Show 452 LT.-COL. H. H. GODWIN-AUSTEN ON THE LAND- [May 2l, columellar side of the aperture, which has almost a tooth Nevill records it from Koudul and Galathea Bay (Stoliczka). 6. CYCLOPHORUS MOERCHIANUS, de Roepstorff MS. (p. 444). Car Nicobar, June 1881. This shell was in Mr. de Roepstorffs collection, with a label written by Nevill, saying, " This is my no. 64, p. 275 of Handlist." I now consider it separable from C. charpentien, and call it C. moerchianus, de R. M S . No. 64 of the ' Hand-list' is also found on Batte Malve (F. Stoliczka). 7. CYCLOPHORUS PERDIX, Broderip and Sowerby (p. 444). No. 7. Cyclophorus perdix, var. roepstorffiana, Nevill MS., " Alt. 15*5, diam. 21*5 m m. Distinguished from C. zollingeri, Mousson, by the less dilated last whorl and smaller aperture, keel more developed, and coloration of base different. Great Nicobar (type var. coll. F. A. de Roepstorff)." To C. perdix Von Martens (Moll. Ost-Asien, p. 136) joins C. zollingeri (Sunda Strait and Banka) and C. porphyreticus, Benson, from Penang. I find one young shell of this species among Mr. de Roepstorff's shells, and I have three others, also immature, sent to me by my brother from the Nicobars. Genus LEPTOPOMA. 1. LEPTOPOMA IMMACULATUM, Chemn. (p. 444). Nevill, in his M S . Hand-list, writes : " The L. vitreum, Lesson, is scarcely separable from L. immaculatum, especially var. latilabre, Mart. (Ceram), of the former, which Pfeiffer indeed considered a form of the latter. Morch has correctly identified the type of Chemnitz's species as the Nicobar form. The Philippine form is certainly distinct; it must take the name of L. Iceve, as it is undoubtedly the form so-called by Wood and Reeve." 3. LEPTOPOMA ROEPSTORFFIANUM (Nev.) (p. 444). This species is described in Nevill's ' Hand-list.' Var. gigantea, from the Andamans, and var. albida are given in his M S. copy. 1. LAGOCHEILUS WULLERSTORFIANUS, Pfeiffer and Zelebor (p. 444). The operculum in this species is very thin, horny, slightly concave, and multispiral, flat in front. In young specimens the surface is very rough, the spiral rib on the periphery finely hirsute, and the fine transverse striation in high relief; in this state the flame-like bands of colour are not visible, they are only seen in the weathered shells. 3. LAGOCHEILUS ROEPSTORFFI, Morch (p. 444). Under this head Nevill, in his MS. Catalogue, gives var. cocoensis, from the Great Coco Island, collected by Ferd. Stoliczka. |
