V. — Desertions of some new Shells from Kergueleri 's Island. 

 By Edgar A. Smith, F.Z.S., Zoological Department, 

 British Museum. 



The following species form part of the collections made at 

 Kerguelen's Island by the Rev. A. E. Eaton, the naturalist 

 sent by the Royal Society with the British expedition for 

 observing the recent transit of Venus. Only those species 

 are here mentioned which are apparently undescribed, as it is 

 purposed to publish elsewhere complete and detailed accounts 

 of all the specimens obtained at the island. Of Mollusca the 

 number is small, comprising only about twenty species ; but 

 of these the proportion of new forms is large, and several of 

 them very remarkable discoveries. 



1. Struthiolaria mirabilis, sp. nov. 



Testa ovata, tenuis, imperforata, leviter turrita, alba, epidermide 

 tenuissima fugaci olivaceo-alba arnicta ; anfractus G|, convcxius- 

 culi, superne anguste planulati, lente accrescentes, longitudinaliter 

 oblique arcuatimque crebre plicati (plicis inferne ad suturam vix 

 attingentibus) ; liris spiralibus prorainentibus supra plicas undu- 

 latis (in anfr. superioribus 7-8, in xiltimo circiter 22, illis infra 

 medium simplicibus) succinct! ; apertura longitudinis totius circiter 

 A aBquans ; columella arcuata. 



Operculum corneum unguiculatum, inferne costis duabus a nucleo 

 unguiformi divergentibus munitum, superne medio longitudinaliter 

 unisulcatum, concentrice striatum. 



Long. 42 mill., diam. 22. 



Ilab. Swain's Bay, Kerguelen's Island. 



But a single specimen of this very remarkable shell was 

 obtained by Mr. Eaton. This unfortunately has the labrum 

 so much broken away, that it is impossible to describe the 

 form of the aperture and the nature of the basal channel. 

 However, the animal and operculum agree in all respects ex-
