Mr. P. L. Sclater on the Neotropical Pipih. 367 
web. This black patch is much increased in the second rec- ^ 
trix^ occupying more than half the web_, and leaving only a | 
smoky white line along the shaft_, which increases in breadth , 
towards the tip. There is a slight white tip to the third outer I 
pair, the rest of which, along with the six others, is black, 
the two middle rectrices being margined with rufous, like the 
back. 
The following are the principal measurements of the two 
specimens:—

In the latter specimen the tail-feathers are not quite fully 
developed, I think. 
Natterer obtained his specimens of this Anthus during his 
third journey, in the south of the province of Sao Paulo in 
July and August 1820, at Pescaria, Eio Verde, and Ytarare. 
He remarks that it frequents the grassy plains, and likes to 
run on the roads. ^ 
According to our present state of information, therefore, I 
am inclined to discriminate six species of Neotropical Pipits 
(not counting Anthus ludovicianus, which only occurs in Gua¬ 
temala), somewhat as follows :— 
a. Bill slender ; tail-feathers rounded. 
d. External rectrices smoky ; under surface of body 
tawny. 
1 larger, wing 3‘2 . 1. A. bogotensis. 
I smaller, wing 2-8. 2. A. cJiii, 
h'. External rectrices white ; under surface of body 
white or yellowish. 
d'. Very small, wing 2-5 . A. rufus, 
h". Larger, wing 3-0 to 3'2. 
I hind claw long and straight . 4. A. correndera. 
(hind claw short and curved . h. A. furcatus. 
h. Bill stout; tail-feathers pointed .. Q. A. nattereri. 
These characters may seem somewhat undecided perhaps, 
but not more undecided, I think, than the species themselves 
to which I have applied them.
