110 MAMMALIAN DESCENT. [LECT. IV. 



Professor W. H. Flower, LL.D., F.R.S., Pres. Z.S., read, at the 

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

 entitled " On the Mutual Affinities of the Animals composing the 

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

 for that year 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 Encyclopaedia Britannica, vol. xv. pp. 347-457, will be found 

 of great service to the reader. 



The late Prof. Garrod, M.A., F.R.S., gave a paper "On the 

 Anatomy of Tolypeutes tricinctus in the Proc. Zool. Soc., Feb. 1 9, 

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



A series of papers by the late Dr J. E. 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 Chalmyphoirus 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- 

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

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

 Dr Gray. 



3. " Notes on the Species of Bradypodidce 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 (Muletia septemcincta)" Proc. 

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



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

 brate 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
