ON THE SHETLAND CRUSTACEA, TUNICATA, ETC, 258 
IL. 
Co mparison of the Shetland Invertebrate Marine Fauna with that of 
other portions of the British Coast. 
No really satisfactory comparison can be made between the number of 
animals here reported on as inhabiting the Shetland Sea with those found on 
other portions of our coast. Unfortunately very little attention has hitherto 
been paid to any, except the larger and more conspicuous forms belonging to 
these classes. In order, however, that this comparison may be carried out as 
far as at present practicable, I give the following summaries of the most fully 
worked up local lists that I am acquainted with.
