In tlie first part of tliis contribution, January 1912, p. 127, 

 under species of Kerkophorus : it has been pointed out to 

 me hy Mr. H. C. Burnup that the locality assigned to 

 tnunetus and poeppitjii, " Alexandra Junction, Maritzburg," 

 is misleading. I was under the impression that the two |)laces 

 were not far apart. What Mr. Burnup writes clears this up, 

 and I quote it in full : — 



" Poeppifji may certainly have been collected at both 

 Alexandra Junction and at Maritzburg, but it seems most 

 unlikely that inunctus should be found so far from the coast 

 as at Maritzburg. The alternative reading, and in the case 

 of inunctus the more likely (since you refer to o/je animal, 

 the type), is that Alexandra Junction is at or near Maritz- 

 burg. Tliis is quite wrong and the difference in climate, 

 with its vegetation, is considerable, Alexandra Junction being 

 on the coast a little al)Ove sea-level, aiid Maritzburg inland 

 at an elevation of over 2000 feet, with hills around, which 

 would fall into the same locality, rising to 1.500 feet further, 

 lilaritzburg, in a direct line, is about 40 miles N.W. from 

 Durban, and Alexandra Junction is nearly as far S.W. from 

 Durban. Since giving you the locality the name has been 

 changed from Alexandia Junction to Kelso Junction." 



With rejzard to coloration of the suture occurrino; in 

 specimens of P.hudsonice, mentioned m the first part of this 

 paper, p. 129: Mr. II. (J. Burnup, writing since its publi- 

 cation, agrees with me it is not a shell-character, and he 

 attributes to it another origin, which I think is a very likely 

 one and worth putting on record ; he says : — " My experience 

 teaches me that a similar feature, develops in other genera 

 besides Peltatinaj through a fracture occurring in the liver 

 (perhaps a small fragment being left in the apex) while with- 

 drawing the animal from the shell. A blood-like fluid oozes 

 from the torn liver, and capillary attraction draws it into the 

 almost margined suture, where, unless the shell is carefully 

 syringed, it settles, showing through the transparent shell as 

 a rufous sutural band." In illustration Mr. Burnup sends
