\_C{onella^ Zua Inhricoides (Stimp.). An attentive examination and com- 
parison of many specimens from several different localities in Europe, and from 
Ohio, New York, Massachusetts, many places in Maine, &c., has not as yet 
brought to light any satisfactory characters by which to distinguish this species 
from its European representative \Juhrica, Miill.]. A few differences which 
seemed to hold good in a majority of cases are mentioned. Morse, Journ.

Pupa. The buccal plates of Lcucochila pentodon and corticaria (Say), Pu- 
pilla hadia (Adams), Isthmia ovata (Sa)^) and goiddii (Binney) are described 
and figured b}'^ Morse, 1. c. pp. 36-38. They are very dissimilar : in L. cor- 
ticaria only with slight striae in the middle and a middle projection, lateral 
ends pointed, like that of Ilyalina ; in P. hadia with numerous longitudinal 
striae on the upper half only ; in I. goiddii with transverse and longitudinal 
striae ; in I. ovata strongly curved, with few striae ; in L. pentodon irregu- 
larly wrinkled longitudinally, the wrinkles forming slight projections in the 
cutting edge. The teeth of the radula in all these species are figured on plate 
10, and much more similar. In hundreds of specimens of Pupa hadia, col-
