Habitat. — Surprisiuo-ly little is known about the hibitat of this 

 form, particularly in the United States. In Burnet County. Tex.. 

 aularis is as common in the hills as it is alontr the streams and in the 

 lowlands. accordinf> to Strecker (1909«, p. 4), and " along the rocky 

 roadsides it is usually found in company with Crota'phytus coUaHs 

 and HoTbrool-ia trxa'tta.^'' The writer's field acquaintance with the 

 spotted lizard is entirely confined to Texas specimens. Near Lorena. 

 an individual was found among the green vegetation at the side of a 

 small pool of water in a stream bed. In San Saba, Reagan, and 

 Upton Counties, specimens were secured in semi-rocky, scarcely 

 sandy places where considerable shrubbery and some bunch grass 

 were present. The similarity of this habitat with that occupied by 

 the western pcrplexus is striking. 



In Reeves County, Tex., at a point north of the Barillo Mountains 

 and about 15 miles east of Balmorliea, (/alark was found in an 

 environment similar to the one just described in company with 

 perj)lexus^ with which it intergrades, and with Phrr/nosoma modcs- 

 tum. Ilolhrool-ia te.rana, and Cnemidoplioras tcsscJlatus tessellatvx. 



In Mexico gvJans probably occupies an interesting variety of habi- 

 tats, due to its plasticity. Specimens were found at the foot of Iron 

 Mountain near Durango on rather barren ground by Gadow (190G. 

 p. 339), who has written several additional notes concerning Mexican 

 specimens. In tlie district near Ixtlan the spotted race-runner was 

 found near the River Santiago at altitudes varying from 1,500 to 

 3,500 feet. This district is sandy, rather tropical, and produces much 

 vegetation (p. 341). In the Sierra de Nayarit of Jalisco five speci- 

 mens were collected at Ranchos in the walls of corrals at 4,G00 feet, 

 in open, treeless surroundings (p. 342) and nine were taken near 

 the town of Puebla, Puebla, on railway embankments. Sixteen spec- 

 imens, collected a few miles west of the town of Oaxaca, were on 

 open, rather barren terrain, or on the slopes of stony ravines with 

 scanty shrubs (p. 360), and northwest of Oaxaca others were taken 

 in shady gardens between stockades and cactus hedges. (Gadow, 

 1908, p. 270.) 



The Tres ^Marias and Isabel Islands, lying off the Avest coast of 

 Nayarit, Avere visited by Slevin (192G, p. 199). who wrote as follows: 

 •• This species was found to be very abundant on the beach of Isabel 

 Island -' * * * and it was also " a very abundant form about 

 the lower levels of ^laria Madre Island, wdiere it was found along 

 the roads, trails, and in brush thickets." 



Hahits. — The young and adults of gul<f/'is have different habits, 

 according to Gadow (1903, p. 123), who wrote that these lizards
