We are indebted to our friend the Rev. H. W. Crosskey, 

 F.G.S., for the opportunity of publishing this list, which, 

 though it does not strictly fall within the scope of the present 

 paper, is well worthy of comparison with the British lists. It 

 will be seen that all the species are known as inhabitants of 

 the British seas, more particularly of those washing the north 

 of Scotland and Shetland. Besides those given in the list, 

 there were amongst the specimens examined only one or two 

 unknown or of doubtful identity. These dredgings were ob- 

 tained by Mr. Lamont in his Polar Expedition of 1869, and 

 were by him obligingly handed to Mr. Crosskey.
