48 REPORT ON ZOOLOGY, MDCCCXLIII. 



Sunclevall (1. c. p. 236) has accurately described the 

 " Cochon de terre/' found by Hedenborg in Sennaar, and 

 has distinguished it as Orycteropus athiopicus, from that 

 of the Cape. 



This description also I have already employed iu my Continuation, to 

 which I refer. 



SOLIDUNGULA. 



The article "Cheval," edited by Quatrefages in the 'Diction. Univ. 

 d'Hist. Nat.' iii, p. 476, is well drawn up. 



In the Jardin des Plantes, it appears to be decided that the " Kulan" 

 kept there is the Hemioims. Quatrefages adds the description of two 

 young ones born there, which is also inserted in the 'Institut.' 1813, p. 30. 



Savi has given some remarks on the anatomical structure and the 

 development of the horse's hoof. (Isis, 1S43, p. 412.) 



PACHYDERMATA. 



Owen has shown that the Tetracaulodon represents merely 

 the young condition of Mastodon giyanteum, and that the 

 Mlssurium also belongs to that genus. (Ann. Nat. Hist, 

 xi, p. 147.) 



Grant, ou the other hand, adheres to the separation of Mastodon and 

 Tetracaulodon, and assigns to the former 13, and to the latter 6 species. 

 (Ib. p. 479.) Hays also persists in distinguishing the two genera. (Proceed. 

 Amer. Philos. Soc. 1S43, p. 4-1.)
