298 LÖNNBERG, ON DASYPUS MINUTUS. 



ly alike») he did not think there was any reason to distinguish 

 this armadillo from Nahuel-huapi from Dasypus minutus. 



Thus, although this little armadillo does not prove to be 

 entirely new to science I think its aberrations however are re- 

 markable enough to be published, and I therefore intend to give 

 a short description of the animal together with some notes on 

 its anatomy, which also presents some interesting features when 

 compared with that of related forms. 



Total length including the tail between 32 and 33 cm. 

 Length of tail from anus about 10 cm. Length of carapace along 

 the curvature of the back about 18 cm. Length of skull 69 

 mm. Width of skull över the zygomatic arches 36 mm. Den-

The muzzle is tapering, and narrow at the end. The fron- 

 tal shield measures 5 cm. in length by 4 in breadth and is com- 

 posed of smooth plates. The central ones of these are blackish 

 with lighter margins. The lateral row is not so dark, and the 

 two or three foremost rows are quite yellow. There is no trace 

 of a nuchal band of plates. The first complete band of the 

 scapular shield is movable. Behind that are five immovable 

 bands. The scapular shield thus consists of six complete bands 

 in all. Anteriorly to the first complete scapular band is laterally, 

 on each side, an incomplete band of four plates, and on the 

 left side, anteriorly to that, a rudiment of two plates, but there 

 is nothing corresponding to this on the right side. There are 

 seven movable bands around the middle of the body. The pel- 

 vic shield is composed of 9 (or 10) united bands. The terminal 

 plates of the posterior scapular band, those of the movable bands, 

 and on the pelvic shield are large, and more or less falcate. 

 The base of the tail is naked on a space of l 1 /-2 cm. in length, 

 the other part is ringed with plates. The hairs on the back 

 are numerous and brown. They are most numerous behind the 

 movable bands. Through the eye goes a band of dark mouse 

 brown colour. The lower parts are grayish to dirty white. The
