432 PLIOCENE MOLLUSCA. 



Stavanger to the Lofoten Islands, the Faroe Channel. Massachusetts, Gulf of 

 Maine. 



Fossil : Wexford gravels, Blackwater. 



Remarks. — While the present part of this Memoir is in the press, Mr. Bell 

 has received from Father Codd a parcel of shelly material from the Wexford 

 gravels, in which he has found a perfect though water-worn specimen of this 

 interesting shell. Rare as a recent form, it has only been recorded under the 

 above name as a fossil, so far as I know, from that locality. 1 T. vestita was 

 originally described by Jeffreys, as both generically and specifically new, from a 

 single example found on the east coast of Shetland. It has since been discovered, 

 during the expedition of the ' Lightning and Porcupine,' off the coasts of Norway 

 and from those of New England. It was at first referred to the Cancellariidae, but 

 is now more generally grouped with Trichotropis. It is unfortunately too late 

 to figure the Wexford fossil in the present issue, but I hope to do so in my 

 next Part. 



In his description of the type specimen of this species, Jeffreys remarks that 

 it is ornamented by five spiral and longitudinal stria?, but in his figures these are 

 shown to be of an inconspicuous character. The Wexford shell is without 

 sculpture but, as stated above, it appears to be water-worn.

1 In Jeffreys' opinion the Choristes elegans of Carpenter from the post-Tertiary of Montreal 

 approaches it, but Sir J. W. Dawson thought they were not the same.
