Statiox No. TT. — Gardners Lagnna, Salton River, Lower Cali-

 No. 21(), 50 kilometers (37 miles) west of the Colorado River, and 168 

 kilometers (104 miles) east of the Pacific Ocean. Altitude of sta- 

 tion, 16 meters (52 feet). Camp was made in a dense thicket of tall 

 mesquites, on the north bank of a laguna a mile in length. There 

 were a number of other lagunas, large and small, in the vicinity. All 

 contained fishes and aquatic birds in abundance. Thickets of arrow- 

 wood bordered the stream, and mesquites, as usual, crowned the 

 neighboring sand hills, among which were areas of creosote and 

 greasewood bushes, sage brush, and desert weeds. Willows and an 

 occasional cottonwood tree bordered the stream. This camp was 

 occupied from April 18 to 27, 1894, by myself and assistants.

 lected specimens, among them examples of the wandering tattler, 

 tree swallow, and other interesting birds.
