PEEFACE. 



This Catalogue contains an account of all the specimens of Seals 

 and Cetacea, and their bones, that are contained in the British 

 Museum, and a description of the specimens which are contained in 

 other collections, in order to show what are the species which are 

 desiderata to the Museum Collection. 



Man}- of the woodcuts are the same as were prepared to illustrate 

 papers published in the ' Proceedings of the Zoological Society,' 

 which have been kindly lent by the Council of that Society for the 

 purpose.
