Fyne, Mull, Skye, North Uist and Sutherland shire, the last 

 four localities being represented by only one or two records 

 each. It has been taken twice at the Orkneys. 



Finally a single specimen has been found on the coast of 

 NoHN^ay, near Bergen, but Appellof (1906) regards this as 

 a doubtful record. 



Irish Distribution. — It is found all round the Irish coasts, 

 but most plentifully in the south and west ; in the north it is 

 rare. It has been recorded from the following localities : South 

 coast : Youghal (Bell), Cove (Humphreys), Derrynane, Valentia 

 (Kinahan) ; west coast : Galway (Melville), Oranmore, Bally- 

 nakill, Aran ; north coast : Magilligan (Kinahan) ; east coast : 

 Lame Lough (Rankin), Dalkey Sound (Kinahan). 



It is common at Inishbofin, Co. Galway. 



On the Continent, and especially in France, Spain, and 

 Portugal, P. vulgaris, the " Langouste,'' is of great commercial 

 importance. It is fished on all the Atlantic and Mediterranean 

 coasts of the countries named. The fishermen use boats fitted 

 with large tanks in comniunication with the sea, and in these 

 the animals may be kept alive for any length of time desirable. 

 Some of the larger boats can carry eight or nine thousand living 

 Langoustes. There is also a thriving industry connected with 

 the species in Corsica, and on the Italian coasts. In Greek 

 waters, on the other hand, it is not fished to any great extent, 

 though occurring in large numbers. It is not held in great 

 estimation in this country as an article of diet, and most of 

 the specimens caught on the coasts of Devon and Cornwall 

 are sent to Boulogne. 



There is at present no regular fishery of P. vulgaris in Ireland, 

 the pots used for the capture of lobsters being too small to admit 

 full-grown "crayfish." The latter, when caught, are generally 

 found clinging to the outside of the pot. They are also taken, 

 not unfrequently, by trawels, and may often be seen exposed 

 for sale in Dublin. I understand that it is proposed to use 

 trammels for "crayfish" on the South coast. Trammels have 

 been found very eflective, especially if left in the water until the 

 first fish caught in them become somewhat decomposed.

This species is at present represented by a single male specimen 

 taken ofl the south-west coast of Ireland in 212-229 fms. It 

 is closely related to P. vulgaris, Latrielle, and also to a South 

 African species, P. Gilchristi, Stebbing. 



On the median dorsal part of the carapace there are two rows 

 of strong, well -developed spines. The rows begin at a point half- 

 way between the rostrum and the cervical groove, and extend 

 very nearly to the hind margin of the carapace. The part of 

 each row which lies in front of the cervical groove consists of
