﻿CRUSTACEA MALACOSTRACA. n 



umberland (Norman), vS. E. from Yarmouth (IMetzger), Belgium (y. Beneden), on the English-Normandv 

 Islands (Koehler), Concarnean (Bonnier), Gulf of Gascogne and further south to the Canary and Cape 

 Verde Islands to 17"" N. L. (A. IM.-Edwards and Bouvier), It also occurs in the Mediterranean 

 (Heller, Gourret, Adensamer etc.) and is said to occur in the I51ack Sea (Czerniavsky, teste Ortmann). 

 Concerning its liathymetric distribution the following may be said. Bonnier states that it 

 occurs in deptlis from ca. 5 to 30 fm. on the coast of P^ritany; Heller gives 25 to 40 fni. for the 

 Mediterranean, Gourret ca. 10 to 33 for IMarseilles Bay, Adensamer 54 to 62 fm. for the Adriatic vSea, 

 CauUer}- 96 to 212 fm. for the CtuU of Gascogne, A. M. -Edwards &. Bouvier 41 to 223 fm. for several 

 places in the Atlantic (Cadiz to Cape Verde Islands), lastly 870 fm. for a .single .specimen taken 

 off Morocco. The last I consider as improbable until further information is forthcoming, and belie\-e 

 that it has arisen from some error or another (e. g. that the specimen has been in the trawl from an 

 earlier station). Apart from this it appears that the species occurs uniformly at all depths from ca. 

 5 fm. to a little over 200 fm., but that it is more rareh- fotmd in shallower water than 10 to 20 fm.

Distribution. All the localities of the "lugolf, Wandel and "Thor" lie west and south of Iceland; 

 the depth is between 265 and 691 fm., the temperature from 3-4" to 8-4'. The species was originalh- 

 taken in the warm area in the F^seroe Channel (W>v. Thomson), later vS. W. of Ireland, 250 fm. jPocock), 

 in the Gulf of Gascogne, 346 — 750 fm. {Cauller\), also in the Atlantic from the Ba\- of Bi.scay, Portugal, 

 Morocco, the Azores, the Cauar\- and Cape Verde Iskuuls in 120 to 1106 fm. (A. M.-Edw. i^c Bouvier); 

 in the Mediterranean at the level of Marseilles (A. M.-Kdwards) and a number of places in tlie .\driatic
