This being a dead shell has lost the brilliancy of the enamel. The 

 teeth or folds at the posterior part of the inner and outer lips form 

 a very distinct canal. The columella is tortuous and turned back- 

 wards, and the notch is seen at the back like the canal of a Buc- 

 cinum.

 lip. Found on small plants in the island of Zebu. 



The following paper, entitled "Descriptions of four species of 

 the genus Chiton, brought by H. Cuming, Esq. from the Philippine 

 Islands," also by Mr. G. B. Sowerby, jun., was then read : —

 The few specimens of this shell which have been brought in fine 

 condition present an appearance of exquisite finish and great beauty, 

 both in sculpture and colouring. They were found in the crevices 

 of rocks at low water.
