young and not fully developed I am not quite sure about 

 the determination, but the colour generally, tbe long, distally 

 mottled tail, as well as the cranial characteristics agree with 

 Thomas' description of this species. 



Mariiiosa ef. marica Thomas. 



1 $ immature, Vu 1912, Alejandria, below Baeza about 

 5,500 feet altitude. 



This small specimen agrees on the whole with the spe- 

 cies mentioned above, but as it is immature, and the skull 

 somewhat broken, I cannot obtain full certainty about its 

 identity. In any case it must be nearly related to M. ma- 

 rica, but as it is somewhat darker and more brown it may 

 represent a geographic subspecies of the same. 



Caeiiolestes fuligijiosiis Tomes. 



1 (^ ad., Vu 1913, western side of Mount Cotacachi, 8,000 

 feet altitude; 1 ^ ad., ^6/^ 1913, road to Nanegal, about 6,000 

 feet; 1 $ ad. 27^ igjs, northern slope of Illiniza, about 12,000

 a moonlight night; just at the börder of the Paramo.» L

These specimens are all similar in colour, being uni- 

 formly brown above. This colour is something between 

 Ridgway's (1912) »bister and snuffbrown». The underfur is 

 lead grey (somewhat resembling Ridgway's »neutral gray»). 

 The lower side is much paler than the back and more greyish, 

 but the transition is quite gradual. The fur is soft and on 

 the back the longest hairs are about 9 mm, but the average 

 somewhat shorter (7—8). The tail is like the body darker 

 above than beneath, and the brown hairs of the upper side 

 are shorter and more scantily developed than the paler brown 

 to greyish hairs of the lower side. Thus the scaly whorls of 

 the tail are well visible on the upper, but fully covered on 

 the lower side. In the female 17 mm of the tip of the tail 

 is whitish. In one of the males and the female some long 

 hairs from the lower side protrude as a small pencil beyond 

 the tip of the tail. The fingers and toes are scantily covered
