Eberhard,Ernst. U eber die Schneckenzungen. [On the tongues 
of Snails.] Programm der Bealschule zu Coburg, 1865, 
4to, with 5 plates. 
Contains descriptions and figures of the buccal organs of Helix 
pomatia in different states of protrusion, in connexion with one 
another as well as isolated (pi. 1), and original descriptions and 
figures of the so-called teeth of the tongue or radula, taken from 
fifty-four species of Gastropoda and one Cephalopod. We shall 
mention subsequently only those species which are not figured 
in the paper of Loven (Qilfversigt af K. Yet. Akad. 1847) or 
in the standard work of Troschel. Of some of the snails, only 
the generic name is given in the explanation of the plates and 
in the text ; the Becorder is able to supply the specific names of 
a few of them through a private communication from the author,

The tentacles are stated to be the organs of smelling in water- 
snails as well as in land-snails ; this is proved by experiments and 
by their analogy with the smelling-organs of fishes, — We have 
not seen this dissertation.
