110 MAMMALIAN DESCENT. [Lect. IV. 



Professor AY. H. FloAver, LL.D., F.E.S., Pres. Z.S., read, at the 

 Zoological Society, on April 18, 1882, a very important paper, 

 entitled " On tlie Mutual Affinities of the Animals composing the 

 Order Edentata ; " this is to be found in the Proceedings of the Society 

 for that j^ear and month, pp. 358-367. 



The structure of the skeleton in that Order will be found described 

 in a valuable work by the same author, namely, his Introduction to 

 the Osteology of the Mammalia (London : Macmillan & Co., 1876) ; 

 and his article on the Mammalia in the new (9th) edition of 

 the Ericyclopcedia Britannica, vol. xv. pp. 317-457, will be found 

 of great service to the reader. 



The late Prof. Garrod, ]\I.A., F.E.S., gave a paper "On the 

 Anatomy of Tolypetdes tricinctus in the Proc. Zool. Soc, Feb. 19, 

 1878, pp. 223-230, figs. 1-3. 



A series of papers by the late Dr J. B. Gray, F.R.S., which ap- 

 peared from time to time in the Proceedings of the Zoological Society ^ 

 will be found very useful, especially as here and there excellent 

 coloured figures of the various types are given. 



I have found the following papers by that laborious zoologist of 

 great use to me in working at this group : — 



1. " On the Structure of the Pelvis of Chalmyphorus truncatus" 

 Proc. Zool. Soc, Jan. 13, 1857, pp. 8-9, figs. 1-3. 



2. " Revision of the Genera and Species of Entomophagous 

 Edentata, founded on the Examination of the Specimens in the 

 British Museum," Proc. Zool. Soc, April 8, 1865, pp. 359-386. 



N.B. — In the last two pages of that paper the Prototheria (Platy- 

 jnis and Echidna) are still classified with the Edentata, although 

 their very much lower nature must have long before been known to 

 Dr Gray. 



3. " i^otes on the Species of Bradypodidoi in the British Museum," 

 Proc Zool. Soc, May 2, 1871, pp. 428-449, plates 35-37, 

 figs. 1-6. 



4. " On the Short-tailed Armadillo (Midetia septemcincta)," Proc 

 Zool. Soc, April 21, 1874, pp. 244-246, plate 41. 



Professor Huxley, LL.D., Pres. R.S., in his Anatomy of Verte- 

 hrate Animals, pp. 330-341, gave the student a succinct and 

 useful account of the structure of these types. 



Also, in his paper on " The Evolution and Arrangement of the
