116 PKOCEEDINGS OF THK DJALACOLOCilCAL SOCIETY. 



Schmacker and Boettger, Nachr. Bl. d. d. Mul. Ges. 1890, p. 20 

 (C. CeciUei). 



There is no doubt now that the species Boettger described as 

 C. clarocincta and the species from Dongao, a ravine west of Ningpo 

 and south of the Snowy valley, are C. Fortunei, Pf. Comparisons 

 instituted in the Berlin Museum, with a specimen in Albers' collection, 

 and in the British Museum (Natural History) with the type in Cuming's 

 collection (Pfcilfcr's handwriting), have established this fact beyond 

 a doubt. The identity of Ileude's C. Fortunei remains, however, 

 still uncertain. He has himself finally expressed doubts about his 

 identification, and has changed the name of the species described 

 and figured to C. veruta {I.e. p. 162). Now Schraacker has had in his 

 collection for some years a specimen, received from Heude as C. 

 Fortunei, from Tche-tcheoufu, which has a distinct lunella, and which 

 we find it impossible to separate from C. CeciUei. Later on the 

 learned Father gave him a specimen from Isingkuofu, which 

 corresponds with his figure and description in having a number of 

 distinct plicae palatales, and finally he has in his collection, also 

 obtained from Heude, two specimens of C. veruta vars. major and 

 minor. Var. major has a luncUa and again appears to be C. CeciUei, 

 whilst var. minor is probably a distinct species. The colour is a light 

 horn-yellow, the aperture is smaller, more rhombic, lamella superior 

 and lamella inferior are closer together, and seen from below are 

 distinctly angulate. The lunella is dorsal, the plica principalis very 

 short — only 3-5 mm. long. The peristome is adnate above. 



We may have more to say on this subject later. 



We have to correct our statement (Nachr. Bl. 1890) that C. Fortunei 

 has no lunella. Of eleven specimens broken up three had a callous 

 ridge ; the others had only indications of one. 



C. Fortunei and C. CeciUei being so very much alike, we consider it 

 useful here to give their principal differences in detail.
