H. Barclay ana, Pfr. Monogr. Hel. Viv. p. 118. no. 305. 



On an examination of this Mauritian shell in Mr. Cuming's 

 collection, it struck me (from my observation of the adult and 

 young of one of the smaller Pupa of the Isle of France while 

 alive in their native haunts, and which, at first sight, appeared 

 to belong to different genera) that this supposed Helix was the

 around Curepipe in the same island. Mr. Cuming's stores 

 affording specimens of Pupa Pagoda in different stages of growth, 

 a comparison was instituted, which left no doubt of the specific 

 identity of the two separated shells. Helix Barclay ana will there-

H petrosa, Hutton, J. A. S. vol. iii. p. 83 (Pfr. no. 114). 

 This species must be erased from the catalogue. Capt. Hut- 

 ton's specimens were H. (Nanina) vitrinoides, Deshayes, and were 

 imperfectly described by him in 1834. 



H. (Nanina) fragilis, Hutton, J. A. S. vol. vii. p. 216, 1838 

 (Pfr. no. 89). 



This is another species which Pfeiffer has not seen. . In the 

 note which I took of the shell when I had an opportunity of in- 

 specting it, I find recorded " last whorl ventricose, slightly an-
