1 Station. 



Mariy specimens of T. lobatula sbowed a marked tendency to the carinate edge which 

 characterizes this species. The nearest approach to the type (which we regard as 

 having no zoological importance) was found at Stn. 8. It has been recorded by us from 

 Selsey Bill (ut supra) and from Clare Island (H.-A. & E. 1913, CI. p. 133).

9 Stations. 



Very generally occurring in company with the type, and exhibiting all the diversities 

 of this protean form. Excellent specimens of the long rectilinear form figured by
