" Trochact. testa ovato-elongato, cylindracea, antice et postice paulo 

 attenuata, spira plus minusve prominente, obtusiuscula ; anfractibus 

 angustis, postice oblique et anguste applanatis, deinde subcarinatis ; 

 striis incrementi in superficie ultimi anfractus lente curvatis, apertura 

 longa, postice angustissima, antice latiore ac rotundata ; labro ad 

 marginera acutiusculo, levigato, antice oblique late ac lentissim e effuso ; 

 labio levissimo, postice paulo incrassato, antice triplicate : plica antica 

 tenuissima, postice crassissima." Stoliczka. 



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

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

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

 description of T. cylindraceus, though their columellar folds are very 

 indistinctly shewn, were collected by Mr. James Eichardson 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 synonymy, it is most likely that the 

 Actceonella oviformis of Gabb is identical with T. cylindraceus.

Burrows of a species of Teredo which cannot at present be distin-
