It contained ten oblong minute white eggs, 4-g-ths of an inch long 

 by T Vths in diameter. It was found in the fork of a branch of the 

 Mimosa Arabica. 



The nest of the Orthotomus Bennettii was lodged in the cavity 

 formed by sewing the edges of two leaves together : the nest itself 

 also was attached to the leaves by threads passing through the leaf 

 and the bottom of the nest, and there were appearances of the end 

 of the thread being knotted outside. The nest is composed of very 

 delicate fibres of Indian Hemp and grass. It contained two minute 

 oblong crimson eggs, ^Vths of an inch long by Wths wide. 



Col. Sykes also exhibited an egg of the fluviatile Tortoise of Duk- 

 hun, Trionyx Indicus, Gray. It is a perfect sphere, 1 T V inch in dia- 

 meter: the calcareous shell is of a peculiar alabaster-like white- 

 ness. He found seven eggs with shells in the oviducts, and twenty- 

 seven without shells, nearly of the size of the preceding, in one 

 specimen. He took occasion to mention that in the stomach and 

 intestines of another specimen of Trionyx, he found not only the 

 animals, but also angular fragments of considerable size of the shells 

 of some scores of large Uniones. 



A paper was read, entitled, " Description of some Species of 

 Chama : by W. J. Broderip, Esq., Vice-President of the Geological 

 and Zoological Societies, F.R.S., L.S., &c." 



The author commences by remarking that the shells of the genus 

 Chama appear to be subject to every change of shape and often of 

 colour which the accidents of their locality may bring upon them, 

 and that the distinction of the species must consequently be diffi- 

 cult, on account of their infinite variety. He then proceeds to de- 

 scribe those brought home by Mr. Cuming, and now in that gentle- 

 man's cabinet. The Shells referred to were exhibited in illustra- 

 tion of the characters and descriptions, under the following specific 

 names : Chama frondosa, pellucida, lobata, Pacifica, imbricata, pro- 

 ducta, corrugata, echinata, spinosa, and sordida. 



A Note by Mr. George Bennett on the Nasal Gland of the wan- 

 dering Albatross, Diomedea exulans, Linn., was read. It described in 

 detail the gland situated in that bird above the orbit, as observed by 

 the writer in 1832, and accorded with the account of it published by 

 him in the Appendix to his ' Wanderings in New South Wales,' &c. 

 It was illustrated by a drawing of his dissection of the head of an 

 Albatross, made specially with the view of tracing the excretory duct 

 of the gland, which he succeeded in doing for nearly two inches 

 under the external plate of the upper mandible, in a direction towards 

 the nostrils, but inclining slightly upwards, until he lost sight of it 

 among the cellular substance of the bone. The writer notices the 

 occurrence of a corresponding structure in other Birds, particularly 

 among the Natatores, and refers to Miiller for an account of the 

 gland as it exists, in or near the orbit, in species of every order of 

 Aves. 



A specimen was exhibited of a Kangaroo, recently brought from 

 New Holland, by Capt. Sir W. Edward Parry, R.N., and presented 

 by him to the Society.
