106 THE NAUTILUS. 



discus lineatus, Strobila hihyrinthica, Vallonia pulchella var. costata, 

 Limax campestris and BuUmulus dealbatus, also Pupa fallax and 

 riipicola from Kingman County, 60 miles west of Wichita. Is it in 

 any way remarkable to find so many species of Eastern and South- 

 eastern Shells so far West and North of this ? — Frank J. Ford, 

 Wichita, Kansas, in letter to Ed. 



Crepidula glauca vs. C. convexa. In the discussion of these 

 Crepidulas the fact seems to have been lost sight of that if identical 

 (as I have no reason to dispute) the name glauca has precedence 

 over conve.va in the original paper by Say in the Journal of the 

 Academy of Natural Sciences of Philadelphia. The names would 

 stand thus : C. glauca Say for the type form, and C. glauca var. 

 convexa Sny, for the high rounded form, if it be considered of even 

 varietal importance. — H. A. P. 



ScALARiA of the New Jersey Coast. Under the name of S. 

 angulata there have been included two species by most authors 

 and collectors. These have been separated and the differential 

 characters pointed out by Dr. Dall, in his great work on the 

 'Blake' Mollusks, who proposes for the more slender, elongated 

 one the name Scala sayana. This very form is, however, the true S. 

 humphreysll of Kiener, described and figured many years ago. The 

 synonymy of the two forms has become so confused that I give it 

 below in systematic order.
