358 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 Faima of their country." — Saunders' 

 News-letter, Oct. or A'ov. 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 Pliolas 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." AYith 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.

 supplied me, and only as found at Birterbuy Bay, by Dr. Farran, who 

 states that it is common there. Youghal, Dr. Ball.
