Chloritis molliseta, Pfr. 

 miix molliseta, Pfr. : Proc. Zool. Soc, 1862, p. 271. 



Pilsbry unites this species with C. circumdata, Fer. (Man. Conch., 

 vol. vi, p. 246). The two, however, appear to me to be distinct, for, 

 apart from its larger size, C. molliseta has a narrower \imbilicus, and 

 the aperture is relatively higher, the spire more deeply immersed, and 

 the hairs much more crowded. 



Chlokitis Ponsonbyi, n.sp. PL IV, Figs. l-lb. 



Shell discoid, thin, yellowish fulvous, with a few transverse, oblique 

 paler streaks, and a slight trace of a paler band above, near the suture, 

 paler below, finely striated, the penultimate whorl with a spiral row 

 of superficial but very distinct interrupted sulci nearest the inner 

 suture, and a few stray ones nearest the outer suture; the former 

 continue indistinctly up the first half of the last whorl. Spire plane, 

 suture impressed. Whorls 5, rounded, the earlier ones increasing 

 regularly and slowly, the last rather suddenly, and slightly dilated 

 towards the mouth, descending slightly and shortly in front. Aperture 

 subovate, oblique ; peristome whitish, thin, slightly reflected ; margins 

 approaching, regularly curved, coluraellar margin slightlj- overhanging 

 the moderate umbilicus, receding a little at first, then ascending 

 forward. Diam. maj. 22, min. 19 mm. ; alt. 10-5 mm. 



Hah. — Moluccas. 



Type in Mr. Ponsonby's collection. 



The present species is allied to C. imguicula, Fer., but is smaller, 

 thinner, and proportionately less high ; the whorls are more rounded, 

 the last descends less in front ; the aperture is wider and the peristome 

 thinner, and less reflexed. The exact habitat is not known, but, as in 

 the case of C. Eduardi, there can be little doubt that it belongs to the 

 Moluccas. 



Chloritis flexuosa, Pfr. 



Helix Jlexuosa, Pfr.: Proc. Zool. Soc, 1855, p. 112. 

 Helix Ceramensis, Pfr. : Proc. Zool. Soc, 1861, p. 192. 



While examining the type of C.flexuosa, Pfr., in the British Museum, 

 Mr. Smith called my attention to the resemblance of this shell to 

 C. Ceramensis, and, on closer inspection, it was found that both un- 

 doubtedly belong to one species, the former being somewhat abnormal 

 through having received some injury to the peristome while alive. 

 The name Jlexuosa (1855) antedating that of Ceramensis (1861), the 

 species must be known by the former name, the latter becoming 

 a synonym. 



Chloritis macrostoma, n.sp. PL V, Figs. 7-76. 

 Shell narrowly umbilicated, discoid, somewhat thin, irregularly 

 striated, dark chestnut colour, the penultimate whorl somewhat paler, 

 shining, and showing traces of very fine spiral sculpture under a 

 velvety deciduous cuticle. Spire subplane, suture shallow. Whorls 5, 

 increasing regularly, the last rather suddenly, subcompressed above 

 and below, slightly flattened and obtusely angulated near the suture,
