12 ARKIV FÖR ZOOLOGI. BAND 14. N:0 4:. 



as n:o 7 is comparatively påle, although oaught in March. 

 It must also be observed that, if tbe specimens are arranged 

 according to colour, tbey form a continuous series without 

 any abrupt break between »påle» and »dark». 



The general colour of tbe palest specimens is most similar 

 to »snuff brown» 303,4 of Rép. d. Coul. by Oberthur & 

 Dauthenay. The dark specimens resemble very much the 

 coloured plate, which accompanies the original description of 

 this species\ and their body colour is as dark as the same 

 of a Miistela afjinis costaricensis from Cartago, Costa Rica, 

 in this museum. This colour resembles the darkest shade 

 of »chocolate» 343, 4 of Rép. d. Coul. The young specimen 

 is »raw umber» 301, 2 Rép. d. Coul. on its upper parts. 



The head is always darker, dark brown in the påle spe- 

 cimens, blackish in the dark. This dark colour continues in 

 some specimens somewhat on the upper neck and shades 

 there gradually into the body colour, but on the sides it 

 does not extend behind the ears, unlike the condition in M. 

 a. costaricensis. 



The lower side is white in J* n:o 2 and to the greater 

 part of 5 n:o 10, in which latter, however, the belly is some- 

 what buffish. The male mentioned is one of the påle spe- 

 cimens, but the female is dark. In the others more or less 

 of the chin and upper throat may be white, but the re- 

 mainder of the lower side is in the påle specimens buffish 

 to »buff» 309, 1 (Rép. d. Coul.), and in the dark »buff» 309, 1 

 to 309, 4, the richest colour is found on the belly. The 

 young specimen was when alive deeply orange coloured on 

 its throat and belly according to Consul Söderström's notes 

 on the label. 



White headmarkings are present in the specimens in a 

 variable degree as follows. 



Spec. 1, J* juv.: a frontal discontinuous spöt formed of 

 several white scattered hairs; a short temporai band of scat- 

 tered hairs on either side in front of the ear. 



Spec. 2, (^ ad. påle: a few white hairs in front of the 

 left ear, none on the right side. 



Spec. 3, J" ad. rather dark: a frontal band of scattered 

 hairs; white temporai bands on both sides, better developed
