that such a mode of attack might be common among most, not all, 

 fishes. Of course, those which possess more effective weapons in 

 another part of the body would not resort to such a mode of 

 warfare. 



"3. As to the way in which carnivorous fish capture their prey, I 

 said, ' doubtless most do it by outswimming them,' and not that all do 

 this. In P. Z. S. for 1875, p. 545, I mentioned an observed fact of 

 an Antennarius multiocellatus angling for small fish. Of course no 

 one would ever imagine that the slow-moving fish mentioned by 

 Mr. Day would outswim their prey." 



1. Notes on the Anatomy of Tolypeutes tricinctus, with 

 Remarks on other Armadillos. By A. H. Garrod, 

 M.A., F.R.S., Prosector to the Society. 



[Received January 14, 1878.] 



The Society purchased, on the 3rd of October 1877, a young 

 female living specimen of the Apar {Tolypeutes tricinctus), which 

 was the first example of the species exhibited alive in the Gardens, 

 and probably the first ever brought alive to this country. It was in 

 bad health on its arrival, and, never recovering, died, without any 

 visible lesion, on the 27th of December following. Its death has 

 given me an opportunity of determining some of the most important 

 points in its anatomy, which may be accepted as a supplement to Dr. 

 Murie's valuable and elaborate memoir on Tolypeutes conurus in the 

 'Transactions of the Linnean Society' \ 



The measurements of the specimen under consideration are as 



follows : — 



inches. 



From tip of nose to base of tail 12*55 



Length of head 2'8 



Length of tail 2-1 



from which it is evident, on comparison with the table of measure- 

 ments of the specimens in the national collection given below, that 

 the individual was not adult, but fairly grown. 



The differences between the two known species of the genus Toly- 

 peutes are so slight that it may be worth while referring to them 

 before going further. It is to M. Geoffroy Saint-Hilaire that we 

 owe the discovery of the second species (T. conurus) ; and his most 

 lucid description is to be found in the ' Comptes Rendus' for 1874 3 . 

 Therein the history of the Apar is fully expounded, references being 

 given to all previous important accounts of the animal. 



It is in the central portion of the cephalic shield that the most 



important peculiarities are to be seen. The marginal plates of the 



posterior two thirds of this shield form a regular series, and enclose 



other larger plates — namely, a posterior median plate, followed ante-
