NERVOUS SYSTEM. VERTEBRATA. 233 



Considered as a whole, the brain of the Pangolin may be 

 regarded as a smaller and correspondingly-simplified copy 

 of that of the Three-toed Sloth. This fact, in view of the 

 marked contrast in the modes of life of the two animals, 

 must be allowed considerable, systematic importance*.

 (figs. 110, 111, 112, 113, 114, & 115). 



The brain is of approximately the same size and shape as 

 that of the Great Anteater, but its features present a most 

 striking contrast to it.

In neither of the specimens [in this collection] does the 

 posterior rhinal fissure join the anterior rhinal, but the two 

 fissures overlap (fig. 110) as they do in the Tapir (vide infra). 

 Sometimes, however, the two fragments unite to form a 



* When my memoir on the Edentate brain was written, I had not 

 examined a good specimen of the brain of Manis and had to rely on Weber's 

 account chiefly. I therefore saw no reason for associating Manis with the 

 other Edentates, so far as the structure of its brain is concerned. Now 

 that I know the brain itself, I quite agree with the conclusion drawn by 

 Windle and Parsons from myological studies (P. Z. S. 1899), and believe 

 that Manis shows undoubted affinities to all the other Edentates and 

 especially to Bradyptta.
