EINAR LÖNNBERG, MAMMALS FROM ECUADOR. 7 



two adult female skulls is resp. 161 and 167 mm. They are 

 thus longer than the adult male skulls of Pseudalopex cvl- 

 paeus andina Thomas from the bigh plateau of Peru and 

 Bolivia. The zygomatio breadth of the larger speoimen is 

 91, the same dimension of the smaller one 88 mm., thus the 

 same as in the male type of P. c. andina. 



When describing the latter Thomas pointed out, that it 

 was »most nearly allied to the northern Ps. c. reissii with 

 which it shares the normal-shaped skull, not disproportion- 

 ately elongated in the muzzle». In agreement with this T 

 should think it most suitable to consider andina as a sub- 

 species of reissii, as both share the more »thooid> appearance 

 of the skull in opposition to the more »alopecoid^ southern 

 forms. The smallness of the Peruvian form when compared 

 with the Ecuadorian one would then be analogous with simi- 

 lar conditions found among mammals belonging to other 

 groups as well, as will be set forth below. 



Tayra bärbara macleireiisis Lönnb. 



1 ^ -Vi 1921, near Napo river, 2000 f. alt. This speci- 

 men has quite the typical appearance with short hair and 

 verv dark almost black general colour of the body, into 

 which the dark umber brown of the head and neck gradu- 

 ally shades. There is a rather large triangulär yellowish 

 white spöt on the throat. The dimensions of the skull are 

 smaller than those of the type specimen, but as that was 

 old male and this one is rather young with tbe teeth not 

 worn, this fact may account for the difference. 



Lutra einerita Thomas or L. pariliiia Thomas. 



1 J" coUected ^o/^^ 1920 »near Gualea, altitude 5000 f.» 

 In the year 1914 Thomas described from Western Ecua- 

 dor a new species of Otter, which he named L. parilina. 

 This was said to be nearly related to the Otter from Merida, 

 Venezuela, which had been named L. emerita by the same 

 author 1908. The former should, however, differ from the 

 latter by its more broadly angularly projected nose-pad, its 

 narrower interorbital region and its slightl}^ larger carnassial.
