Merriam, from Arizona, is not easy to determine, since Dr. Mer- 

 riam's comparisons are exclusively with specimens of Z. rufus 

 from Connecticut. 



A series of 15 specimens from Arizona (Mearns Collection) 

 presents a wide range of variation in color, summer specimens 

 being more tawny than winter specimens, with the black spots of 

 the lower parts more vividly contrasted with the purer white 

 ground color. There is also much individual variation, especially 

 in respect to the distinctness of the face and head markings. 



Two specimens from Florida (Tarpon Springs) are, as com- 

 pared with northern rufus, very dark in general coloration, 

 especially over the hinder portion of the dorsal surface, and the 

 head markings are stronger. These represent a fairly recogniz- 

 able Florida form, provisionally termed "Lynx rufus var. florida- 

 nus Rafinesque" by Baird in 1857 (1. c., p. 9., in text). A single 

 specimen from Brownsville, Texas, is strikingly similar in general 

 coloration. Two specimens from the formerly so-called 'Neutral 

 Strip,' Indian Territory, are much more like the northern Z. 

 rufus. Two winter specimens from Montana have, in comparison 

 with all of the other specimens, a much longer, thicker, softer 

 pelage, as would be expected from the season and locality, but 

 they are also grayer and less strongly spotted. 



Doubtless the Lynxes of the widely distributed Z. rufus group 

 will be found separable into a number of more or less well-marked 

 geographical forms, when sufficient material for comparison is 

 brought together.
