East end of Maud Island, opposite Leading Island ; one small speci- 

 men. A number of crushed, distorted and badly preserved examjdes 

 of a shell which agree in most particulars with the above quoted 

 description of T. cylindraceKs, tliough their columellar folds are veiy 

 indistinctly shewn, were collected by Mi'. James Richardson in 1872, at 

 Skidegate Channel, west of Alliford Bay, probably from exactly the 

 same locality as Dr. Dawson's specimen, which is certainly conspecific 

 with them. As indicated in the sj^nonymy, it is most likely that the 

 Actceonella oviformis of Gabb is identical with T. cylindraceus.
