248 REPORT—1843, 
Those who have given attention to the Testaceous Mollusca generally have 
hitherto been alluded to. The native land and freshwater species exclu- 
sively have been well studied by the Rev. Benj. J. Clarke, Mr. Edward Wal- 
ler, and the Rev. Thomas Hincks (late of Cork). Several other naturalists 
and collections might be named, but those enumerated are among the principal. 
The species added to our Fauna from the preceding sources and from per- 
sonal investigation, have been noticed in ‘ Additions to the Fauna of Ireland,’ 
published in the ‘ Annals of Natural History’ (vol. v. vii. xiii.); in vol. v. a 
deseription of Limneus involutus, and a contribution on the Mollusea Nudi- 
branchia and Moll. Tunicata will be found: in vol. vi. is a catalogue of the 
land and freshwater Mollusca. 
Although I had some time since with considerable labour brought together 
in manuscript all that has been published on the Irish Mollusca, and looked 
over all the collections possible, I have critically studied a small portion only 
of the subject. Without the aid therefore of my scientific friends, Mr. Alder 
of Newcastle-upon-Tyne and Professor Edward Forbes, the Mollusca as a - 
whole could not have been undertaken. In the Gasteropoda Nudibranchia 
and the marine Testaceous tribes their assistance has been most valuable. 
Some naturalists will consider the number of British species alluded to in 
the remarks on the different Orders much under what it should be. This 
arises from my adoption of the British list, as expurgated by the two distin- 
guished malacologists whose aid has been alluded to. A number of species 
which have from time to time been introduced without sufficient evidence are 
omitted; a number more are reduced to mere varieties ; and species figured 
or described in such a manner as not to be understood by the best informed 
on the subject, are unnoticed. 
In the Classes and Orders, Rang’s ‘ Manuel des Mollusques’ is chiefly fol-
