Introduction. 



The present paper is a continuation of the account of the 

 Irish Decapoda, begun by Mr. Stanley Kemp in "The Decapoda 

 Natantia of the Coasts of Ireland " {Fisheries, Ireland, Sci, 

 Invest., 1908, I. [1910]), andlhave tried to keep the scope of the 

 .work as nearly as possible the same, that is to say-, every species 

 discovered since the appearance of Bell's " British Stalk-eyed 

 Crustacea " in 1853 has been described and figured. This paper 

 includes the whole of the Palinura, Astacura, and Anomura, 

 with the exception of the Paguridea. The latter will be dealt 

 with in the next part, and a third paper will complete the account 

 of the Reptantia with the Brachyura. 



The classification adopted is that drawn up by Borradaile 

 (1907), as slightly altered by Caiman in the volume " Crustacea," 

 in Lankester's " Treatise on Zoology." 



The material on which the following account is based was 

 nearly all taken by the Irish Fishery cruiser Helga since the 

 year 1900. A few specimens taken within the Irish marine 

 area by the Danish Fishery steamer Thor are also included. 

 In the collection there are representatives of thirty-one species, 

 four of which are new to science, eleven new to the British, 

 and sixteen to the Irish marine fauna. The follow^ing is a list 

 of those new to the Irish area in which those which are also new 

 to British waters are marked with an asterisk : — 



^Polycheles typhlops. *Gastroptychus formosus. 



*Polycheles sculptus. Munida tenuimana. 



"^Polycheles nanus. *Munidopsis tridentata.
