452 LT.-COL. n. H. GODWIX-AUSTEJf OiS' THE LAND- [May 2l, 



columellar side of the aperture, which has almost a tooth on it. 

 NeA'ill records it from Koudul and Galathea Bay {Sioliczka). 



6. Ctclophoeus moeechianus, de Eoepstorff MS. (p. 444). 



Car Kicobar, June 1881. 



This shell was in Mr. de Eoepstorff's collection, with a label 

 written by Nevill, saying, " This is my no. 64, p. 275 of Hand- 

 list." I now consider it separable from C. charpentieri, and call 

 it C. moercliianus, de E. MS. No. 64 of the ' Hand-list ' is also 

 found on Batte Malve {F. StoliczTca). 



7. Ctclophoeus peedix, Broderip and Sowei-by (p. 444). 



No. 7. Ci/clophorus perdix, var. roepstor^ana, Nevill MS., Hand- 

 list. 



" Alt. 15"o, diam. 21*5 mm. Distinguished from C. zollinr/eri, 

 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 Eoepstorff)." 



To C. perdix Von Martens (Moll. Ost-Asien, p. 136) joins 

 C. zollingeri (Sunda Strait and Banka) and G. iwrphyretims, 

 Benson, from Penang. I find one J'omig shell of this species 

 among Mr. de EoepstorfPs shells, and I have three others, also 

 immatiu'e, sent to me by my brother from the Nicobars. 



Genus Leptopoma. 

 1. Leptopoma immactjlatiim:, Chemn. (p. 444). 



Nevill, in his MS. Hand-list, writes : " The L. vitreum. Lesson, 

 is scarcely separable from L. immaculatitm, especiall)' var. latilahre. 

 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 Eeeve." 



3. Leptopoma eoepstoeffianum (Nev.) (p. 444). 



This species is described in Nevill's ' Hand-Hst.' Vai". giganUa, 

 from the Andamans, and var. cdbida are given in his MS. copy. 



1, Lagocheiltjs wiJLLEESTOEFiAiS-us, PfeiflFer and Zelebor (p. 444). 



The operculum in this species is very thin, horny, shghtly 

 concave, and multispiral, flat in fi'out. 



In young specimens the surface is very rough, the spiral rib on 

 the periphery finely hirsute, and the fine transverse striation in 

 high rehef ; in this state the flame-like bands of colour are not 

 visible, they are only seen in the weathered shells. 



3. Lagocheilus eoepstoepfi, MiJrch (p. 444). 



Under this head Nevill, in his MS. Catalogue, gives -v'ar. 

 ivcoensis, from the Great Coco Island, collected by Ferd. Stoliczka.
