106 THE NAUTILUS. 
discus lineatus, Strobila labyrinthica, Vallonia pulchella var. costata, 
Limax campestris and Bulimulus dealbatus, also Pupa fallax and 
rupicola 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?—Franxk J. Forp, 
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 conveva 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 Say, 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. 
humphreysii 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.
