sowerby: new shells from port Alfred. 127 



Drillia hottentota, Smith, var. fuscescens, n.var. — The type of 

 D. hottentota is a white shell with a brown spire clearly defined from 

 the top of the body whorl, while the war . fuscescens is tinted all over 

 pale brown, with longitudinal streaks of darker brown. 



Bullia pura, Melvill, var. halteata, n.var. — This differs from the 

 typical B. pura, which is entirely white, in having a broad band 

 of pale bufi occupying most of the body whorl, and the lower part 

 of the upper whorls. 



Patella variabilis, Krauss, var. constellata, n. var. — The varieties 

 of P. variabilis are rather numerous, but I venture to propose a 

 name for one of rather remarkable character. It is of a dark brown 

 colour, with numerous yellow spots sprinkled over its surface, 

 having the appearance of a constellation. 



Fissurella mutabilis, Sowerby, var. aurantia, n.var. — This striking 

 variety is of a uniform orange colour. In form and sculpture it 

 does not difier materially from the type, though somewhat more 

 depressed.
