Mr. Oberthiir, Etud. Cotnp. Fasc. XIII. p. 33, suggests that tliis may be his 

 poirelli. The figure is so coarse and crude that it cannot be identified with 

 anvthing I know, though the outlines and size resemble poivelli ; but the very 

 careful description differs so from powelli, that I do not think it at all advisable 

 to unite them, but quote this as a species till we get Tunisian material for 

 comparison.
