MOLLUSCA. 
this mollusc may lead to some interesting geological inferences, and should give 
a stimulus to the students of Irish Natural History, to endeavour to add by 
unremitting attention and examination to the Fauna of their country.” — Saunders' 
News-letter , Oct. or Nov. 1850. 
Prof. Forbes writes me that he saw this shell, which is P. papyracea. 
He went to the locality, and convinced himself that it had been found 
there. 
P. striata, Linn. 
January 7, 1842, I was favoured with the following communication by 
Mr. Warren of Dublin: — “ I send for your examination a Pholas which is 
new to me, and should like to know if it has been obtained before in Ire- 
land. It was found with others in a piece of water-logged mahogany, 
near Killala, in the County Sligo, by Richard Glennon, jun.” With the 
letter were a single valve and a perfect specimen, which corresponded 
well with the descriptions of Montagu and Fleming ; the specimens were 
4 lines in length, and 7^ in breadth; the plate at the hinge “sub-oval,” 
as described by Montagu. 
In January , 1844, I was further informed by Mr. Warren, that he had 
received a specimen of this Pholas from Mr. Gaggot, who found several 
on the coast of Clare. The occurrence of the species in the first instance 
was, I believe, noticed in the Dublin Penny Magazine. 
P. dactylus, Linn. 
Howth (Mr. O’Kelly), Brown. Burrowing in variegated marl, from 
midway between high and low water mark to the latter, near Carrick- 
fergus Castle, and other parts of Belfast Bay. Youghal, Dr. Ball. Bally- 
cotten, Miss Ball. 
P. parva, Mont., 
Was procured some years ago off the Long Strand, Belfast Bay, by Dr. 
J. L. Drummond ; subsequently by the Ordnance collectors at Whitehouse 
Point, in the same Bay. 
P. candidus, Linn. 
Dublin Bay, rare, Br. With P. dactylus in the locality named, W. T. 
More common than it in Belfast Bay, and much more so than P. crispata. 
P. Candida is the only Pholas included in the lists of western Mollusca 
supplied me, and only as found at Birterbuy Bay, by Dr. Farran, who 
states that it is common there. Youghal, Dr. Ball. 
Genus Teredo. 
T. bipennata, Turt. 
From the mast of a vessel cast ashore at Youghal, Dr. Ball. Miltown 
Malbay, Prof. W. H. Harvey. 
T. Norvagica, Spengler. 
Previously included in Bryce's Tables, &c., but probably from sub-fossil 
specimens. 
Mr. Getty sent me specimens found in blue clay near Belfast, Oct. 11, 
1844. 1847, Kingstown, Dublin Bay, Dr. Ball. 
Donaghadee (Co. Down), the animal alive. 
Miltown Malbay (Co. Clare), in drift timber.
