Considerable difference is shown in the shell from the 

 species figured by W. G. Binney as of this " subgenus 

 of Stenogyra,"" and it is very doubtful if it is related to 

 it, or to the family Stenogyridct, which has a jaw of one 

 piece, which this certainly has not. Its dissection has not, 

 however, been completed, and it seems externally to have 

 more relations with Cylindrella.

 (The latitude of Punta Arena there given as 25'^ 30' 

 should be 23° 30'.) 



This subspecies being most common at a high eleva- 

 tion, its differences from the lowland type may be due to 

 the same environing influences that have produced the 

 stunted form of Cohcmna. The occurrence of a few 

 specimens near sea-level may be caused by mountain tor- 

 rents having washed down a few, which have, perhaps, 

 established a temporary colony there.

Since the article above referred to was pubHshed, in 

 which I showed the close resemblance of this to B. A\in- 

 l!.s/W. G. B., I have seen the plate and description by 

 C. & F. in the MoUusques du Mexique, and there is cer- 

 tainly much reason to consider their B. gabbi as not more 

 than a subspecies at most of B. Xanttisi, of which they 

 merely copy Binney 's figure and description. While
