I am not by any means confident that this form, or at any rate the 

 British specimens that have been assigned to it, can be separated from 

 Sp. margaritifera. Some of the Challenger specimens, notably those 

 Irom Kerguelen, differ strikingly from Williamson's figure; but then 

 Williamson had only a smgle specimen, and it may be questioned how 

 far it was typical.
