that tliere is no connection between the general colour and 

 the foot markings in tliis case. 



As far as these Weasels are concerned it is thus not 

 possible to base any racial differences on the degree of deve- 

 lopment of the light markings of the face and feet.

All these specimens are fully adult with the basicranial 

 sutures closed, and even the nasal sutures are closed in all, 

 exept n:s 8 and 9 among the males and n:o 6 among the 

 females, in which they are partly visible. 



With regard to the cranial dimensions I wish to make a correction 

 concerning the measurements of the »interorbital width» and the »post- 

 orbital constriction», which I have recorded for two Weasels from Ecuador 

 in my paper »Mammals from Ecuador and related forms», Ark. f. Zool. 

 Bd 8 n:o 10, p. 22, 1913, By an unfortunate lapsus these measurements 

 have been put 5 mm too high, depending upon my mistaking the mark for 

 10 mm as being that for 15 mm on my measuring instrument. Thus if 

 the measurements recorded are diminished by 5 they are correct. I deplore 

 this mistake and understand quite well that the dimensions as they were 

 printed appeared »incomprehensible.»
