A comparison of this list of East Finmark Mollusca with 

 two Norwegian catalogues which I have previously published 

 will illustrate the changes in the Molluscan Fauna as we go 

 further north up the Norwegian coast (see Norman, "Mollusca 

 of t!ie Fiords near Bergen," Journal of Conchology, vol. ii. 

 1879, p. 8 ; and "A Month on the Trondhjem Fiord," Ann. 

 & Mag. Nat. Hist. ser. 6, vol. xii. 1893, p. 341).

In the course of a trawling-cruise round the coasts of this 

 colony undertaken by the Marine Department numerous 

 trials of the inshore fishing-grounds were made by Mr. Ayson, 

 Inspector of Fisheries, in the small chartered steamer the 

 * Doto.' In the course of one of these trials off Cape Saunders 

 a number of specimens of the fine new crab described in this 

 paper were obtained at a depth of about 60 fathoms and at a 

 distance of some 10 miles off shore. It is rather remarkable 

 that, though trawling has been carried on for a year or two 

 now, the same species should not, so far as I am aware, have 

 been met with agafn. There are no doubt periods of seasonal 

 migrations even of such slow-moving creatures as crabs, for 

 on a more recent occasion, but only once, the trawl brought 

 up a great many specimens of Priouor//i/nchus Edivardsii, a
