the broad and projecting sulcus at the anterior portion of the co- 
lumellar groove; and the convergence of the anterior extremities, 
rendering the channel so much narrower than in piperita. 
13. Cyprza nivea.—The shell described under that appellation 
by Gray, the original type of which, pierced with its two holes, is now 
before me, is a white variety of Cyprea turdus :—vide Gray’s Mo- 
negraph (Zool. Jour, i. 511). The figures, however, of Cyprea 
nivea of Gray, in Sowerby’s Conch. Illus. and in Reeve’s Conch. 
Iconica, are representations of the Cyprea oryza of Gray (Zool. Jour. 
ili. 369); this same error seems to pervade in the arrangement of 
most of the collections I have seen. The Cyprea nivea figured in 
Wood’s Supplement to the Index Testaceol. is a young Cyp. Hum- 
phreysii of Gray. 
14. Cyprza Propucta.—I am able at length to refer concho- 
logists to other specimens of this species than that described by 
me December 22, 1836, in these ‘ Proceedings,’ which have been 
brought to this country by Capt. Sir Edward Belcher, and collected 
during the voyage of H.M.S. the Samarang. They are distributed 
into the cabinets of Miss Saul, Messrs. Cuming, Gaskoin, &c. The 
original shell, the type of this species, is well-represented in Sow- 
erby’s Conchological Illustrations, fig. 155 ; in Reeve’s Conchologia 
Iconica, pl. 24, fig. 137; and in Kiener’s Species général, et Icono- 
graphie des Coquilles vivantes, fol. 53, figs. 5 and 5 :—this last is 
copied from Sowerby. 
June 27, 1848. 
William Yarrell, Esq., V.P., in the Chair. 
Lord Auckland communicated through the Secretary a letter which 
he had received from Lieut.-Col. Butterworth, the Governor of Sin- 
gapore, announcing his desire to present to the Society a Black 
Leopard and a Tree Kangaroo ( Dendrolagus inustus, Miller), which 
he intended to transmit to England by the first opportunity. 
A letter was read from T. S. Boileau, Esq., H-E.1.C. Civil Service, 
in which he informed the Secretary of the safe arrival of a living pair 
of the Indian Wild Hog and an Owl (Bubo bengalensis), which he had 
brought from Madras expressly for the Society’s acceptance.
