SMALL THRUSHES OF CALIFORNIA. 65 



mento Valley, in about the same latitude, by October first, 

 but the species is not usually numerous in the valley until 

 about a month later. Mr. Henshaw (Report AVheeler's 

 Survey, 1876), says none were seen on Mount Whitney 

 until the last of September. The migration was at its 

 height from the fifth to the fifteenth of October. 



Mr. Blaisdell first noticed this species at Poway on Oc- 

 tober 25, 1885. Dr. Cooper (Proc. Nat. Mus., 1879, p. 245) 

 first saw it on Santa Catalina Island, October 30, 1861. 

 Perhaps I should give full credence to Mr. C. II. Town- 

 send's Mt. Shasta record (Proc. Nat. Mus., 1887, p. 231), 

 although he did not get the individual seen July 25, 1883. 

 Mr. Brewster (Auk, Oct., 1888, p. 365) says Dr. Merrill's 

 Fort Klamath specimens were " Quite as gray as in average 

 Colorado specimens of audahoni.'" The wing of the female 

 measured 3.23; those of the three males 3.50, 3.55, 3.55, 

 being much smaller than my Calaveras County specimens of 

 T. seqiioiensis. I do not know that I have ever heard the song 

 of the dwarf thrush. The name of the dwarf thrush, nanus, 

 is very appropriate for this form. Mr. Nelson (Alaska Ke- 

 port, 1877-1881, p. 218) says: "Since the Unalaska thrush 

 was described, not a single specimen of any species of 

 Hylociclila has been found on this island by the various 

 naturalists who have visited its shores, a fact of itself cal- 

 culated to raise suspicion as to the correctness of the iden- 

 tification of Gmelin's name." Stability of ornithological 

 nomenclature is very desirable, but if there is the least 

 shadow of a doubt concerning the applicability of Gmelin's 

 harsh aoonalascensis to this thrush, the bird, the reader and 

 Avriter should have the benefit of the doubt, and nanus, 

 guttatus, minor, or almost any name should be substituted 

 for it. Dr. Cooper recently wrote me: ' ' I heard some years 

 ago from Mr. W. A. Cooper that the dwarf thrush had been 

 found breeding in the redwoods of Santa Cruz County. It 

 may be your form or some other." Dr. Cooper thinks the 

 Santa Cruz bird should be investigated, to which I cordially 

 assent.
