This genus is at once distinguished from all the other Gorgonice 

 that I have seen, by its thin, smooth, skin-like bark studded with 

 sandy more or less raised wart-like cells, which on the thick stem are 

 numerous all round the surface, scarcely raised, while on the thinner 

 branchlets they are further apart, and form prominent wart-like 

 cells. 



The axis is olive-brown, formed of concentric laminae, which often 

 show a space between them at the fractures. When the bark is soaked 

 in potash it is ratber thick and flesh-like, and the cells are surrounded 

 with a single series of rather regularly disposed, nearly equal-sized, 

 angular, sand-like, transparent particles, forming a sheath to the 

 polype. 



The tentacle of the polypes, when examined in this state, are 

 thick, conical, and simple, without any indication of the pinnate tu- 

 bercles which are to be seen in the living Gorgonia, according to the 

 observations of most naturalists. 



I only know of a single species of the genus, which was purchased 

 of a dealer in natural history at Liverpool, without any habitat. 



Sarcogorgia phidippus. (PI. VIII.) 



2. Subergorgia. 



Coral furcately branched, rather compressed, with a continued 

 sunken groove up the middle of each side. Cell rather prominent, 

 convex, in two or three rather irregular series up each edge. Axis 

 pale brown, wart-like, formed of rather loosely concentric fibrous 

 laminae, containing a large quantity of calcareous matter, and effer- 

 vescing with muriatic acid. The bark when dry is rather thin, 

 smooth, hard and granular within. 



Stjbergorgia suberosa. 

 Subergorgonia suberosa, Esper. t. 49. 



This genus, and the genera Junceella, Ctenocella, and Gorgonella 

 of Valenciennes, should be arranged with Corallium under the family 

 Coralliidce, characterized by having a calcareous axis. 



0. Description of a Rabbit said to be found on the Hima- 

 layan Mountains. By A. D. Bartlett. 



(Mammalia, PI. LVI.) 



This animal is smaller than the domestic Rabbit, being shorter 

 and more compact ; its body is pure white, the nose, ears, legs and 

 tail are of a dark brownish-black, the eyes dark red. 



The fur is much shorter and more nearly equal in length than in 

 the common Rabbit. The young are perfectly white all over until 

 thev are five or six weeks old, at which time the nose and tail begin
