This species may be distinguished from C. carinatus, 

 Pennant, by its more rounded, less angular whorls, longer 

 and straighter columella, and yellow-tinged mouth. Between 

 the spiral ridges appear numerous fine lira?, crossed by fine 

 close-set lamina, from which character I propose the name. 



XLII. — On Butterflies collected between Chinde and Mandala, 

 British Central Africa^ hy Edward 31. de Jersey, Esq., in 

 March and April, 1899. By A. G. BuTLER. Ph.D., 

 F.L.S., F.Z.S., &c. 



The collection of whicli this is an account is not a very large 

 one, but contains some interesting forms of Acrcea, tliree 

 males of Mylothris Riippellii, and several other species of less 

 interest. 



Tlie following is a list of the species : — 



Nymphalidae. 

 1. Liiunas chrysijrpus, Linn. 

 S 6 ^ > Mandala, lltli April, 1899. 



2. Melanitis tsmene, Cram. 



(^ , between Chivomo and Katunga, 6tli April, 1899. 

 " Did not seem to leave dark thick bush ; had to be driven 

 out." 



3. Samanta perspicua, Trimen. 



S S, Mandala, 11th April, 1899. 



Both specimens belong to the typical wet-season phase, 

 but the irides of the ocelli are very narrow and smoky. 

 Prof. Aurivillius still doubts, as I did at first, tiiat S. Svnonsi 

 is the dry form of this species ; but we have an intermediate 

 example, received from Portuguese East Africa, and that, I 

 think, should settle the question beyond all dispute. 



4. Neoccenyra ypthimoides, Butler. 



(J c? ? 5 Mandala, lOth and 11th April, 1899. 



We recently had an example of A', victorice, Auriv., given 

 to us by the Rev. A. Dewar, who obtained it in company 

 with A', ypthimoides on the ISteveiison Poad on the phiteau 

 between Tanganyika and Nyasa ; it is quite distinct from 

 A', eatcvsa, having much more tiie outline of xV. Greyorii.
