CARBONIFEROUS LAND SNAILS. 



Pufa vettista, Darwin, and Conuhts prisca, Carpenter, with egg of Pupa 

 vetnstatt\z whole considerably magnified. 



I published in 1880, in the Ameri- 

 can Journal of Science, a fragment of 

 what seemed to be a land snail, from 

 the Middle Erian plant beds of St. 

 John, New Brunswick (Strophia grand- 

 ova, figured above), but have mentioned 

 it with some doubt in the text. Mr. G. 

 F. Matthew has, however, recently 

 communicated to the Royal Society of 

 Canada a second species, found by Mr. 

 W. I. \Vilson in the same beds, and 

 which he names Pupa primava. It is 

 accompanied with a scorpion and a 

 millipede. Thus the existence of Land 

 Snails of the Pupa type in the Devonian 

 may be considered as established,
