Tardus aonalaschkce. —The arrivals of this species at Ha}^- 

 wards, as noted by Mr. Emerson, are: 



Dec. 18, 1880; none were seen in 1881; Nov. 28, 1882; 

 Nov. 1, 1883; Dec. 25, 1884; Oct. 16, 1885; Dec. 20, 1886; 

 Oct. 8, 1887. In 1885 they remained as late as March 28. 



I have seen them at Healdsburg, Oct. 5, 1888, and am 

 quite positive that I heard their single plaintive note among 

 madrone trees at Healdsburg, August 7, of this year.

 and they were from Saticoy, not Santa Cruz, wdience I sent 

 nests and eggs as of T, nanus (Vol. III., p. 20). I further 

 noted these points in Proc. Cal. Acad. Sci., Vol. VI, p. 190." 



Tardus sequoiensis. — I have compared five examples (four 

 males) of the thrushes taken in Monterey County, July, 

 1889, with the types of Mr. Belding's new T sequoiensis, to 

 which tlie}^ are probably referable, although not typical. 

 They were collected in heavily wooded, deep caiions, and 

 were found by quietly tracing the bird's song or by calling 

 them with a screaking sound made with the lips. The notes
