" One from Laguna, Lower California, February 1, 1883, is intermediate 

 between guttata and nana, but apparently nearer the former. 



"One from Casa Pintada, February 17, 1883, is quite typical nana."

Audubon's Thrush is represented in Mr. Frazar's collection by six skins, all 

 obtained on the Sierra de la Laguna between May 11 and June 8. One of 

 these birds (No. 14,515, 9 May 27, 1887) is small enough to be referred to the 

 so-called ^ ^ sequoiensis " of California, a form which does not seem to me worth 

 recognition. The others agree closely in size, as well as in every other respect, 

 with breeding specimens of auduboni from the Rocky Mountain region. 



This Thrush, which has not been previously reported from any portion of 

 Lower California, was found by Mr. Frazar only on the Sierra de la Laguna, 

 where it inhabited deep, moist, shady canons, and also, to some extent, dry 

 pine woods. It was not numerous, but was seen almost daily during May, and 

 up to the 9th of June when Mr. Frazar started for Triunfo. The males were 

 in full song, and there can be little doubt that they and their mates were set- 

 tled for the season and preparing to breed on this mountain. It is singular 

 that no form of Hermit Thrush was found on San Pedro Martir by Mr. 

 Anthony. 



H. a. auduboni breeds rather commonly in the mountains of California and 

 as far south as Orizaba in Mexico, while it has been taken in G-uatemala in 

 winter.

As Mr. Nelson has pointed out,^ the application of Gmelin's barbarous name 

 aonalascimsis (or aonalaschkae, as it is now generally written) to the Dwarf 

 Hermit Thrush is ill advised. Latham's description upon which the name is
