named should examine my numerous camera drawings of all 

 the forms under consideration (except, of course, laby- 

 rinthea), compare them with the types in the British 

 Museum, and generally consider the case of synonymy that I 

 had inade out. Their deliberations have resulted in the 

 following decision, dated at the British Museum (Natural 

 History), CromAvell Road, December 6tli, 1912 : 



'' We have examined the seven species named below,^ as 

 requested by Major Connolly, and after careful consideration 

 have come to the conclusion that, making due allowance for 

 variability, the species in question are all indistinguishable 

 from E. farquhari save in a few unimportant characters, 

 the general characters of the aperture and dentition remain- 

 ing the same in all seven.

I am deeply indebted to these gentlemen, for without their 

 co-operation my conclusions must have remained unconvincing- 

 through the possibility of the material studied by me being 

 wrongly identified. 



Major Connolly has been good enough to supply me with 

 revised measurements of all the types, which in some cases 

 vary considerably from those originally published; but it 

 seems to me more useful to give here a selection of dimen- 

 sions of specimens from the various localities, than to emend 

 those of the specimens originally described under names 

 which it is sought to show should drop out of use. To this 

 resolve, however, it may be well to make exception in the 

 cases of the original type of E. farquhari, and the shell 

 originally described as E. labyrinthea — the former because 

 it is the persistent type, and the original dimensions are 

 manifestly wrong, no specimen in the large series examined 

 approaching such an attenuate form as they indicate ; and 

 the latter because Major Connolly's measurement, if correct,

 ploca, E. oppugnans, E. berthse, E labyrinthea."
