﻿crustaci;a malacostraca. 



Occurrence. The "Ingolf has not taken this species, but it is to hand from other sources. 



West coast of Iceland: Reykjavik, i specimen (taken by Hallgrimsson), and it lias been .secured 

 a number of times at the Vestmanna Islands and from tliere eastwards along the south coast of Iceland 

 to ca. i5',2""W. L. in depths from lo to ca. 60 fm. (A. C. Johansen, "Thor" 1903 and 1904, and "Be.skvt- 

 teren"). At the Fteroes it has hitherto been taken onl\- three times, nameh', in Kalbaks Fjord, 16—40 fm. 

 (Th. Mortensen); 4 miles east from Naalso, 80 fm. (Th. Mortensen), and 61° 56' N. L., 7^04'W. L., 30 fm. 

 ("Thor" 1903). 



Distribution. This .species is known from the Shetlands and the Hebrides (Xormani, further 

 south from the east and west coasts of Englaiul and east coasts of Ireland (various authors), north and west 

 coasts of France (Bonnier). It is said also to have been taken in the ^Mediterranean (Costa, test. Heller) and in 

 the Black Sea (Czerniavsky, test. (Jrtmann). To this it ma\" be added, that Heller wrote concerning 

 /-". iiiarmoreus Leach: "ist vielleicht bloss eine Varietat" of P. liolsatus\ A. Milne-Edwards & E. L. 

 Bou\-ier wrote in 1899: "Si, comme il y a lieu de le croire, le f. iiiarinorais doit etre identifie avec le 

 P. holsatus Fabricius", and they show that P. iiiariiiorciis is taken at the .\zores and state that it "habite 

 depuis le voisinage du littoral jusqu'a 60 m. — room, profondeur". I am unable to settle the question 

 whether P. uiariiiorcHs Leach is only a variety of P. Iiohatiis Fabr., but mention the statements cited 

 so as to .show so far as possible the present state of our knowledge, with special regard to the distri- 

 bution of this species to the south. 



P. Iiohatus has also been taken at the coasts of Belgium (v. Beneden), Holland (Herklots, test. 

 Ortmann), off and at the west coast of Jutland (Aleinert, Aletzgen, in the Skager Rak and "northern 

 part of the Kattegat as far as Varberg" (Meinert), at the south coast of Xorwa\' (G. O. Sars), lastly 

 Vesteraalen in Lofoten (Nordgaard). Tlie greatest depth I ha\-e found gi\-en is 70 fm., stated by 

 Meinert (1890). 



The most northerh- place from which the species was formerly taken was the Shetland Isles, 

 between 60 and 6i°N. L.; the statements given abo\-e of its occurrence not ouh' at the Fccroes but 

 also at the southern coast and the south part of the western coast of Iceland to ca. 64- 10' X. L. mean a not 

 unimportant increase to its distribution, and we have at the same time a new example of how southern 

 forms reach up to these places at Iceland. 



Remarks. The largest of the above-mentioned specimens came from the soutli coast of 

 Iceland; its carapace is 34 mm. long and 44' 2 mm. broad, which shows that it is indeed adult but 

 not a specialh- large specimen, as A. Milne-Edwards (1S61) gives respectiveh- 40 ami 53 mm. as the 

 two dimensions of the carapace.
