in groups, the arrangement of which recalls that of the compartments 

 of an orange. 



In the pedal or abdominal ganglion, which is composed of several 

 medullary nuclei, there are likewise very marked diiferences of 

 structure. In a longitudinal section of one of the sides of the gan- 

 glion (in the Helix) four groups of pyriform cells are seen occupying 

 all the upper and posterior region. In the lower region there is a 

 group of small round cells. If a transverse section be made in the 

 upper region, these groups of cells are seen separated by thick par- 

 titions of conjunctive tissue. Of these groups, the two lateral con- 

 sist of small round cells, all communicating by numerous cylindraxes. 

 The median groups are composed of cells three or four times as large 

 as the preceding, and form a very regular circle. At the centre of 

 this circle there is a cell, the diameter of which is three or four times 

 that of those forming the circumference ; to the latter it sends off 

 numerous processes. 



The peripheral nerves are formed of very delicate tubes, having in 

 their walls nuclei similar to those which are observed in the higher 

 animals in the embryonal state. The mode of their termination in 

 the muscles is remarkable. The nervous element, on arriving at the 

 muscular fibre, loses its proper wall, and the cylindraxis alone pene- 

 trates the muscle, dividing into two very slender filaments. These 

 take opposite directions, each traversing one-half of the muscular 

 fibre, on arriving at the extremities of which they terminate in very 

 fine points. 



To show the cylindraxis in the interior of the muscular fibre, and 

 prove that it does not creep along its surface, the author made trans- 

 verse sections of muscular bundles, and ascertained that the cylin- 

 draxis occupies the centre of each fibre. In some, two cylindraxes 

 are observed, one of which is finer than the other. — Comptes Rendus,

On the Chanco or Golden Wolf {Cams Chancp). 

 By Dr. J. E. Gray, F.R.S., &c. 



Lady Augustus Hervey has kindly presented to the British Mu- 

 seum a fine specimen of the skin of a Wolf, which was shot by her 

 brother, Lieut. W. P. Hodnell, of H.M.'s 54th Regiment, in Chinese 

 Tartary. It is a very showy animal, rather larger than the common 

 European Wolf. 



Fur fulvous, on the back longer, rigid, with intermixed black 

 and grey hairs ; the throat, chest, belly, and inside of the legs pure 

 white ; head pale grey-brown ; forehead grizzled with short black 

 and grey hairs. 



Ilab. Chinese Tartary. Called Chanco. 



The skull is very like, and has the same teeth as, the European 

 Wolf (C Lupus). The animal is very like a Common Wolf, but 

 j'ather shorter in the legs ; and the ears, the sides of the body, and 

 outside of the limbs are covered with short pale fulvous hairs. 



The length of its head and body is 42 inches; tail l."! inches. —
