Remarks about Coatis. 

 Since the above already was printed the Museum has 

 crratefuUy received from Consul L. Söderström some more 

 specimens of mammals, concerning some of which I feel 

 myself obliged to make the following remarks. 



Two of these specimens are Coatis representing two dif- 

 ferent forms. One of these has, in spite of its greater con- 

 dylobasal length (110 mm.), a narrow palate and a narrow 

 »pinched in» snout (breadth across p^ 19 mm.). It is there- 

 fore possible, that it belongs to Nasua quichua jivaro Thomas 

 as its cranial dimensions are rather similar to those recorded 

 for this species, f. i. a comparatively broad interorbital 

 region 24, 1 mm. etc. The teeth are, however, rather large, 

 p^—m^ measuring 21,5 mm. Against an identification with 

 N. q. jivaro speaks also the colour of the animal, which is 

 whoUy black with the following exceptions: chin white, 

 throat brownish white, and from the same runs a buffish 

 band below the ears some way backwards on the sides of 

 the neck about half way to the shoulders; on the crown 

 some scattered buffish hairs, and the forehead somewhat 

 grizzled with grey, snout not grizzled but more brownish. 

 The white orbital spöts present, the postorbital well defined 

 and round, the supraorbital is somewhat diffuse and the 

 suborbital rather small. Tail entirely black without rings. 

 It is possible that this specimen is melanistic, but against 

 such a supposition speaks the well marked pattern of the 

 head with the light orbital spöts etc. The specimen is a 

 female collected ^0/7 1920 near Baeza at an altitude of 5,500 

 feet. As only one specimen is at hand I prefer to leave the 

 question about its exact identity open until more material 

 also of the male sex can be obtained, but it is no doubt a 

 member of the N. montana-quichua group. 



The second specimen is quite different, but it is evi- 

 dently a member of the Nasua nasua group, no doubt a 

 fullgrown male of the same race as the young one mentioned 

 above p. 33. As it, however, differs from the material of 

 this group from different parts of South America, which I 

 have had the opportunity of studying, I must consider it as 

 a separate western subspecies, which I venture to name:
