tion No. 102, on San Clemente Island." Plants, mollusks, fishes, 

 batracPiians, reptiles, birds, and mammals were collected at this 

 station from April 8 to 18, 1894, by myself and my assistant. 



Station No. 77.— Gardners Laguna, Salton Kiver, Lower Cali- 

 fornia. Station about 10 kilometers (6 miles) south of Monument 

 No. 216, 59 kilometers (37 miles) west of the Colorado River, and 168 

 kilometers (101 miles) east of the Pacific Ocean. Altitude of sta- 

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

 raesquites, 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. 



Station No. 78. — Laguna of -Salton River, Lower California. Sta- 

 tion about 2 kilometers (1.5 miles) south of Monument No. 217, 58 

 kilometers (36 miles) west of the Colorado River, and 169 kilometers 

 (105 miles) east of the Pacific Ocean. Altitude, 9 meters (30 feet). 

 I visited this place several times while camped at Gardners Laguna, 

 and, with Mr. Holzner, camped there April 27 to 28, 1894, and col- 

 lected specimens, among them examples of the wandering tattler, 

 tree swallow, and other interesting birds. 



oThe great majority of the plants gathered by the International Boundary 

 Commission, United States and Mexico, were personally collected by myself, 

 the rest as follows ; 



David Du B. Gaillard, first lieutenant, U. S. Army, member of the Interna- 

 tional Boundary Commission, frequently brought specimens of plants to the 

 collectors in the field during the progress of the survey. 



Prank Wagner, hospital steward, U. S. Army, collected plants along the 

 parallel 31° 47' and meridian section 108° 12' 30" (from El Paso, Texas, to 

 Monument No. 53) during the period from August to November, 1892.

 tween the San Pedro and Colorado rivers. 



Timothy E. Wilcox, major, U. S. Army, forwarded plants for the boundary 

 collection from Fort Huachuea, Arizona, during the summer and autumn of 

 1893. These were in addition to the extensive collections sent by him person- 

 ally, which latter were subsequently forwarded by Mr. P. V. Coville to Dr. N. L. 

 Britton, to form a part of the material upon which Doctor Britten's list of the 

 plants of the Huachuea Mountains was based. 



Ernest C. Merton, acting hospital steward, U. S. Army, collected plants 

 between the San Pedro River and Dog Spring, along parallel 31° 20' (Monu- 

 ments Nos. 98 to 5.5, from August 1 to September 23, 1803.

 considerable collection on the Huachuea Mountains, Arizona.
