to the west, whose snows must have nourished enormous glaciers ; 

 and he concludes by stating that Professor Agassiz, during an inde- 

 pendent tour, arrived at similar conclusions respecting the mode by 

 Vihich the Shap boulders were distributed. 



ZOOLOGICAL SOCIETY. 

 August 25, 1840. — W. H. Lloyd, Esq., in the Chair. 



Two papers were read, in which the authors resume the descrip- 

 tions of the Shells collected by H. Cuming, Esq., Corr. Memb., in 

 the Philippine Islands, who exhibited specimens in illustration of the 

 papers. 



The first of these papers is from W. J. Broderip, Esq.

This variety is sometimes yellowish, and the three bands on the 

 bodj'-whorl are nearly uniform chestnut.

Legit H. Cuming in sylvis. 



Mr. Cuming informs us that the animal of this elegant shell, 

 which in the form of the spire and the distribution of the colouring, 

 though not in the colouring itself, reminds the observer of Achatince 

 fasciata, emarginata and virginea of Swainson (Zool. 111.), varies 

 much. In all the varieties the broadly expanded lip is white, both 

 above and below, and the bands of the body- whorl terminate 

 abruptly upon its upper part, so that the shell almost looks as if the 

 wide white lip had been added to some of the Riband Achatince, 

 for varieties of which some of the young might be taken by a cursory 

 observer. The animal was ash-coloured, darker above. General 

 length of the shell about two inches ; width of body-whorl from |ths 

 to ^ths of an inch.
