the same as that of the two preceding species. It extends 

 from West Finmark along the coasts of Norway and Den- 

 mark (Sars, Stephensen) ; it is found on all the coasts of Great 

 Britain (Norman, Henderson, Kinahan, etc.), on the French 

 and Spanish coasts (Milne-Edwauds and Bouvier), in the 

 Mediterranean and Adriatic (Heller-Hansen), and at the Azores 

 and Canaries (Milne-Edwards and Bouvier). It has also been 

 recorded from Iceland. 



Irish Distribution. — The species is found all round the Irish 

 coasts. It has been recorded from Dublin and Belfast (Kina- 

 han, Thompson), from the south-west coast (Caiman), Clare 

 Island, Co. Mayo (Farran), and has been taken with very 

 great frequency by the Helga in the Irish Sea, and on the 

 south and west coasts. It was found plentifully at Ballynakill 

 and Bofin Harbours and in Blacksod Bay. 



Vertical Distribution. — G. nexa seems to be most plentiful 

 at depths of about 25-40 fms., but it may be found from 

 the shore line down to 260 fms. (Bonnier). The greatest depth 

 at which it was taken by the Helga was 199 fms. On the west 

 coast it was several times captured in more than 100 fms., and 

 was very common at about 40 fms. On the east coast it 

 occurs most plentifully in depths of about 20-30 fms. 



Galathea strigosa, Linne. 



Galathea strigosa, Bell, 1853. 

 Galathea strigosa, Kinahan, 1861. 

 Galathea strigosa, Bonnier, 1888. 



This may be distinguished from the other British species of 

 Galathea by its large size, the great length of its chelipeds, 

 furnished on both edges with strong spines, by the absence of 

 epipodites on all the pereiopods and by the form of the third 

 maxillipedes. 



Size. — ^Adult specimens may sometimes grow to a very large 

 size. One specimen found in Cork Harbour is 102 mm. long, 

 and individuals measuring 80-90 mm. are fairly common. 



General Distribution. — This species extends along the coasts 

 of the east Atlantic from the North Cape to the Canaries 

 and Azores (Sars, Appellof, Bouvier, Bonnier, etc.) It extends 

 extends into the Mediterranean and Adriatic (Heller, Senna), 

 and according to Heller has been found n the Red Sea. 



Irish Distribution. — Found all round the coast. 



Vertical Distribution. — It is frequently found under stones 

 between tide-marks, but also extends to considerable depths. 

 It is common in about 4-7 fathoms. One specimen was 

 taken by the Helga in 37 fathoms off the Calf of Man, and 

 Bonnier mentions a case in which it was taken in 328 fathoms.
