of certain Birds of Cuba. 33 



et forma et cauda et ipse quoque pollex tuberculum nonnullo- 

 rum glirium pollicare referens, muris alicujus raajoris esse vide- 

 tur ? Ipsum gliribus nonnullis solenne superius labium fissum 

 redit in Simid Midd : sed omnium maximfe ultimam et gliribus 

 magis vicinam Simiam Jacchum putaverim, quae et ips^ caudae 

 prolixii hirsutie et scandendi more Sciuro propior est." p. 62. 

 Accordingly we learn that Sonnerat discovered an animal in 

 Madagascar, which was described by Gmelin as Sciurus Mada- 

 gascariensis ; which was by GeofFroy made the type of the genus 

 Cheiromys, or Handed Rat; and by Illiger in his Prodromus 

 placed next to the genus Galago, which is one of the Primates. 

 In the Regne Animal of M. Cuvier, p. 208, however, this Mon- 

 key-Squirrel goes back to its old place among the Rongeurs, 

 with a mere hint of its affinity to the Quadrumana ; which affi- 

 nity, however, is again reckoned so strong by M. de Blainville, 

 that in the third table of his Comparative Anatomy we discover 

 it occupying a place among the Primates, as the type of a group 

 to which he gives the name of Myspitheqites or Ape-Mice. Hence 

 I conclude it allowable to pass from the Primates to the Glires. 



Again : on looking among the Glires of Linnaeus in the 

 Systema Natures, ed. 12, I find an animal called Cavia Ca- 

 pensis, which obtained this place and name from Pallas, and 

 retained them with Erxleben and Hermann, although the latter 

 says : " E dens& summ^ affinium animantium turbA^ eligemus 

 Caviam Capensem, anomalum illud animal, quod ob privam in- 

 cisorum dentium formam ac situm, inferiorumque quaterna- 

 rium numerura et totam interiorem structuram separatum ut 

 constituat genus Linnaeo et Schrebero promereri visum est, 

 ast alio multo respectu Caviis Americanis, praeeunte Pallasio, 

 conjungi dignum. Sed connexum praeterea voluimus cum Bra- 

 dy pode, cui nescio qui habitus formaque corporis contracta, 

 digiti connatir magnusque costarum numerus cognatam faci-
