Mr. R. B. Hinds's descriptions of new Shells. 83 



In size this shell approaches S. Lessoni, but is distinguished 

 from it by its coarsely striated surface, and by its different 

 markings. It is larger than S. castaneus, of a much darker 

 colour, more striated, and further distinguished by the two 

 dark yellowish bands on the upper part of the last whorl. 

 Some difference of opinion exists as to the propriety of con- 

 sidering some of these shells as distinct species, but I think 

 the specimens in my possession are sufficient to remove any 

 doubts on the subject. The locality of this species is the 

 most eastern of the genus ; and it may be as well to mention 

 that S. imbrium and S. castaneus are found in New Ireland, 

 and S. Lessoni in New Guinea. 



1. Pupina aurea. Testa ovali, nitida, aurea; suturis obsoletis; aper- 

 tura infra incisa, supra emarginata et dentata ; fissura sursum as- 

 cendente. PL VI. fig. 6. 



Hab. In the soil, New Guinea. 



This and the following species belong to the section of Pu- 

 pina, with two notches in the margin of the aperture. The 

 inferior one is in all cases a notch of more or less depth, but 

 the upper is not correctly either notch, fissure, or incision. On 

 the last whorl, near the outer lip, is a tooth, which together 

 form a channel or sinus, and here there is a slight degree of 

 emargination on the lip itself, so that at first appearance there 

 would seem to be much more of a notch than there really is. 

 This is a fine golden-coloured species; the notch is so deep as to 

 become a fissure, and takes an upward and backward direction. 



2. Pupina mitis. Testa ovali, parva, nitida, brunnea ; suturis obso- 

 letis linea rubra monstratis ; apertura infra incisa, supra emargi- 

 nata et dentata ; fissura recta. PI. VI. fig. 7. 



Hab. In dead wood, New Ireland. 



The appearance of my specimens is different as they are 

 living or dead shells ; the latter are as transparent as glass, 

 but the others are of a reddish brown or even of a grayish co- 

 lour. But after attentive examination I cannot doubt that 

 they are all one species. Nor is the reddish line which traces 

 the course of the sutures always very decided in the living 

 shells, and in the dead the colour of it has entirely disappeared. 

 The descriptive character of these two species is somewhat 

 similar, but when together they are very different. .This is 

 much smaller, wants the fine golden colour of P. aurea, and 

 has only a straight notch, for here it is no more. Mr. Cuming 

 has specimens of both from me. 

 Paludina seminalis*. Testa obtuse turrita, solidula, cornea, laevi ; 



* I have thought it expedient to publish descriptions of the above shells ; 

 but they are not to be regarded as a portion of the extensive collection of 

 Captain Belcher, C.B., about which I am now occupied.
