specimens, aud the Museum of the Peabody Academy of Science, at 

 Salem, Mass., numerous examples of this species. In connection with 

 the above measurements, it should be borne in mind that the contrac- 

 tion caused by the alcohol materially affects the proportions; the ani- 

 mal, when alive, is undoubtedly very much longer and somewhat 

 broader tban above stated. 



The few species known inhabit tropical or semi-tropical climates; 

 the form above described is quite distinct from V. Floridana^ which is 

 also found in Nicaragua (Eastern Department), where it was collected 

 ''under stones, Javate, Chontales ; probably the same species, but 

 twice the size of Toro Kapids." ( Yu'e paper "On the Land and Fresh- 

 water Shells of Nicaragua, by Eai^'^i Tate," in American Jonriud of 

 Conchology, Vol. Y, pp. 151-162.) 1 le "Toro Kapids" specimens of 

 Mr. Tate's collection possibly belong to the species herein described, 

 but it is hardly i^robable that the w II marked differences between the 

 latter and Y. Floridana could have escf )ed detection. (Stearns.)
