1915.] Chapman, New South American Birds. Ort 
forms (the female is smaller, instead of larger than the male, and is referable, 
probably to cauce) we may accept the male as the type of the race and make 
our comparisons with it alone. This specimen (No. 101309, U. S. Nat. 
Mus.) is labelled “Guayaquil, Ecuador, 1884; Dr. Wm. H. Jones, U.S. N.” 
It appears, however, that with other birds it was merely bought in Guaya- 
quil, and was doubtless collected in the higher interior. Dr. Richmond 
writes me from the National Museum that the collection presented by Dr. 
Jones was accompanied by a letter from which he sends me the following 
extracts: 
‘““... The birds alone I think are worth the freight of the consignment. I 
-rec’d these from Mr. Cartwright Agt. P. 8S. N. Co. Guayaquil as a gift. He is con- 
stantly receiving them from the interior of Ecuador,....”’ 
Dr. Richmond adds:— “On the invoice accompanying the above ietter, 
I find this note”’: 
‘“‘ ... Besides the above there are 80 birds from Mr. Cartwright’s collection at 
Guayaquil. These are all natives of Ecuador & found in various parts of the coun- 
try. Did not have time to obtain the native names nor the locality where each 
species came from.” 
Further evidence indicating that the bird came from the interior is 
furnished by the bird’s size which agrees with that of specimens from the 
Temperate Zone (see table of measurements beyond). In color, however, 
the type of equatorialis has the sides more heavily spotted, the back more 
barred than in any one of our four adult males from Mt. Pichincha and Mt. 
Chimborazo. It is my opinion, however, that the spotted sides and barred 
back of the type are due, at least in part, to its immaturity, and its almost 
wholly yellow (instead of basally yellow, apically plumbeous) mandible 
also indicates that it is not adult. : 
A male from Gualea, in the Subtropical Zone of the Pacific slope, while 
somewhat larger than specimens of cauce from the Cauca Valley, is much 
nearer to them, especially in the length of tail and tarsus, than to speci- 
mens of the Temperate Zone. It has the sides heavily spotted and 
appears to be fully adult. | 
Two males collected by Rhoads at Huigra (alt. 5000 ft.) are also nearer 
cauce in size but, as might be expected, show some approach toward the 
larger form of the Temperate Zone. One agrees closely in color with cauce 
and has the sides spotted, the other has but few spots on the sides and in 
color is therefore nearer the Temperate Zone bird. It can be exactly 
matched by specimens of ochracea! A specimen from Riobamba has the 
wing somewhat shorter than the average ‘Temperate Zone bird but has the 
long tail and almost immaculate underparts of that form.
