BOETTGEE AKD SCHMACKEE : CHOfESE CLATTSILI^. 107 



A comparison of our specimens with the type of C. Bensoni in the 

 British Museum (]!^atural History) has proved beyond doubt that we 

 have before us the species described by H. Adams. What Boettger 

 took for C. Bensoni has turned out to be a new species — C. pseiido- 

 bensoni — the diagnosis of which will be foimd in this paper. Adams' 

 diagnosis may with advantage be supplemented by the following 

 additions, viz. : 



Testa subclavato-fusiformis, anfractibus 10-1 H, capillaceo-striata, 

 striis hie illic leviter undulatis et quasi mallcolatis, in cervice 

 validioribus. Apertura faucibus fuscis, lamella superior obliqua cum 

 spirali continua, subcolumellaris inconspicua, plica principalis longa, 

 liueam lateralem attingens, palatales dorso-laterales 4-6 sat longge, 

 lougitudine deorsum decrescentes. Palatales antrorsum cum principali 

 divergentes. Clausilium uti in C pseudohensoni. 



Hub. — Chunking, province Sytshouan (Schmacker's collector). 

 Alt. 15*2-18 mm.; diam. max. 3-8-4 mm. We have besides one 

 specimen from Lytshouanhien, collected by Father L. Fuchs, received 

 through Dr. Henry. Alt. 15'7mm. ; diam. max. 3'5 mm. Lytshouan- 

 hien is probably somewhere in the province of Hupeh.

Aff. C. pseudobensoni, Schmacker and Boettger, sed minor, nitida, 

 fere Isevis, lamella inferiore multo magis recedente, fronte inspicienti 

 aut vix aut non conspicua. Testa parva, subrimata, fusiformis, 

 solida, rufocastanea, ad suturas pallidior; spira turrita lateribus 

 convexiusculis ; apex modice acutus. Anfr. 8-9 convexi, sutura 

 profunde impressa disjuncti, obsolete striati, ultimus deorsum leviter 

 angustatus, latere planatus, basi rotundatus, ante aperturam leviter 

 ascendens, regulariter costulato-striatus et striis spiralibus obsole- 

 tissimis reticulatus, f altitudinis testse tequans. Apertura parum 

 obliqua, axialis, angulato-piriformis, faucibus fuscis ; peristoma con- 

 tinuum, solutum, expansum, reflexiusculum, brunnescenti-labiatum. 

 Lamella superior marginalis parum obliqua, e basi parum compressa 

 triangulari oriens, humilis, cum spirali continua ; inferior perprofunda, 

 recedens, fronte intuenti vix conspicua, profunde in faucibus bipartita; 

 subcolumellaris inconspicua. Plica principalis longissima, intus lineam 

 lateralem transgrediens, antice fere usque ad peristoma accedens, loco 

 lunellae plicae palatales laterales 5-6 longse, longitudine deorsum 

 decrescentes. 



Hab. — Kiatingfu, province Sytshouan: alt. 10'8-12-5 mm.; 

 diam. max. 2-6-3"3 mm. ; alt. apert. 2-5-3, lat. apert. 2-2-8 mm. 

 Lochaba (province Hupeh ?) : alt. 11-5 mm.; diam. max. 2-8 mm.; 

 alt. apert. 2-6, lat. apert. 2-2 mm. (Schmacker's collector). The 

 species was also collected by Mr. Bock's men, but no locality was 

 given. The dimensions do not differ from those given above. 



The plicae palatales are relatively somewhat larger than in C. 

 pseudobensoni, Schm. and Bttg., besides which the neck does not bulge 

 out so much, and the striation is very much finer. The light zone 

 under the suture, and the form of the aperture in the last-named, 

 show it to be nearly related to this species as well as to C. Bensoni,
