type-specimens to me — they have proved invaluable, and set 

 at rest what \vas previously very doubtful determination *. 



I shall first refer to four specimens in Tube no. 42, 

 Stettin Museum, labelled Vitrina cornea, Pfr. ; it was agreed 

 by us that they represented two different species, these I 

 designate : — 



A. Two banded shells, quite smooth. 



B. Two unhanded, with higher spire and globose. 



A. One of these compares so well wnth the shell figured 

 by Kuster as V. cornea, Pfr., pi. ii. figs. 31-33, p. 21 (1854), 

 in all respects, there appears to be every probability it is the 

 very shell from which the figures were made. A also 

 agrees with V. cornea, Mke., in British Museum Collection 

 from Cape Natal (Mas. Cuming), 3 examples ; also wdth a 

 single specimen from same collection (M. C.) and with three 

 others from Natal, No. 57, 1. IG. 14. 



B. Finest specimen, agrees best with K. natalensis, in the 

 British Museum Collection (M. C). 



The second tube from the Stettin Museum contained also 

 two species ; it had no number, but is labelled poeppigi, Mke., 

 Natal, a species figured by Kiister, pi. ii. figs. 13-15. Very 

 small with a distinct band : — 



a. One very small, banded (shell damaged). 



h. A large unhanded shell, quite 16 mnj. in major diameter 

 and of a different sha{)e, with high spire, figured. This I 

 consider the same species as B above, viz., natalensis, Krs., 

 it has microscopic longitudinal striation. 



Kerkophurus corneas, natalensis, and poeppigi are recorded 

 from the same locality, Port Natal, and are coast species. 

 Mr. Burnup, in a letter of 25th Anguist, 1911, says there is 

 considerable variation between such and those Maritzburg 

 species, 50 miles inland and 2000 feet above the sea ; we 

 must therefore take this into consideration when comparing 

 these species, and we must not go to Maritzburg in search of 

 K. Cornells — there we find a shell whi(;h is well known as 

 K. phadimus. We still want more material to see how far 

 the animals of the two places difi'er. 



Port Shep.stone is 75 miles south along the coast from 

 Port Natal or Durban, and we may assume that si)ecies of 



* It is with deep regret I have to record tlie death of Dr. Dohrn. I 

 wrote to him in January, and 80ou heard the s<ad news, but no details. 

 I have only very recently heard from the Trustees of the Stettin Museum 

 that he died at Florence on the 1st October, I'Jio, when on his waj- to 

 Naples. lie bad been much overworked in l'J12-l."i, first packing away 

 and moving collections, and then getting them rearranged in the new 

 buildings. As the letter says, his loss is irreparable.
