oaks, and other trees. There are several springs that flow during 

 the dry season, and in the arroyos bushes and trees fringe the 

 water-courses. " 



The next camp was in the Sal se Puerdes, at the same altitude 

 and not many miles distant from the Wakenakili Mountains. Sal se 

 Puerdes is described as a very broken and very barren mountain range ; 

 "a half day's hunt was necessary to find a flat place a few yards 

 square to camp by water. The country is very slightly timbered, 

 with nothing but bare rocks in the arroyo bottoms. The country, 

 in most parts, resembles a stone quarry." 



La Laja, where he spent the next three weeks (May 16 to June 4), 

 "literally means a flat ledge, and probably was so named on account 

 of the many flat rocks. It is probably the highest llano, mesa, or 

 tableland in the State of Jalisco, having an altitude of 9000 to 10,000 

 feet. It is situated between two sharp ranges of the Espirito de 

 Santos Mountains. There is no water in the dry season on the llano 

 proper, but there are many springs in the arroyos which never run 

 dry. It is timbered with pines, oaks, junipers, and many other 

 kinds of small trees. The nights are cool in summer, and light snows 

 occur occasionally in the winter months. Heavy rain storms send 

 bodies of water rushing down the valleys, twelve to twenty feet deep. 

 You will hear a roar for a few minutes and then comes a deluge of 

 rushing water, carrying with it even large boulders. " 



From La Cienega Mr. Batty proceeded to Tuxpan, about 150 

 miles southeast of La Cienega, and soon after began work in the 

 Sierra de Colima. His localities in this region are Tuxpan, June 

 2426; Volcan de Fuego, altitude 10,000 feet, July 531; Las Canoas, 

 on the tableland, about 40 miles west of Tuxpan, at an altitude of 

 about 7000 feet, August 4 to September 4, and September 20 to 

 October 2 (about 300 specimens); Artenkikil, an arroyo near Las 

 Canoas, September 5 to September 21; Volcan de Nieve, altitude 

 12,00013,000 feet, September 4-18 (about 100 specimens); Tanko 

 Riparti and La Joya are other localities on the Volcan de Nieve 

 where a few specimens were obtained, at altitudes respectively of 

 10,500 feet and 13,500 feet. Timber line on these mountains is given 

 by him as at about 13,000 feet. 



Mr. Batty 's collections in Jalisco were thus made at two points 

 in the State, (i) in northwestern Jalisco within a short distance of 

 the Tepic boundary, from December 17 to June 4, the mammals 

 obtained at the various points in this region where collections were 

 made numbering about 844; (2) in southern Jalisco, a little west of
