9. Hemiplecta Bonthainensis. pi. YII, Fig. 20. 



Testa depresse conoidea, ad peripheriam obtuse carinata, perforata, 

 tenuis, saturate vel dilute purpureo-fusca, circa umbilicum virescens, 

 ad angulum medianum plerumque flavescens ; spira breviter conica, 

 ad apicem mediocriter acuta, baud nitida ; anfractus 5-6, leviter 

 convexiusculi, lineis iucremcnti obliquis arcuatis aliisque spiralibus 

 numerosis granulatim decussati, ultimus infra angulum convexior, 

 nitens, lineis concentricis versus umbilicum sensim evanidis ; apertui-a 

 obliqua, late lunata, intus concolor; peristoma tenue, simplex, iu 

 exemplis adultis ad marginem levissime incrassatum et luteum, 

 marginibus distantibus, columellari ad insertionem breviter expanse 

 et reflexo. Var. Testa omnino dilute flavo-virescens. Diam. maj. 34, 

 min. 28, alt. 22 mm. 



Hab. — Bontbain Peak, South Celebes, at 4,000 feet. 

 Considerable variation in form and colour is observable in the series 

 of specimens examined, but the sculpture is similar in all. Some 

 examples are of a very dark purplish-brown or black colour 



! throughout, with the exception of the umbilical region. Others 

 are of a lighter tint. Some are greenish, with a broad purple- 

 brown zone beneath the periphery, whilst others are uniformly light 



j yellowish- green. The spire is more elevated and the body-whorl 



! more inflated in some specimens than in others. 



10. Rhtsota eugata (Martens). 



Nanina rugata, Martens, Preuss. Expcd. Ost-Asien, Zool. vol. ii, 

 j p. 229, pi. X, fig. 5. 



' JTffi.— South Celebes, at 2,000 feet. 



This species has already been quoted from the southern part of the 

 j island by Wallace and by Martens. Young shells are very sharply 

 I keeled and angulate, and the two apical whorls are peculiarly 

 j malleated, a feature also observable in more adult specimens. 



11. Obba marginata (Miiller). 



j Yar. sororcida, Martens, Preuss. Exped. Ost-Asien, Zool. ii, p. 294, 

 pi. xvii, fig. 4. 



I ^«J.— South Celebes, at 2,000 feet. 



I It is interesting to find this species occurring in the south of the 

 J island as well as the north. Similar small examples also occur at 

 the Philippine Islands. 



12. Chloritis PLENA (Godwiu-Austen). 



Helix {CJdoritis) plena, Godwin-Austen, Proc. Zool. Soc. 1891, p. 44, 

 pi. ii, fig. 8. 



mi).— ^ouih Celebes, 2,000 feet (Everett) ; Labuan (G.-A.). 

 Yar. Celehensis, n. 



Only a single specimen was obtained by Mr. Everett. It is rather 

 smaller than the type from Labuan (maj. diam. 16 mm.), consisting 

 of half a whorl less, the peristome is faintly tinted with livid lilac,
