ASTACUS PALLIPES Lereboullet.' 



Neighborhood of Madrid, Spain (No. 4349. Mus. Comp. Zool.). These 

 Spanish crayfishes do not differ from French and English specimens of 

 A.pallipes. 



Doctor Mnni, 2 in a note on the crayfishes of Italy, shows that A.pal- 

 lipes is the common crayfish of that country, being widely distributed 

 through the Kingdom, as far south as Naples. A form found in the 

 province of Belluno, characterized by the presence of spines on the 

 outer margin of the antennal scale, is named by him Astacus pallipes, 

 var. fulcisicma. 3 ' 



Two specimens in the United States National Museum from Piobezi, 

 near Turin, vary in the direction of A. astacus. This variation is chiefly 

 shown in the outlines of the rostrum. 



The Astacus rugosus of Kafinesque, 4 presumably from Sicily, is quite 

 indeterminable, and the Astacus tomentosus of the same writer 5 is a 

 pure nomcn nudum.

A. P. Mnni 3 records Astacus astacus from Carniola and Goritz. One 

 young specimen from Belluno, northern Italy, is also considered by 

 Kinni to belong to this species.

 kevitch 7 has printed (in Russian) a fuller account of the Turkestan 

 crayfish, Astacus Jcessleri Shimkevitch.
