FULTOKT : LAND MOLLUSCA. FROM THE MALAY AECHIPELAGO. 217 



bulge or protuberance to the left of it ; aperture circular ; peristome 

 wbite, thin, broadly expanded, and continued over the parietal wall 

 of the last whorl. Diam. maj. 2-5, alt. 5 mm. 



Sah. — Macassar, Celebes. 



In addition to I). [Arinid) Ilinahassce, Kobelt,^ this and the next 

 are the only species of Biplommatina recorded from Celebes. The 

 nearest allied species is £>. {Palaind) chrysostoma, Smith, but 

 1). Moellendorffj is distinctly separated by its less oblong form and 

 its remarkable broadly expanded peristome. 



11.- DiPLOMMATiisrA (Palaina) tumens, n.sp. PI. XI, Fig, 4. 



Similar to D. Moellendorffi, but shorter, the penultimate whorl 

 smoother, compressed and bulging out beyond the body - whorl ; 

 peristome larger in proportion to size of shell than in B. Moellendorffi. 

 Diam. maj. 3'5, alt. 4-75 mm. 



Hah. — Macassar, Celebes. 



This curious form, of which only a single specimen was obtained, 

 may possibly prove to be but an abnormal form of D. Moellendorffi. 



12. DiPLOMMATiNA (Aeinia) Talautana, n.sp. PI. XI, Pig. 13. 



Shell dextral, oval, thin, rimate, semi-transparent, white shading 

 to golden above, closely and delicately costate ; Avhorls 5, rapidly 

 increasing, last three almost equal in width ; aperture circular, erect ; 

 peristome thin, continuous, with an outer flange or rim. Diam. 

 maj. 1'5, alt. 2*75 mm, 



^«5.— Talaut I. 



A very pretty and distinct species, readily distinguished from the 

 S. Flores species, I), hlanda, Smith, by its having a less number of 

 whorls and by its finer sculpture. 



13. DrPLOMMATiKA (Paxilltjs) l^vis, n.sp. PL XI, Fig. 14, 

 Shell dextral, oblong-conic, dirty white, smooth except for traces 

 of fine oblique striae on front of body-whorl, non-rimate ; whorls 7, 

 firs^t five almost flat, last two convex ; aperture almost vertical, 

 subauriform ; peristome double, inner portion slightly raised above 

 the outer rim, continued over the body-whorl by a thin transparent 

 callus; two folds on columella, lower one alone visible from the 

 exterior, upper one beginning about half a whorl from the exterior 

 margin of aperture, and continued interiorly ; on the interior side of 

 outer wall, and situated just above the peristome, are two short 

 transverse plaits, which can be seen from the exterior if the shell be 

 wetted, whilst on the parietal wall above there is a similar longi- 

 tudinal fold, which can only be seen by breaking the shell open; 

 above and to the left of the columella there is a remarkable tear- 

 shaped protuberance. Diam. maj. 2-25, alt. 4 mm, 

 Sah. — Pulo Laut, S.E. Borneo.
