ON THE FAUNA OF IRELAND. 247 
stead, to leave this to be indicated by the tabular mark of distribution, al- 
though it may often prove unsatisfactory. Thus, species which have been 
found but once on each side of the island are marked as conspicuously under 
north, east, west and south, as those which are abundant round the coast. 
But naturalists will not be deceived by this; none will imagine that because 
Eulima subulata exhibits the same number of asterisks as Rissoa ulve, that 
the species are equally plentiful; but all will know that the former, though 
widely distributed, is found in extremely limited numbers, and the latter in 
abundance where they respectively occur. Nor, was it deemed necessary in 
so brief a summary, to give the authorities for the occurrence of the various 
species ; but reference is made throughout to the works in which all the details 
published respecting them will be found. 
MOLLUSCA. 
Catalogues of the testaceous Mollusca of Ireland, elaborated during the 
residence of their respective authors in this country, were drawn up about the 
same time by Capt. Brown and Dr. Turton*, in which they were aided by the 
collections of Mr. O’Kelly of Dublin, Dr. Thomas Taylor eal contributed 
by Miss Hutchins of Bantry), Mr. Samuel Wright of Cork, Mrs. Clewlow, Dr. 
M°Gee, Dr. M*Donnell, and Mr. Templeton of Belfast+. Mr. Templeton, 
before and after the period of their researches, was silently noting down for 
future publication all that he could learn upon the subject, but, stationary 
at his country residence, he was less favourably circumstanced than either of 
those gentlemen, by whom various parts of the country and coast were 
visited. Their inquiries, directed to a single branch of natural history, 
were naturally more productive in that one department than his, whose sur- 
vey embraced the whole Flora and Fauna of Ireland, for the illustration of 
which he was diligently collecting materials. To Bryce’s ‘Tables of Simple 
Minerals, Rocks and Shells,’ found in three of the northern counties, Mr. 
Hyndman contributed a few hitherto unnoticed species. The native Mol- 
lusea, more especially of Youghal and Dublin, have been effectively collected 
and studied by Mr. Robert Ball, aided by his sister Miss M. Ball; as have 
those of Limerick and Miltown Malbay, on the western coast, by Mr. Wm. 
Henry Harvey; those of Cork by Mr. John Humphreys, and those of the 
northern shores by Mr. Geo. C. Hyndman. A few species of the highest 
interest from the northern province have been obtained by Dr. J.L. Drummond, 
as have some from the southern by Dr. Geo. J. Allman. The extensive and 
beautiful collections of Mr. T. W. Warren and Dr. Farran of Dublin, more 
particularly of species from the neighbouring coast—the richest in Ireland— 
have rendered most important aid towards an elucidation of the subject. 
The Ordnance collection has contributed in so far as the comparatively poor 
coast investigated could afford. Mrs. Hancock has rendered essential service 
by assiduously collecting the species of the western shores, at Ballysodare 
in the county of Sligo, and Bundoran in the county of Donegal, and trans- 
mitting them to Belfast, where they came under the inspection of Mr. Hynd- 
man and myself. — 
* Capt. Brown’s memoir was dated from Naas Barracks, Ireland, Aug. 20, 1815, 
and read before the Wernerian Society of Edinburgh on the 16th of December in that 
year (see Wern. Mem. vol. ii.). Dr. Turton’s appeared in the ‘Dublin Examiner, 
or Monthly Miscellany of Literature, Science and Art,’ in July 1816. In the 
subsequent works of these authors additional Irish species were described: all in the 
following catalogue that are noticed by them only (i. e. unknown to my correspondents 
and myself) are marked as on their authority. 
+ Ata subsequent period, the collection of James Rose Clealand, Esq. of Bangor in 
the county of Down, contributed some interesting species to Sowerby, &c.
