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, 

 Carpodacns ampins agrees with C. frontalis in the restriction of the 

 red in the male to sharply defined and limited areas, the coast form, 

 G. frontalis rhodocolpus, having the red " spread," as it were, over 

 the greater portion of the plumage ; Junco insularis 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. oregomis of the coast. Thryomanes hrevicauda is colored 

 more like T. heivicki leucogaster (the Upper Rio -Grande form) than 

 T. heioicki spihirus (the coast form) ; while Salpinctes guadahipensis 

 differs in the same way from S. obsoletus, w^hich, moreover, is 7iot 

 rejyresented 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, Carpodacns rhodocolpus being a case in point, this species 

 thus entering as a separating w^edge between G. frontalis and G. 

 amplusi Now very similar anomalous cases occur among Galapagos 

 birds, an entirely parallel instance being afforded by Dendra^ca 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, D. cestiva as a winter migrant, and 

 D. vieilloti as a resident — but never, as far as we know, D. 2)efechia.^' 

 Another quite similar case is afforded by Myiarchus 7nagni?'ostris 

 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 Dendrceca 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, but recognize in 

 them well-marked races, differing from each other about as much as the Gua- 

 dalupe birds do from those of the mainland.
