inent, reddish brown ; wings large, external margin brown. Fe- 

 male (fig. 6) black, somewhat hirsute ; legs brown, ciliated ; head, 

 antennae and thighs, pale corneous. A large species. Hab. Pinus 

 mitis. 



6. A. pilosa : grey, with a short dense pile, which is wanting 

 upon the numerous circular black spots of the surface ; base of the 

 antennae and femora corneous ; feet and tibiae black, except a 

 small testaceous portion next the knee joint of the 2d and 3d pairs. 

 Perhaps Aphis salicis, Lin. as it occurs upon an exotic species of 

 salix. 



7. A. discolor : black, abdomen brownish yellow ; anterior

Dr. Binney reported that the Crustacean, committed to 

 him at a recent meeting, proved to he the female of Li- 

 thodes arctica, a species common to the northern parts of 

 Europe and the corresponding coast of N. America. 



It is the second specimen recorded as taken upon our shores. 

 It was taken from the stomach of a codfish near Nahant, and from 

 the fact of another specimen having been taken in the same neigh- 

 borhood, from the stomach of the same species, and both hardly 

 altered by the action of that organ, it may be reasonably inferred 

 that its habitat extends from Greenland to our own vicinity. Both 

 specimens were procured in the winter. The cast off shells have 

 never been noticed thrown up on our shores, while those of other 

 species are common. 



Mr. Perkins presented a specimen of Vegetable Tallow, 

 brought by him from Africa. 



Mr. Teschemacher remarked that he supposed it to be the Shea 

 butter, a substance which he had seen mentioned as collected by 

 Dr. Stanger on the late expedition to the Niger, and which is sup- 

 posed to be the inspissated juice of Bassia Parkii, specimens of the 

 dried fruit of which were lately presented to the Linnean Society 

 of London, by Mr. Smith, of Kew. Mr. T. has seen in a late pub- 

 lication that this plant has flowered in some of the conservatories 

 in England. 



This substance was referred for chemical examination to Dr. C. 

 T. Jackson.
