Type material.

China, coll. Swinhoe, NHMUK 1870.7.16.6 (3 shells, probably syntypes, Fig. 13A ) • Chine, Ichang & Fungsiang, Achat Sallé, MNHN-IM-2014-7932/3 (probably syntypes).

Museum material.

Asia Centrale , MNHN-IM-2014-7933/3 • Asia Centrale, MNHN-IM-2014-7934/7 • Hupé, China, coll. Staadt, 1969, MNHN-IM-2014-7929/2 + 1 L. carinifera shell (mixed sample, erroneous locality for L. carinifera ) • Moupin, leg. Abbé David, coll. Deshayes, 1872, MNHN-IM-2014-7945/2 (probably erroneous locality) .

New material.

China • 10 shells; Hubei, Enshi Tujiazu Miaozu Zizhizhou, Badong Xian, east of Badong , Bashan Senlin Gongyuan , (next to Xinlingzhen) (locality code: 2010/29); 31°01.472'N, 110°25.284'E; 225 m a.s.l.; 03 November 2010; A. Hunyadi leg.; HA (Fig. 13B ) .

Distribution.

The type localities and the newly collected sample suggest that this species lives more upstream in the Yangtze valley than L. filippina . The samples from Moupin (Baoxing County, Sichuan) are probably erroneous. We indicated only the newly collected sample on the map (Fig. 14 ).

Remarks.

We found three samples in the NHM. One of them, containing two shells, was labelled Helix christinae . The other two lots, labelled " Helix christinae var.", contained three shells each. The latter two samples are probably syntypes of Helix christinae var. carinifera , described in the same publication ( Adams 1870; see further details under that species). None of the two Helix christinae shells (NHMUK 1870.7.16.6) are identical with the shells figured in the original description ( Adams 1870: pl. 27, figs 4, 4a). However, the indication of the collector (Swinhoe) agrees with the collector mentioned in the original description. Thus, we treat the two shells of that lot as syntypes.

Adams (1870) gave two type localities: "Ichang and Fungsiang gorges, China". The former is situated upstream of Yichang City in Hubei (30°56'N, 110°48.7'E), whereas the latter is Fengxiangxia, Fengjie County in Chongqing (31°2'N, 109°35'E). Our sample 2010/29 is geographically located between the two type localities. The shells of this sample are identical with the types, but they are smaller.
