Rhachistia sticta (Mts.), 1860. 



1860. Bulimus (Rhachis) stictus Mts., Mai. Blatt. vi, p. 211, pi. 2, 

 fig. 6. D.F. 



Hab. L. Marques. Tette (Peters) ; Manica Land (Selous) ; Gorongozo 

 District (Wells Cole) ; Mtisherra R. Valley ; Dondo District ; Zangwe 

 Basin (Cressy). 



This species attains much greater dimensions than have hitherto been 

 attributed to it, the largest specimen known to me measuring 26-3 X 13-0 mm. 

 The beautiful pink and yellow markings soon fade away in weathered 

 shells, but the black spots usually remain as a fairly safe guide to correct 

 identification. 



Family PUPILLIDAE. 



The arrangement of the genera here adopted is in accordance with 

 recent volumes of Pilsbrv's Manual. 



Subfamily PUPILLINAE. 



Genus Pupoides Pfr., 1854. 



{= Leucochiloides Pfr., 1881.) 



Pupoides coenopictics (Hutton), 1834. 



1834. Picpa coenopicta Hutt., J.A.S. Bengal, iii, pp. 85, 93. D. 



1912. Leucochiloides soror Preston, P.Z.S., p. 188, pi. 31, fig. 17. D.F. 



Hab. Mozambique (Layard). 



L. Marques. Wanetsi R., Magude District (Bell Marley). 



The specimens from both the above localities agree perfectly with soror, 

 Preston, which, however, Pilsbry considers synonymous with the Indian 

 coenopictus ; they certainly do not appear even subspecifically distinct. 



Subfamily VERTIGININAE. 



Genus Nesopupa Pilsbry, 1900. 



Subgenus afripupa Pilsb. and Cooke, 1920. 



Nesopupa {Afripupa) corrugata (Preston), 1912. 



Hab. L. Marques. Bandula Siding (Mcdowell). 



The local race is slightly shorter than that from the Victoria Falls, the 

 only other known habitat of this species ; the shells are perfectly con- 

 specific, however, and remarkable for the peculiar corrugated surface from 

 which they derive their name.
