some are more oblong than otliers. Tlieir length varies t'roui .7-i to .70 of an 

 inch, auil their "xeatest breadth from .60 to .65. The ground -color is a red- 

 dish-white, profusely covered with blotches of purple, slate, reddish-brown,

The distinctive features of this race will be found indicated on page 141. 

 This form bears to the T. ludorkianus about the same relation that Harpo- 

 rhrjnch-us longirostris does to JI. rvfus ; and is hardly to be considered a dis- 

 tinct " species " from it. It shottld lie noted that in l)oth cases the length- 

 ened bill and deeper color belong to the liio Grande. It has not yet been 

 met with north of the I!io (irande, but doubtless extends into Texas. Noth- 

 ing is known of its habits.

Tliere are three strongly marked geographi- 

 Ciil varieties of "' Bewick's Wren," separable 

 by quite constant characters. Of these the 

 Mexican (Icvcogader) and the typical form 

 from eastern North America {bevnclcii) differ 

 most in coloration, while the western (spilu- 

 rm) is intermediate in this respect, but with 

 a longer bill than in tlio otlier two. The ])e- 

 culiarities of tlie three forms are expressed 

 on page 141.
