PENNSYLVANIAN PIPIT. 
mandibles yellowish browii;, darker at the tip. The 
iris is said by Wilson to be a dark hazel. 
AVhen placed beside A. pratensis, there is a general 
resemblance between the two birds in size, colour, and 
markings. It differs, however, from A. pratensis in the 
following points: — The wing is half an inch longer, the 
hind claw shorter and more curved, the beak is stouter 
and broader at the base. Plumage of back is more 
uniform olive grey, and is less mottled, and on the 
lower part of the body there is a rufous tint more or 
less pronounced. 
The above description is taken from a female speci- 
men apparently in autumn plumage, and which is figured. 
It was kindly .'sent me 'by Mr. Sclater, the Secretary to 
the Zoological Society, to whom I have much pleasure 
in tendering my thanks for the assistance which he 
willingly affords me in the prosecution of this work. 
It is marked “Petaluma Car. Authy. Baird e. mus P. 
L. Sclater, No. 5415.” 
It has been figured as A. aquaticus by Audubon, pi. 
10, Orn. Biog., i, p. 49; Wilson, p. 89, pi. 42, fig. 4, 
(young.) The colours are much too bright in this figure 
— Edward’s Gleanings, ii, 185, pi. 297. 
I am sorry I have not an egg to figure. Brehm’s 
very clear description renders it, however, unnecessary 
for me to copy any of the three figures he has given 
in plate 35, fig. G. They are there represented as rather 
larger than those of A. pratensis, but thickly spotted 
with the same coloured dots on a similar ground.
