et forma et cauda et ipse quoque pollex tuberculum nonnullo- 
rum glirium pollicare referens, muris alicujus majoris esse vide- 
tur? Ipsum gliribus nonnullis solenne superius labium fissum

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 Régne 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 Myspitheques or Ape-Mice. Hence 
I conclude it allowable to pass from the Primates to the Glires. 
-~ Again: on looking among the Glires of Linnwus in the 
Systema Nature, 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 densá summé affinium animantium turba eligemus 
Caviam Capensem, anomalum illud animal, quod ob privam in- 
cisorum dentium formam ac situm, inferiorumque quaterna- 
rium numerum et totam interiorem structuram separatum ut 
constituat genus Linnzo et Schrebero promereri visum est, 
ast alio multo respectu Caviis Americanis, preeeunte Pallasio, 
conjungi dignum. Sed connexum preetereà voluimus cum Bra- 
dypode, cui nescio qui habitus formaque corporis contracta, 
digiti connati, magnusque costarum numerus cognatam faci-
