130 THE NAUTILUS. 



close proximity with the Straits of Messina, a number of shells com- 

 mon at Messina were found at Taormina and Giardine. 



At Messina there is an excellent market, in which at 5 a. m. each 

 morning a surprising variety of fish are offered for sale. The early 

 start required is amply repaid. The octopus, Polypus vulgaris L., is 

 considered as an especial delicacy as food, both in Sicily and Italy. 



In preparing the following list I have determined, for condensa- 

 tion, to omit separate annotations. For convenience I have arranged 

 the Helices in alphabetical order, excepting Leucochroa. 



For the identifications I am indebted to Marquis Monterosato, Mr. 

 C. Payton Gwyer, Mr. E. A. Smith, of the British Museum, and for 

 difficult fresh-water species to Mr. Bryant Walker. The Malacolog- 

 ical Laboratory, Paris, has also given free use of its valuable library.
