been anticipated in the January (1855) issue of Proceedings of 

 the London Zoological Society, and must yield to the names 

 there given by Dr. Pfeiffer. 



A. Wheatleyi Nob. is A. vidua Pfeiffer. 

 A. oviformis Nob. is A. Soioerbyana Pf. 



As the investigation of this genus is understood to be still in 

 progress by Dr. Pfeiffer, a delay in publishing a synopsis is 

 demanded, until he shall have completed his examination ; 

 when I propose to give as complete a work upon the subject, 

 as a five years' study, and my voluminous notes upon the shells 

 and animals of this genus, will permit. 



XXI. — Notes on certain Terrestrial Mollushs which inhabit the 

 West Indies. 



By T. Bland. Head June 4 and Oct. 22, 1855. 



I. Ok the Occurrence of Pup^ bicolor Hutton in the 

 Island of St. Thomas. 



Shortly after communicating to the Society Mr. E. J. Shut- 

 tleworth's Catalogue of the Terrestrial and Fluviatile Shells of 

 St. Thomas (Ann., Vol. iv., p. 68), I received another species, 

 which had just been discovered in that island, viz. Pupa bico- 

 lor Hutton. 



A dead shell was found there in February, 1854, by one of 

 the family of Mr. A. H. Ei'ise, and a considerable number of 

 live and dead specimens have since been collected in the same 

 locality, near the town, in "Berg's Garden" by the "Gut" 

 which runs behind the Protestant Episcopal Church.
