142 MAMMALIAN DESCENT. [Lect. V. 



ADDEXDUM TO LECTUEE V. 



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

 give an exhaustive bibliography, 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 types that suggest so much as to the 

 development of the existing Mammalia, of which I have spoken in 

 this fifth lecture, it seemed to me that it would be worth whUe 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 Fossils in. the Hmiterian Museum belongs to 

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

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