such Hemiplecta as Blainviileana, Humphrey siana 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. 
Pupina 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 constitute, et canali altero ad basin 
columella excisse, extus in foramen rotundatum terminato. 
Peristoma intus incrassatum, leviter patulum. 
Long. 7, diam. 3-|-; long, apert. 2| mill. 
Lnc. — Bismarck (or New Britain) Archipelago. 
This species is more slender than Pupina speculum, Tapparone- 
Canefri (Fauna Malac. Delia JSTuova 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 Pupina Beddomei. The same characters, 
although not very 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. E. Beddome.
