The late Dr. Axel Ohlin who as a zoologist partook 

 in Professor Dr. Otto NoRDE]srsKJÖLD's expedition to Tierra 

 del Fuego 1895 — 6, succeeded in securing three skulls of 

 the »Fox» »from the eastern Pampas of Tierra del Fuego». ^ 

 These skulls which låter were delivered to the R. Natural 

 History Museum in Stockholm where they now are kept, 

 belong, of course, to the species which has been named 

 Pseudalopex lycoides Philippi.^ As Philippi's description is 

 incomplete so far as there are no cranial measurements, 

 nor any other notes on the skull communicated in the same, 

 but such measurements certainly are of importance, not least 

 with regard to South American Canidce, I will take the 

 opportunity of filling this gap. This is the more important 

 in this case as the absolute measurements indicate the diffe- 

 rences between the species of Tierra del Fuego, and the one 

 of the mainland, generally known as Pseudalopex magellanicus 

 Gray which for a long time have been mixed up. The figures 

 of the adjoined first table indicate that these differences in 

 size are very considerable. In the three first columns the
