3. Helix (Geotrochus) woodlarkiana (Souverbie). 



Hub. Woodlark Island [Souverbie), Normanby Island, 

 D'Entrecasteaux Group (Brazier). 



The three specimens sent by Mr. Brazier from the above 

 locality differ in markings. All, however, are similar in 

 form, and agree in having the characteristic brownish or 

 violet stain at the upper part of the reflexed columella. One 

 specimen is waxy white, varied with opaque creamy white, 

 interrupted, obliquely arcuate streaks upon the upper part of 

 the body-whorl, and the spiral zones, as described in the type, 

 are only faintly noticeable. The peristome in this example is 

 of a brown flesh-tint, in the two other specimens it is white. 

 Souverbie's figure does not at all well show the pretty inter- 

 rupted bands which ornament the upper surface. The keeled 

 periphery appears to be constantly white. 



4. Helix [Geotrochus) Boyeri, Fischer & Bernardi. 



Hab. Admiralty Islands [F. & B.) ; Louisiade Archipelago 

 [Angus) ; east end of Woodlark Island (Brazier). 



Two specimens from Woodlark Island evidently belong 

 to this species, but are differently coloured from the type. 

 One is uniformly very light brown, with the exception of the 

 white lip and a small lilac stain in the umbilical region. 

 The other is cream-white, with two spiral brown bands, of 

 which one above the periphery is a little broader than the 

 other below it, and revolves up the spire. The slight pro- 

 minence on the inner columellar edge shown in the figure is 

 only present in one of the specimens at hand. 



5. Helix [Pajjui?ia) albocarinata. Smith. 



Hab. South Cape, British New Guinea ; also east end 

 of Woodlark Island [Brazier). 



The two specimens from Woodlark Island undoubtedly 

 belong to this species. They agree in every particular with 

 the type, excepting that one has a few narrow interrupted 

 opaque white zones on the upper as well as the lower surface, 

 whereas the other has none, being uniformly semipellucid, 

 with the exception of the opaque keel at the periphery. This 

 specimen also is a trifle less elevated than the type. All 

 have the yellowish stripe behind the slightly expanded lip. 



6. Helix [Hadra) bourkensis, sp. n. 



Testa anguste uinbilicata, depresse globosa, subtenuis, nitida, fla- 

 vescens, zonis duabus rufo-fuscis supra medium ornata ; anl'ractus
