We have a skeleton of this species, which was purchased of Mr. 

 Bartlett as " the Square-spined, not Crested Porcupine," but unfortu- 

 nately the skin was not preserved. 



I ought in justice here to remark, that Edward Gerrard, who has 

 the preparation and the care of the skeletons in the British Museum 

 collection, and Mr. Bartlett both informed me there were osteological 

 distinctions between these very distinct species. 



3. Atherura, Cuvier. 



Tail elongate, tapering, ending in a tuft of peduncled, compressed 

 spines. Skull elongate, rather suddenly narrowed in front, rather 

 depressed and flattened above. The nasal moderate, not reaching 

 to the front edge of the orbit. The intermaxillary rather narrowed 

 behind, square at the hinder end. The malar bone broad in front, 

 subtriangular, very narrow behind. The palatine foramen rather 

 far apart, linear and rather diverging behind. The grinder subcy- 

 lindrical. The upper front one with two large folds on the outer 

 side, reaching nearly to the inner edge, and with a smaller fold on 

 middle of the outer, and three similar folds on the hinder edge ; the 

 other upper grinder with two grooves or folds on outer edge, and one 

 on the middle of the inner : these grooves become isolated, oblong 

 rings of enamel as the teeth become more worn : the fold on the 

 inner side of the last grinder is most distinct. Palate truncate 

 behind.
