Two specimens in the shells of Purpura armigera, Chemn. 



The so-called yellowish-white spots characteristic of this species 

 are blister-like in appearance, being everywhere more or less 

 raised above the rest of the surface. On the carapace and ambu- 

 latory legs they appear to be chitinous, and are easily perforated 

 with a needle point, whilst the dark red parts adjacent require 

 considerable pressure before the needle can be forced through. 

 On exposed situations subject to friction, such as the joints of 

 the legs, they become worn down level with the rest of the sur- 

 face, they then present an abraded aspect, being closely punctate 

 and devoid of the glossy surface common to the yellowish-white 

 blisters and the dark red calcareous portions of the body and legs.
