SMITH : LAND SHELLS FROM NEW GUINEA. 21 



The specimens vary in size, some being more slender than 

 others, and intermediate degrees of costation are also occasion- 

 ally met with. When the genus is re-monographed, it is 

 probable that some older name will be discovered to replace 

 that of valida. 



g. Pupinella strubelli, n. sp. (PI. II., Fig. 13). 



Testa imperforata, oblongo-ovata, superne acuminata, dilate 

 fusco-cornea, baud nitida, lineis incrementi tenuibus obliquis 

 striata ; anfractus 6, superiores quinque convexi, ultimus minus 

 convexus, obliquus, antice paulo descendens, supra aperturam 

 leviter planatus, ad basin pone fissuram columellarem cristatus ; 

 apertura subcircularis, pallide flavescens vel sordide albida ; 

 peristoma expansum, reflexum, incrassatum, dilute flavescens 

 fissura columellaris parva, angusta ; labrum ad insertionem 

 leviter canaliculatum. 



Longit. II millim., diam. 6 ; apertura intus 3. 



Hab. : Djamna Island, Dutch New Guinea, off north coast. 



A specimen of this species has been presented to the British 

 Museum by Herr Bruno Strubell, after whom I have named it. 

 P. fultoni, Smith, 1895 (— P- ^''i^ola, Brancsik''-), is a closely- 

 allied form, but a little larger, having a deeper columellar slit, 

 but lacking the basal crest which occurs in the present species. 

 C. strnhdli, through the obliquity of the body-whori, has a some- 

 what distorted look, like certain forms of Stvcptaxis. The 

 columellar callus extends in a curve towards the termination 

 of the outer lip, with which it forms a slight canaliculation. 

 Herr Strubell informs me that Djamna or Djammna Island is 

 situated off the north coast of the island. 



10. Helicina pachystoma, n. sp. (PI. II., Fig. 14). 



Testa turbinata, solida, flava ; spira conica, ad apicem 

 subacuta ; anfractus 5 leviter convexiusculi, oblique tenuiter 

 striatuli, ultimus postice rotunde subangulatus, antice infra 

 angulum descendens ; apertura intus flavescens ; peristoma 

 expansum, valde incrassatum, albo-pellucidum ; callus basalis 

 mediocris, flavescens, circumscriptus. 



Diam. maj. 8 millim., min. 6i-, alt. 7. 



Hab. : Neu Pommern ( = New Britain).
