that I examined had black roofs to their mouths, but there was much 

 variety in the colours and degrees of coarseness of their coats. * * * 

 Many Fuegian dogs are spotted and not a few have fine short hair, 

 but all resemble a fox about the head. * * * One brought from Tierra 

 del Fuego Mas white with one black spot, and very handsome; his size 

 was about that of a terrier, his coat short but fine, and his ears extremely 

 delicate and long, although erect;" the muzzle also is long, the tail 

 rough and drooping. 



Skull and Limh-botics. — In a recent paper. Professor Lonnberg 

 (1919) has given what appear to be the first published hgures and 

 measurements of the limb-bones and skull of this dog. His speci- 

 men was a skeleton obtained by Xordenskjold in 1895-96 during his 

 Tierra del Fuego expedition. As this author demonstrates, the skull 

 is that of a true dog, and shoAVS no relationship with the native canid, 

 Pscitdaloprx lycoidcs. A comparison of the cranial measurements 

 with those given for the Techichi of North and South America, shows 

 a very close approximation, amounting almost to identity. The 

 first lower molar in the Fuegian Dog seems smaller, however, 16.5 

 mm. in Lonnberg's specimen against 17.5 to IS. 5 mm. in the more 

 northern dogs. For better comparison, the following measurements 

 of the Fuegian Dog are reproduced from this paper (Lonnberg, 1919, 

 p. 11):- 



Condylo-incisive length 141 mm. 



Length of palate 71 . ;3 " 



Front of canine to back of m- 64 " 



Length of premolar* 15. 2 " 



Length of upper premolar-molar series. ... .51 " 



Width of palate outside m^ 52 . 6 " 



Zygomatic width 81 " 



Length of nasals mesially 46 " 



Length of lower mi 16. 5 " 



Length of humerus 105 " 



Length of ulna 125 



Length of femur 132 



Length of tibia 139 



l.scs. — The Fuegian Dog is acti\ e and strong in proportion to its 

 small size; quiet, faithful to its master, and able to withstand much 

 privation; A-igilant and extremely sly. It is capal)le of barking like 

 the European dogs. 



They are of invaluable service to their masters in hunting, particu- 

 larly in the pursuit of otters (Lutra fclina), which are assiduously
