j.8 CRUSTACEA MALACOSTRACA. 



West coast of Iceland: Reykjavik, the shore at ebb-tide; 4 spec. (A. C. Johansen). 



2 miles S. E. of Reykjavik, 6 fm., sand and stone; 2 very large spec. 



(A. C. Johansen). 



South of Iceland: Vestmanna Islands, in sandeel-net; i spec. (A. C. Johansen). 



Faeroes: two old specimens identified by Kroyer (taken by Nees). 

 Aadna Fjord, 015 fm., (R. Horring). 

 Head of Trangisvaag Fjord, o i fm.; i good-sized spec. (Otterstrom). 



Distribution. The species is known from the Shetlands and Norman writes that it is 

 "remarkably large" there. A. Milne-Edwards writes in his Monograph (1. c, p. 392) : "Cette espece vit 

 en grand nombre sur les cotes de France et d'Angleterre. On la rencontre snr tout le littoral de la 

 Mediterranee, peut-etre meme jusque dans la mer Rouge. Les Carcins Menades se trouvent sur les 

 cotes des Etats-Unis d'Amerique. Au nord, ils remontent jusqu'a la rner Glaciale". The last two 

 statements however require correction, but I have thought it right to cite what stands in the Mono- 

 graph. According to Gourret's "Tableaux comparatifs" (p. 44) the species is also found in the Black 

 Sea, at the coast of Portugal and at the Canary Isles, but I do not know the sources from which he 

 takes these data, of which especially the last is of interest. On the east coast of North America the 

 species according to Smith and M. Rathbun is distributed from ca. 43 2 /s N. L,. to 39V2 N. L,. It occurs 

 on all coasts of the North Sea, goes through the Sound and the Belts into the western Baltic (Meinert, 

 M0bius); on the west coast of Norway it goes to the North Cape (M. Sars, Appellof), but statements on 

 its occurrence at East Finmark and in the Murman Sea seem to be erroneous (Appellof). 



Kingsley (1878) writes: "This species is almost cosmopolitan in its range. It is found on the 

 Eastern Coast of the U. S., from Cape Cod to New Jersey (in 1879 he gives a still more southerly 

 locality, namely, Northampton Co. in Virginia), at Panama, in the Hawaiian Islands, France and Eng- 

 land, in the Baltic and Mediterranean, the Red Sea, Brazil, and, doubtfully, in Australia". In his work 

 on the Indian Crustacea Alcock states that he has seen a specimen from Ceylon; in 1902 it is noted 

 from Port Phillip, Victoria (teste Caiman). 



This distribution of a coastal form such as Carcinus Mcenas is extremely interesting; we know 

 indeed some few species of crabs and Stomatopoda which have just as great a distribution in the 

 tropical belts, but none that go so far north. 



Remarks. In the largest of the above-mentioned specimens from Iceland the carapace is 

 79 mm. broad and 62 mm. long; the distance between the tips of the second pair of legs is 234 mm.
