NOTES. 



A New Irish Vertigo.— The occurrence of a living example of V't/- 

 tiyo heldi, Clessin, near Jialliutoy, Co. Antrim, is recorded by Mr. J3. Tomhn 

 (Iri.sh Nat., 1903, vol. xii, p. 110). Dr. Boettger, who has seen the specimen, 

 considers V. heldi as a sub-species of V. ulpestris. It differs, however, from 

 this latter species in the possession of an additional wliorl, and general larger 

 dimensions, it is reddish-brown in colour, has a feeble dentition, and a 

 differently shaped mouth.
