16 MR. H. ABAMS ON NEW SHELLS. [Jail. 9, 



first discovered by myself, several years since, among large boulders 

 of blue basalt, about halfway up the Montagne-au-Riz, on the left- 

 hand side of the road to Moka ; and subsequently I found a few-

 by exposure. During the remainder of my residence at Mauritius 

 no other specimen was met with ; but since my return to England, 

 the one figured, which is in better condition than those I collected, 

 was obtained on the same spot by E. Dupoiit, jun., Esq., and sent 

 to me." — D. Barclay.
