specimens of them. The form of the abdomen of the spurious females is trigo- 

 nate in all the Portuni, but in P. sexdentatus the joints are arched on the side, 

 and constricted at the apex and base ; in Oxypode and Grapsus, differing from the 

 former, it is wider than the half of the breadth of the sternum, while of a ge- 

 nuine female it occupies the whole breadth, and the apical joint is trigonal not 

 dilated. The ovigerous appendages, or, as their use would warrant us in calling 

 them, the spurious feet, are fringed with long hairs in the females, but on the con- 

 trary in the neuters they are either smooth or very shortly hairy. The organs of 

 the body agree mostly with those of the females, but Portunus miles offers a dif- 

 ference in the claws, and .P. truncatus both in the claws and front W- De Haan

Arvicolce. — M. Edm. de Selys-Longchamps has published a short monograph 

 of the species of Arvicola found in the vicinity of Liege, and has given the cha- 

 racters of two species which he considers new and distinct. We add the de- 

 scriptions in his own words, to serve for comparison with the species of Britain.

Bones of the Camel found in a fossil state — M. de Blainville has announced 

 to the Royal Academy of Sciences at Paris, that he has learned from an indivi- 

 dual who has lately returned from India, that the fossil remains of the camel have 

 been found in the deposits of the lower ranges of the Himalayan mountains. 

 The remains alluded to consist of a cranium, which was found in a very hard 

 sandstone about two miles from Ramghur, and six from Pingon. This head, 

 almost entire, appears to have belonged to the Dromedary, or single-humped 

 camel. There has been also discovered in the same locality, the anterior part 

 of the head of an animal intermediate between the Anoplotherium and Paleo- 

 therium of the Paris Basin. And the tooth of a species of Mastodon, allied to
