142 MAMMALIAN DESCENT. [Lect. V. 



ADDENDUM TO LECTURE V. 



Here, again, I may remark that it does not enter into my plan to 

 give an exhaustive bibliograjDhy, whether zoological, anatomical, or 

 palseontological, but merely to set down the titles of such works as 

 have been most useful to me in my special line of research, and which, 

 therefore, may be of use to the reader. 



With regard to the fossil tyjDes that suggest so much as to the 

 develoi^ment of the existing ]Mammalia, of which I have spoken in 

 this fifth lecture, it seemed to me that it would be worth while to 

 give a list of some of the papers, memoirs, and larger works that have 

 come to hand during the last ten or a dozen years. 



The Catalogue of the Eossils in the Hunterian Museum belongs to 

 an older period ; but it is very valuable, for it contains Professor 

 Owen's description (with splendid plates) of the extinct Ghjxjtodon.
