuchal shield, and on the dorsal surface of 

 the pectoral ring, which parts are merely shagreened in Agas- 

 xizi.
