1901.] MOLLUSKS PROM THE PERSIAN OILF. <M3 



1 Introduction a l'etude des Mollusques ' l , and likewise referred 

 often to P. Fischer's ' Manuel de Conchyliologie,' 1887. For the 

 character* of the species we have to some extent followed Tryon's 

 ' Manual of Mollusca,' so admirably continued by Dr. H. A. Pilsbry, 

 but we have at all times allowed our own views fair latitude. 



Economy of space being imperative we have, excepting in a 

 few isolated instances, omitted all synonymy, but nave endeavoured 

 in every case to give the name sanctioned by the laws of priority.
