Mr. W. H. Benson on some new Land Shells, 435 



577 a. Suppl. He has favoured me with a copy of his diagnosis, 

 from which I am enabled to state that it has no close relation- 

 ship with the present species.

A single specimen was found by Mr. Layard with Bulimus 

 compressilabris. It belongs to the aciculoid type, and is de- 

 ficient in the lucid transparency and peculiar slenderness of 

 Ach. Spiculum. The proportions of these two shells differ from 

 those of their allies, A. Acicula and Hohenwarti, neither of which 

 can compete with the new species in slenderness.

 cida, sutura impressa, apice obtusiusculo ; anfractibus sub quinque,

There is some indication of a fourth tooth above, on the palate, 

 in the only specimen received, but it cannot be made out di- 

 stinctly. The shell occurred in company with Achatina Spiculum.

Three specimens of this singular Pupa were found dead under 

 a rock by Mr. Layard. The specimen sent to me is much
