much excavated above by the penultimate whorl. Outer lip broadly 

 rounded, thin and sharp, inner lip spreading as a thin and broad callus 

 over the body -whorl, but forming a thick, white, and shining callus on 

 the concave columella. Basal lip narrowly rounded, not produced. 

 The columellar border is regularly S-shaped. Height 40, diam. 37 mm. 



llah. — This unique specimen was found by a fisherman near Cape 

 Farewell, and came into Captain J. Bollons' possession. He most 

 kindly presented it to me. 



Type in my collection. This shell shows a peculiarity which I do not 

 remember ever having seen in any other shell. Looking up from the 

 base, there is visible inside the columellar border a perforation right up 

 to the apex of the shell, having a diameter of about 3 mm. at the base ; 

 the columella does not form a vertical solid pillar, but is wound up in 

 a spiral, leaving a free space in the centre. I use the generic name 

 Euspira, Desor & Agassiz, 1837, as jiroposed by Harris in his 

 Cat. Tert. Moll. Brit. Mus., pt. i, p 264. 



This species is very nearly allied to the Pliocene shell Sigaretus (?) 

 Brewi, Murdoch,^ and has almost the same size, but is distinguished 

 from it by being more globose, the periphery not flattened, the 

 columella more concave, and the presence of two umbilical ridges. 



The Rev. Mr. Webster first announced the occurrence of the genus 

 as recent in New Zealand waters by enumerating amongst shells to be 

 added to the fauna list Sigaretus undulatus, Hutton, from Cape Maria 

 van Diemen^ I have not seen his specimen, bat it seems to be very 

 different from the species now described. It is a highly interesting 

 fact that New Zealand has two species still living, while the only 

 other known recent species, £. fluctuata. Sow., inhabits the Philippines. 



As my specimen is an empty shell, we remain for the present in 

 ignorance with regard to operculum and animal.
