the raclula of E. complicata, quadridentata [= dupuyana (Crosse), conica 
and stylodon (Martens)]. Median teeth of the radula wanting in some 
species, or present only in the younger part of the radula in E. insignis, 
well developed in E. complicata. Structure of male organ invaginated in 
a complicated manner. JB. mal. Ges. v. pp. 62-69, with woodcuts.

OXYGNATHA. 
G. PfRffer publishes some interesting observations on the anatomy of 
this family generally, drawn from numerous special observations ; he 
adopts for it the name Vitrinacea^ characterized as follows : jaw smooth, 
often with a median projection ; lateral teeth of the radula never with 
more than three cuspids, marginal teeth elongate, one or two cuspidated ; 
the second cuspid of the latter corresponding to the outer one of the 
median and lateral teeth. He admits three subdivisions 
1. Naninidce : a mucus caudal pore ; genital orifice very near the left 
feeler; outer cuspid of the lateral and marginal teeth gradually 
approaching the tip, when examined in the direction from the median 
line to the lateral margin of the radula. 
2. ZonitidcB : a mucous caudal pore ; genital orifice far behind the left 
feeler ; outer cuspid of the lateral teeth gradually approaching the 
base and disappearing very soon, marginal teeth therefore unicuspi- 
date. 
3. Vitrinidce : no mucous caudal pore. 
The underside of the foot in the Naninidce is either simple oi^ tripartite, the 
lateral parts being transversely striate. Cervical and shell lobes of the edge 
of the mantle are usually present ; the outside of the shell- lobe, rough and 
coloured, is continuous with the soft and pale inside of the mantle itself, 
as the lobe is reflected over the shell ; the right cervical lobe is larger 
than the left, and often extends (m the left side, being also sometimes 
subdivided. The different modifications of the genital appendages and 
radula are discussed and exemplified. JB. mal. Ges. v. pp. 251-276. .
