BOETTGER AND SCHMACKER : CHINESE CEATTSILIiE. Ill 



been published when we wrote our description of C. alhopajnllata. 

 Gredler fell into the same trap (of. Nachr. El. d. d. Mai. Ges. 1890, 

 p. 39). An original specimen from Heude of alt. 22, diam. max. 

 4 mm., establishes beyond a doubt the identity of the two species. 



18. Clatjsilia LONGisPiNA, Heudc. 

 Heude, Moll. terr. p. 121, t. xxxi. fig. 12. 



This species closely resembles C. lejJtdospira ; the " papillae " below 

 the suture of the latter are, however, absent in C. longispina (cf . Nachr. 

 El. d. d. Mai. Ges. 1890, pp. 21, 39). We have before us original 

 specimens from Heude, measuring alt. 20'5-24-5 mm. ; diam. max. 

 3-8-4 mm. 



19. Clatjsilia Seguikiana, Heude. 

 Heude, Moll. terr. p. 120, t. xxxi. fig. 8. 



Doubtless belonging to subsect. Formosana, as proved by an original 

 specimen in our possession. Its place in the series is probably next to 

 C. Magnaciana, Heude. Our specimen is not in good condition, so 

 we cannot say more. 



IV. Sub-sect. Bextroformosana, nov. 



Testa dextrorsa, multispira, subclaviformis, in cervice non aut vix 

 validius striata quam in anfractibus cjeteris ; lamella superior marginalis, 

 inferior oblique ascendens, subcolumellaris aut emersa aut subimmersa. 

 Plica principalis distincta ; loco lunellae 4-5 plicae palatales aut longas, 

 aut modicae. — Sinae prov. Hunan, Hupeh et Kiang-shi. — Typ. : Clausilia 

 Bemprinii, Gredl. 



In this section, which differs from the section Formosana, Ettg., 

 principally in the fact that the shell is invariably dextral, we place 

 C. Semprinii, Gredl. ; C. antilopina, Heude ; C. Kiartgshiensis, Gredl. ; 

 C. moschina, Gredl. Specimens of all of these, received from the 

 authors, are now before us : with them we also place C. psilodo7ita, 

 Heude, the type of which we have not seen. 



20. Clausilia antilopina, Heude, var. unicornu, n. 

 = antilopina, Gredler typ., non Heude. 



Differt a typo testa majore, magis clavata, castaneo-fusca, magis 

 nitida, anfr. 1 1-13 nee 10-1 1 convexioribus, penultimo et ultimo subtus 

 minus angustatis, cervice non distinctius striato quam anfr. penultimus. 

 Apertura major duplo minus protracta, ovato-piriformis nee circulari- 

 piriformis, superne magis acutata, sinulo latiore, lamellis debilioribus, 

 subcolumellari magis immersa, peiistomate minus expanso, angustius 

 albolimbato. Caeterum typo simillima. 



We have this shell from Changya (Mr. Eock's collectors in 1891 ; 

 it is rather doubtful whether the locality is the Changyang of the 

 expedition of the year before, as the shell was not then found by 

 them), measuring alt. 19-27 mm. ; diam. max. 4*3-5 mm. ; also from 

 Patung, province Hupeh, measuring alt. 18"5-24*3 mm. ; diam. max. 

 4-3-4 6 mm. 



The most notable differences in this variety from the type are 



the form of the shell, which is more club-shaped, and the larger, more 



oval aperture, which has a narrower peristome. However, these 



differences are so slight, and so subject to variation, that we have not
