108 PROCEEBINGS OF THE MAXACOLOGICAL SOCIETY. 



to be an even closer ally. Hcude says, however, in his description : 

 " anfr. vix convexi, sutiira vix improssa;" — besides, it has only four 

 genuine plica) palatales, whilst the lamella superior is much more 

 oblique. C. commimita, Heude, is more slender in form, 16 mm. lone^ ; 

 the figure shows four genuine plica) palatales, the upper and the 

 lowermost of which are longer than the intermediate ones, so that 

 there is no doubt that the species is distinct from ours. We have not 

 had the opportunity of comparing the original specimens of the two 

 last-named species. 



A single specimen from Kiatingfu differs in some respects ; pro- 

 ■v^sionally we will call it var. discreta, n. var. It may be characterized 

 by the following diagnosis, viz. : 



Testa niajore, graciliore, pallidiore, spira magis exserta lateribus 

 fere convcxiusculis, apice acutiore, anfr. 10, apertura magis oblic^ua, 

 peristomate magis infundibuliformi-expanso, lamella inferiore paullulo 

 minus recedente. Alt. 14-25 mm. ; diam. max. 3 mm. 



13. Clatjsilia psetjdobensoni, n.sp. 



Bocttger, in Hilber, Sitz. Ber. Akad. Wien, Abth. I. 1883, p. 1375, 

 t. vi. fig. 8 ( C. Bensoni, non H. Ad.). 



Testa profunde rimata, periomphalo sat magno, fusiformi-clavata, 

 solidiuscula, sericina, obscure castanea vel purpureo-cerasina, sutura 

 et basi pallidioribus, soepe albido late marginatis ; spira turrita 

 lateribus convexiusculis ; apex pallidior, acutus. Anfi\actus 9-10 

 convexi, sutura profunda, fere subpapillifera disjuncti, dense 

 capillaceo-striati, striis rugulosis hie illic inter se confluentibus, 

 ultimus penultimo parum angustior, basi rotundatus et subsaccatus, 

 ante apert. leviter ascendens, non validius striatus quam penultimus, 

 fere i altitudinus testae gequans. Apertura subverticalis, circulari- 

 piriformis, faucibus fuscis ; peristoma continuum, breviter solutum, 

 modice expansum et reflexum, albo sublabiatum ; lamellae humiles, 

 superior marginalis, a spirali profunda, vix conspicua longe separata, 

 inferior oblique ascendens, recedens, intus subfurcata ; subcolumellaris 

 inconspicua. Plica principalis brevis, suturae approximata, loco 

 lunellee arcus obliquus plicularum palatalium 7-12 superne et inferne 

 longiorum inter se magis distantium, media parte breviorura valde 

 approximatarum. Lamella inferior et spiralis intus altior in faucibus 

 longitudine ajquales. Clausilium modice latum, basi oblique 

 truncatum, apice acuminato-rotundato. 



Hab. — Kwang-juen-hsien (Quang-juon), province Sytshouan ; on 

 rocks, frequent ; cf. Hilber, I.e. 



Mr. Schmacker's collector brought this species from Iviatingfu, 

 province Sytshouan. The specimens measure alt. 12-5-17-5 mm.; 

 diam. max. 3-4 mm. ; alt. apert. 3-5-4-25, lat. apert. 2-75-3-25 mm. 



Mr. Bock's collector found it at Denya (ubi?), where it does 

 not appear to attain the same size, the specimens measuring from 

 12-3 to 15-3 mm. 



As for its relationship to other species, especially C. Milberi, Bttg., 

 cf. I.e. p. 1376. C. palUdocincta, i\Iolldff., is smaller, the sculpture is 

 finer, the lamella superior is rudimentary, the lamella inferior placed 

 horizontally and spirally twisted inside.
