INTRODUCTORY REMARKS. 



These Notes form a continuation of the series of papers which have 

 from time to time been published in Part III. of the Annual Reports of 

 the Fishery Board for Scotland. The purpose of these notes is to record, 

 in a more or less accessible form, some, at least, of the interesting 

 organisms that have been, and still are being, obtained in connection 

 with the investigations carried on under the authority of the Fishery 

 Board. 



It is now generally acknowledged that the Crustacea constitute 

 a considerable portion of the food of our food-fishes, and, as will 

 be shown in the sequel, several of the Crustaceans to be recorded here 

 have only so far been obtained in the stomachs of fishes ; a knowledge, 

 therefore, of the kinds and distribution of these organisms is necessarily 

 of more than merely zoological importance. 



During the past year a considerable amount of information concerning 

 the distribution of the Crustacea has been obtained, and a number of 

 species have been added to the marine fauna not only of Scotland but also 

 of the British Islands, while a few are apparently new to science. A 

 considerable number of rare species have been obtained in gatherings 

 collected by the " Garland " and forwarded to the Laboratory at Bay of 

 Nigg. Several rich gatherings of Crustacea were also collected by the 

 steam trawler " St. Andrew " of Aberdeen, which carried on some experi- 

 ments to the east of the Orkney and Shetland Islands during the months 

 of September and October last. One or two of the richest gatherings
