such Heniiplecta as Blainvilleaaa, Hitmjyhreysiana and Fouilloyi. 

 I received it under the latter name, but it is certainly utterly 

 distinct. The Fouilloyi is a large and more globose shell, more 

 narrowly umbilicated. In this respect the present shell is more 

 like Rhysota Achilles, Braz., but is smaller, has a thin aperture 

 and more numerous volutions. The sculpture may be the same 

 in both species. 



5. PupiNA Beddomei, n.sp. 



Fujnna Beddomei, Bttg., Cat. Staudinger. 



Testa ovata, tenuis, pellucida, hyalina, nitidissima, griseo- 

 albicans. Spira oblonga, obtusiuscula; anfractus 6 levissime 

 convexi, sutura callosa zona exili pellucida cincta divisi; ultimus 

 descendens, ad aperturam breviter ascendens, antice subdepressus. 

 Apertura basi antice provecta, rotundata, bicanaliculata, scilicet; 

 canali supero peristomate non extus exciso et lamina parietali 

 arcuata sat valida intrante constituto, et canali altero ad basin 

 columellfe excis?e, extus in foramen rotundatum terminato. 

 Peristoma intus incrassatum, leviter patulum. 



Long. 7, diam. 3|-; long, apert. 2| mill. 



Loc. — Bismarck (or New Britain) Archipelago. 



This species is more slender than Pupina speciUiun, Tapparone- 

 Canefri (Fauna Malac. Delia Nuova Guinea, 1883, p. 270, PI. x. 

 figs. 14-15), and indeed more nearly related to Pupina difficilis, 

 Semper, of the Pelew Islands. From the last named species it 

 differs in being a trifle larger, light ash-coloured, and chiefly in 

 the characters of the aperture, which is vertical in difficilis, also 

 furnished with a more robust superior lamina and more excised 

 columellar margin in Pupi7ia Beddomei. The same characters, 

 although not ver}^ striking, will also without much difficulty 

 distinguish Pupina Beddomei from the complanata, Pease, which 

 occurs in the Kingsmill and Caroline groups. They are very 

 constant in the several specimens before me. 



I am happy to give this species the name of my distinguished 

 correspondent Mr. C. F. Beddome.
