about this locality were extensively covered with unusually luxuriant woods 

 of cedar and pinon, among which Gymnokitta ajanocephala and Cyanocitta 

 ivoodhousii were more abundant than we had ever seen them elsewhere. 



CorvHs carnivorm and Centrocercus urophasianus were also abundant. 



34. Deep Creek, Northwestern Utah (October 5, 1868). — At this point 

 of our route, the nearly level sage-brush plain was intersected by a narrow 

 valley considerably below the general level, through which flowed, with a 

 sluggish current, a very narrow but remarkably deep creek, a tributary of 

 the Great Salt Lake. The banks of this creek were lined with rushes, 

 while in the valley itself were willow thickets. The principal birds 

 observed here were the following: — 



Amphispiza nevadeusis. I Melospiza lincoliii. 



Zonotrichia intermedia. | Telmatodytes i)aludicola. 



Melo.spiza fallax. j Geotbl.ypis tricLas. 



35. Vicinity of Salt Lake City, ZJtoA' (May 20-June 1, and June 14-21, 

 1869). — Owing to its diversified character, the vicinity of Salt Lake City 

 proved exceedingly favorable to the objects of the exploration ; the scrub- 

 oaks of the hill-sides, the luxuriant and varied shrubbery along the stream 

 in City-Creek Canon, the meadow-lands, both wild and cultivated, between 

 the city and the lake, the tule sloughs along the Jordan River, and the 

 extensive marshes about the lake-shore, having each their peculiar species> 

 besides those found in the sage-brush, and others of general distribution. 

 The species noted in the vicinity of Salt Lake City during the months of 

 May and June were those given in the annexed list, most, if not all, of them 

 having been found breeding in the neighborhood. The asterisk placed in 

 one or more columns after the name of a species indicates its center of 

 alnindance, the columns representing the following types of localities : — 



1. Sage brush plains and mesas. 



2. Meadows, chiefly toward the lake. 



3. Tule sloughs and marshes near Jordan River. 



4. Open i)onds, shore of the lake, etc. 



5. Thickets ahjng the streams, valley, and lower part of City Creek CaBon. 

 G. Scrub-oaks, slopes of City Creek Canon.
