To Cuthbert CoUingwood, M.A., M.B., author of Rambles 

 of a Naturalist on the Shores of the China Sea, Hon. Sec. of 

 the Liverpool Literary and Philosophical Soc, 1860-65, 

 must be assigned a distinguished place amongst the pioneers 

 of our local Natural History; and though his writings, 

 attractive in style as they are, indicate a compiler and a 

 chronicler rather than an investigator, he was a zealous 

 worker as well as a wide and an appreciative observer. 



In two papers published in the Proceedings of this 

 Society, 1863-4, on the Geological Fauna and the Historic 

 Fauna of the District, Dr. CoUingwood has quoted a very 

 large number of authorities, principally on the fossil remains 

 or recent occurrences of vertebrate animals. 



In June, 1859, September, 1860, and January, 1861, 

 Dr. CoUingwood published in the Annals and Magazine of 

 Natural History, three papers on the Nudibranchiate Mol- 

 lusca of the Mersey and the Dee, from which the following 

 list is taken : —
