8 LOPHOBRANCHII. 



examples, two of them males and three females, have the lower 

 breast-spine forked, which is not the case with a larger specimen 

 in a dry state. The high dorsal exhibits two black bands. 



It inhabits the seas of Japan, and specimens exist in the Ley- 

 den Museum.

p. 16. f. 2. 

 Hippocampus brevirostris, Temm. et Schl. Faun. Jap. (partim). 

 Hippocampus fasciatus, Kaup. 



Diagn.—The pedestal of the occipital coronet and the snout 

 are short. The body has ten rings. 



JJescr. — This species is distinguished by the number of its 

 body-rings. The nasal projection is more prominent than in 

 brevirostris and japonicus. A small spine is situated before the 

 larger orbital one. The body is likewise higher than that of 

 brevirostris. The 2nd, 4th, 7th and 10th body-rings have more 

 prominent knobs, while on the tail it is the 3rd, the 8th and the 

 12th which have the longer knobs. A blackish band crosses the 

 7th and 8th body-rings, and there are 6 or 8 black cross-bands 

 on the tail. The dorsal fin, less high than that of brevirostris, 

 equals in height the length of the space between the fore border 

 of the orbit and the end of the snout. 



I know only one specimen, which is a female, and measures 

 2? inches from the coronet to the point of the tail. 



It inhabits the seas of Japan, and the Leyden Museum owes 

 its specimen to Dr. Von Siebold. 



4. Hippocampus Lichtensteinii, Kp. 



Diagn. — The occipital coronet is a roundish elevated knob, 

 with short spines before and behind. The short dorsal is 

 placed on the last two body-rings. 



Descr— Of this species I know only three young females, 

 which are in the Berlin Museum. It has a resemblance to bre- 

 virostris, but is easily distinguished by the diagnosis. The head, 

 gill-plates, and under-piece of the snout are warty, and some 

 warts exist on the sides of the body. The snout measured from 



* This name was bestowed by Bleeker in honour of a young Dr.
