This genus is at ouce distinguished from all the other Gorgonice 

 that 4 have seen, by its thin, smooth, skin-like bark studded with 

 saiidy 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 forra prominent wart-like 

 cells. 



The axis is oliTe-browii, formed of concentric laminse, which often 

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

 in potash it is rather thick and flesh-like, and the cells are sun-ounded 

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

 angular, sand-like, transparent particles, forming a sh^th to the 

 polype. 



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

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

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

 observations of most naturalists. 



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

 of a dealer in natūrai 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, 

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



pale brown, wftrt-like, formed of rather loosely concentric fibrous dt^* 

 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. 



SUBERGORGIA SUBEROSA. 



S^tb^^orgonia suberosa, Esper. t. 49. 



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

 of Valenciennes, should be arranged with Corallium under the family 

 Coralliidce, characterized by having a calcareous axis. 



6. Description of a Rabbit said to be fotjnd on the Hima- 



LAYAN MOUNTAINS. By A. D. BaRTLETT. 



(Mammalia, PI. LVI.) 



This aniraal is smaller than the domesfic 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 niuch shorter and more nearly equal in length than in 

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

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