of a brownish black, and shaggy, about four or five inches long ; 

 but, on the under parts, of an orange rufous colour : the muzzle 

 black. This individual was killed at the foot of the Tetuan moun- 

 tains, about twenty-five miles from that of the Atlas. It is consi- 

 dered a rare species in that part, and feeds on roots, acorns, and 

 fruits. Does not climb with facility ; and is stated to be very dif- 

 ferent-looking from any other Bear. The skin, like that of the ' She- 

 rif al Wady,' was attempted to be preserved, but unfortunately met 

 with the same fate." 



Dr. Lhotsky then read his paper " On Animal Tuition and Ani- 

 mal Hygiene." 



In the first part of this paper the author makes some observations 

 on the food of animals, and especially with reference to the quality 

 and quantity given to animals in menageries. He next proceeds 

 with remarks upon their abode, dens, cages, &c, the importance of 

 cleanliness, and upon their tuition. 



August 24. — R. C. Griffith, Esq., in the Chair. 



Mr. Westwood read his paper entitled " Descriptions of some Co- 

 leopterous Insects from Tropical Africa belonging to the Section 

 Heteromera." 



The insects comprised in this paper are of extreme rarity, and are 

 the giants of the family Tenebrionidce, constituting the genus Chi- 

 roscelis and other allied groups; some of them, however, appear to 

 lead to Lagria in their metallic colouring, &c.
