minutely areolated calcareous crystalline but white-looking structure," and to which 

 Brady referred when stating that " the thicker portions of the wall contained a certain 

 amount of siliceous or calcareous sand," and, again, " calcareous spicules embedded 

 in calcareous cement." But these spherical bodies appear to be be quite distinctive 

 and peculiar to Carterina, and it seems probable that they may represent the initial 

 stage of growth of the fusiform spicules, and that increase in the area of the wall of 

 the test is obtained by the increase in the growth of these bodies in the course of their 

 development into the true spicules.

A single specimen only, noticeable on account of the extreme rarity of this typical 

 shallow-water species in what might have been expected to be favourable material. 

 It is recorded by Mobius from Mauritius as rare (from the intestine of Maretia 

 planulata).

 1 Station. 



One typical example. The species, first recorded by the late Dr. Chaster from 

 Southport, occurs rarely in dredgings all round the British Islands and we have also 

 found it in shallow water from the Maltese coast and from Tahiti. It therefore 

 appears to be widely distributed, though always rare.
