IT. 



Co mparison of tlw 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.
