Tliis CNtrcnuly haiuls^oine species is most nearly allied to 

 ]'. C'«»</«<//i" (Beck) from tlie Philippines, and no doubt would 

 by some authors be placed in the genus llelicarion. Dr. 

 Boettger, who has obligingly examined our specimens, con- 

 firms our ojtinion as to its distinctness from any hitherto 

 known species. From r./*a;/)y/<)//V(Mt.'nke), which it resembles 

 in form, it ditlcrs in its larger size and smooth surface; from 

 V. cornea (Pfr.) , in addition to the above-mentioned particulars, 

 in being of a ditierent form, thicker substance, and possessing 

 a less oblique aperture. 



Vitrina zonamydraj sp. nov. 



V. testa globosa, convexa, robustiore quam V. an//iiZ« to, fuscescente, 

 pupra peripheriam obscure t'usco-cingulata; spira coiivexa, ampliore 

 quam in specie pra;cedente ( V. cinyidata) ; aiil'ractibus ventricosis, 

 laevibus ; apertura subrotunda.

This species differs from the preceding in its duller, more 

 robust substance, ampler convexity of whorls, difference in 

 colour, and extremely indistinct brown-red band, which is 

 barely visible without close inspection. It is easily distin- 

 guished from specimens of T'. natalensis (Kr.), with which, 

 however, it has affinity. 



Helix {Ptlla) Huttonice (Benson). 



Upon carefully examining numerous specimens under this 

 label in the National Collection, we were convinced firstly 

 that it is a true Vitrina, and secondly that three series of 

 shells from Port Elizabeth that we had at one time con- 

 sidered true species should be relegated to varietal rank as 

 follows : — 



Vitrina Huttonice (Bens.). 

 Yar. a. rufoflosa, var. nov. 



F. testa subglobosa, paUide hyalina, tenui ; spira convexa, conspicua ; 



anfractibus subconvexis, Igevibus, tenuissime arcuatim striatis, ad 



peripheriam rubro-lineatis ; apertura ovata.

This form may possibly have been confounded with F. 

 pcUicula (Fer,), a iiative of the ('ape region ; it is not diffi-
