A very good songster. These birds, although in deep moult (in 

 June), appeared to be pairing. One specimen was shot from the top 

 of a very lofty tree, the others much nearer the ground. In an ap- 

 parently young male the black extends across the forehead. 



October 25. — Williacn Yarrell, Esq., Vice-President, in the Chair. 



Prof. Owen exhibited a specimen of the Pearly Nautilus (Nautilus 

 Pompilius), animal and shell, obtained by Capt. E. Belcher, R.N., at 

 Amboina. Prof. Owen alluded to the fact of the specimen described 

 by him in 1832 having been detached from the shell, which was de- 

 stroyed in its capture, and to the analogies which had guidedhim in 

 determining the position in which he had restored the soft parts to 

 the shell, and figured them, in situ, in his memoir. Objections had 

 been made to this restoration by Mr. Gray* and by Dr. Grantf and 

 De BlainvilleJ, who were led by other analogies to believe that the 

 upper or outer lip of the shell must have crossed the back of the head, 

 insteadjof crossing the opposite side or funnel, as represented by 

 Mr. Owen. M. Valenciennes, who had subsequently received the soft 

 parts of a Nautilus, had adopted the position assigned to them in the 

 shell by Mr. Owen. 



The present example, in which the animal had been restored by 

 Capt. Belcher to its shell in precisely the same position in which it 

 was received by him, when recent, closely agreed with the descrip- 

 tion and figure in Prof. Owen's work§. The involuted spire of the 

 shell is covered by the dorsal fold of the mantle, and is lodged in 

 the concavity at the back of the muscular plate above the head. The 

 funnel rests upon the outer wall of the large chamber containing the 

 animal. 



A paper by G. B. Sowerby, Esq., Jun,, containing descriptions of 

 two new species of shells belonging to the genus Strombus, was then 

 read. The specimens were collected by the Society's Corresponding 

 Member, H. Cuming, Esq., in the Philippine Islands, and exhibited 

 by that gentleman to the Meeting.

A finely sculptured species resembling the well-known Str.fissw 

 rella, but rather more ventricose, with the edges of the posterior 

 canal free, rather short, and coiled at the extremity. The colour is 

 pale straw, with three brown bands across the body whorl.
