is their anomalous geographical relation to their mainland repre- 
sentatives, the latter being the Rocky Mountain or Middle Province 
races instead of those from the intervening coast districts / Thus, 
Carpodacus ampins agrees with G. frontalis in the restriction of the 
red in the male to sharply defined and limited areas, the coast form, 
G. frontcdis rhodocolpus^ having the red “ spread,” as it were, over 
the greater portion of the plumage ; J%mco insidaris is a perfect 
repetition of J. annectens so far as plumage is concerned (except 
that the shades of color are somewhat darker), and does not at all 
resemble J. oregonus of the coast. Thryomanes hrevicauda is colored 
more like T. hewichi leucogaster (the Upper Rio Grande form) than 
T. hewichi spilurus (the coast form) ; while Salpinctes giiadalnpensis 
differs in the same way from S. ohsoletus^ w^hich, moreover, is not 
represented at all in the coast district, except perhaps rarely and 
locally in Southern and Lower California. ' 
The peninsula above mentioned also presents in many respects 
closer affinities to the middle region than to the coast district, espe- 
cially in the fauna found at Cape Saint Lucas ; but on the western 
side many of the true Californian forms replace those of the Middle 
Province, Garpodacns rhodocolpus being a case in point, this species 
thus entering as a separating wedge between G. frontalis and G. 
ampins! Now very similar anomalous cases occur among Galapagos 
birds, an entirely parallel instance being afforded by Dendraeca au- 
reola, of which Mr. Salvin (1. c., p. 474) remarks : “The bird from 
the Galapagos [meaning the above-named form] is the same as that 
from Jamaica,* whereas on the intervening continent two other (so- 
called) species occur — namely, B. cestiva as a winter migrant, and 
D. vieilloti as a resident — but never, as far as we know, D. petechiaT 
Another quite similar case is afforded by Myiarchus magnirostris 
of the Galapagos, since Mr. Salvin says that “its nearest allies are 
perhaps the island races of the Antilles rather than those of the 
continent ; and in this respect the affinities of Bendroeca aureola 
are, to some extent, repeated ; but in the present case the specific 
characters of M. magnirostris are well defined ” (1. c., p. 492). 
In the paper above referred to, are incorporated notes by the col- 
lector, Dr. Habel, on the habits of the species ; and in these refer- 
^ We do not agree with Mr. Salvin in considering the forms of this species 
from the West Indies and the Galapagos absolutely identical, hut recognize in 
them well-marked races, differing from each other about as much as the Gua- 
dalupe birds do from those of the mainland.
