5 pouces 6 ligaes = 475 m. m., consequently shorter than the

 hand is longer than the head and body together. 



At present there is one stuffed female of this species in 

 the Leyden Museum , labelled Brazil , as well as two skele- 

 tons from Surinam , presented by Dieperink.

 with dusky chestnut , the points being almost entirely white 

 for about 16 m. m. There are other quills which are white 

 at the base only and for the rest du.sky chestnut. Dorsal 

 parts of the tail conform to the back , for the rest covered 

 with short bristles and colored as in H. prehensilis. The

There are now of this species two stuffed females in the 

 Leyden Museum, one of them from Surinam ') (Dieperink), 

 the other one (from an unknown locality) died in the Zoological 

 Gardens at Rotterdam ; one skeleton taken from the latter 

 specimen, and the skull of the Surinam specimen. 



1) This must be the specimen, about which Waterhouse (in his excellent Work, 

 titled "A Natural history of the Mammalia, 1848, Vol. II, p. 414") remarks 

 "A specimen in the Leyden Museum, and which is labelled as coming from 

 Surinam, measures 20 inches in length, following the curve of the back; its 

 tail is about 33 inches in length, and therefore proportionately longer than 

 in the animals belonging to the Zoological Society; in other respects it does 

 not differ, excepting that the hairs on the tail are dusky brown." The figure 

 of the skull, o. c. , plate 18, fig. 2 being copied from Brandt's figure is that 

 of Hystrix Bratidiii mihi.
