NOTE ON THE GENUS BOURCIERA. 



By Thos. Bland. 



Bourciera was described as a genus of the family Cyclostomacea, 

 in 1 85 I, by Dr. Pfeiffer, and similarly treated in his Monographia 

 Pneumonopomorum Viventium (1852) also in the first (1858) and 

 second (1865) Supplements. In the last he refers to the assertion 

 of Troschel that Bourciera from the character of the dentition 

 belongs rather to the JJeliciitacea. 



Paetel (Catalog. 1873) places this genus in the subfamily 

 Realma. 



Pfeiffer in his third supplement to the Monograph (1875) 

 deals with Bourciera as " Subfamilice ambiguae genus." 



The close alliance of Bourciera with the family Helicinacea is 

 shewn not only as regards animal by the dentition, but as to 

 .shell by the absorption of the internal septa of the whorls, as in 

 Stoastoma, Trocliatella, Lucidella^ Helicina, and Alcadia* ; the 

 existence of this character in Bourciera has not hitherto, I believe, 

 been published. 



NOTE ON HELIX PULCHELLA, Mullen 



By Henry Hemphill. 



It may be of interest to some of the readers of the Journal 

 to know that the small Helix pulchella, Mlill., which is found 

 throughout Europe, Siberia, Madeira. Azores, &c., also has a wide 

 range in North America. It is credited to Canada East, Florida, 

 Nebraska, and Kansas. In the Spring of 1861 I had occasion to 

 visit the White-Pine Mining district in Nevada, and at an eleva- 

 tion of 8000 feet I found it quite abundant, associated with Pupa 

 Arizonensis, Gabb, and Viti-ina Pfeifferi, Newc. I also found it 

 quite numerous 75 miles south of White-Pine district, on a rocky hill 

 side at a much lower elevation. In 187 1 1 visited Idaho territory and
