22. Cercoleptes caudivolvulus, Pall. 



One specimen from Sarayacn of the ordinary character, and two 

 from Balzar with remarkably short tails, the tails being about 11 

 inches long only, while the head and body in both measure about 16 

 inches. The skulls of these specimens are quite of the normal type ; 

 so that the shortness of their tails must be merely owing to in- 

 dividual variation. 



23. Tapirus ro^jlini, Fisch. 

 T. ecuadorensis. Gray. 



Two young specimens, Sarayacu. 



Mr. Buckley had obtained a fine series of about fifteen or sixteen 

 adult specimens of this Tapir ; but, unfortunately, before the skins 

 were prepared, a troop of native revolutionary soldiers put in an ap- 

 pearance and out off the hoofs of every specimen to make into 

 amulets, so that the whole series of skins was perfectly useless for 

 scientific purposes. Mr. Buckley was so vexed at this misfortune 

 that he did not even care to prepare the skulls, which would have 

 formed a very interesting set. 



24. Cariacus (Coassus) rufinxjs, Puch. 



Four specimens, three adults and one young, Sarayacu. 



25. Cariacus (Co^vssus) nemorivagus, F. Cuv. 

 Four specimens, two adult and two young, Sarayacu. 



26. SciURUS stramineus, Eyd. & SouL 

 One male specimen, Balzar. 



27. SciuRus jEstuans, Linn. 



Two specimens from Intac, and one from Balzar. 



Under the heading of S. griseogemjs, Gr., Mr. Alston, in his late
