142 MAMMALIAN DESCENT. [Lect. V. 



ADDENDUM TO LECTURE V. 



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

 give an exhaustive T)i1iliograpliy, M'hetlier zoological, anatomical, or 

 palcBontological, 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, 

 tlierefore, may be of use to the reaJer. 



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

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

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

 give a list of some of the pa])ers, memoirs, and larger Avorks that have 

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



The Catalogue of the Fossils in the Hunterian Museum belongs to 

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

 Owen's descrii)ti<in (witli splendid i)lates) of the extinct GJyptodon.
