the island of Mindanao, Philippines. The basal aspect of 

 that species {vide ' Voj. Samarang,' Mollusca, pi. xvi. fig. 9, 

 or Reeve, 'Conch. Icon.' fig. 528), both as regards size and 

 banding, is very similar to that of H. lacteolota. The latter, 

 however, has a ver j much more elevated spire, a more raised 

 bodj-whorl, and the volutions increase less rapidly. The 

 coloured bands are eight in number on the last whorl ; most 

 of them are almost black and generally margined with brown 

 and more or less blotched and smeared with an opaque cream- 

 colour. 



Helix {Papuina) roseolabiata. (PI. XV. fig. 2.) 



Testa imperforata, conica, trochiformis, alba, ad apicem nigrescens, 

 ad peripheriam et circa suturam zona nigro-fusca cincta ; anfrac- 

 tus 5, primi duo convexi, cteteri convexiusculi, oblique rugose 

 Btriati, ultimus acutissime carinatus, supra carinam paulo con- 

 cavus, iuferne planiusculus, similiter sculptus, antice prope 

 labium breviter descendens, ad aperturam contractus, intus lila- 

 ceus ; apertura oblique producta, rostrata, irregulariter triangu- 

 laris, intus alba, infra suturam quoque ad carinam uigro-fusco 

 aonata ; peristoma rosaceum, margiue dextro in medio procurvo, 

 breviter expanso, inferiore latins dilatato, columellari reflexo, 

 appresso.

This species has even a more rostrate aperture than H. 

 Tayloriana, and is well characterized by its rosy lip, the acute 

 keel around the periphery, and the marked contrast of the 

 brown band upon the white ground.

This I believe to be a species which varies considerably 

 both in form and colour, but not much in sculpture. The 

 type, which is in the British Museum, is well figured (as 

 regards shape) by lieeve *. The keel is, however, in some 

 specimens even more acute, and the spire is concave instead 

 of slightly convex. On the other hand, other examples are 

 less acutely keeled, and the aperture is not so much produced 

 or beaked. These constitute the H. yulensis of Brazier f, 

 which in other respects, excepting small differences in the 

 colour-markings, agrees with the typical form. A third 

 variety (PI. XV. fig. 1 a) has just been sent to the Museum
