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 pee eveations carried on under the authority of the Fishery 
Board. 
It is now scale 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
