70 Strecker — Reptiles and Batrachians of Texas. 



River, three miles north of Waco, and extends into Bosque 

 County, in a northwesterly direction. The elevation at China 

 Springs must be at least 250 feet higher than at Waco. This 

 section is hilly and broken. Holbrookia maculata lacerata Cope 

 is a species peculiar to it and my only specimens of Sceloporus 

 consobrinus B. & G. and Rhinochilus lecontei B. & G. are from 

 here. 



In McLennan County the main water-course is the Brazos 

 River, which runs through it in a southeasterly direction. On 

 the east side, about nine miles south of Waco, Tehuacana Creek 

 joins the river. The Bosque flows into the Brazos about three 

 miles north of Waco. This stream is formed by three branches, 

 the North, South, and Middle Bosque rivers. The North 

 Bosque is the principal one of the three, flowing through from 

 Bosque County on the northwest. 



Childress Creek, in the northeastern section, runs into the 

 Brazos River about six miles above the mouth of the Bosque. 

 Waco Creek and Barron's Branch, two small streams, flow 

 through Waco. The first mentioned is active about ten months 

 of the year, but the second is hardly more than a wet-weather 

 stream. 



The Bosque system has a number of small tributaries, includ- 

 ing Harris's, Bullhide, Flat-Rock, Hog, and Steele creeks. 



At one time there was a good-sized grassy lagoon known as 

 ' Dry Pond," about two miles east of Waco. During my first 

 few years of collecting this was my favorite resort. Here I col- 

 lected my first specimens of Elaps fvlvius and Tropidonotus 

 rhombifer and witnessed a migration of turtles. About seven 

 years ago the lagoon was drained and a levee thrown up and all 

 the glories of my serpent " Eden " have departed. 



A number of small natural and artificial lakes are scattered 

 through the county. Most of these are owned and kept up by 

 fishing clubs. 



The " Laguna Lake " mentioned several times in this paper 

 is a series of connecting lagoons in the northern part of Falls 

 County, not far from the McLennan County line. Through the 

 courtesy of Messrs. Polk Williamson, the former, and James H. 

 Harrison, the present, president of the " Laguna Lake Club " I 

 have been allowed to collect there on several occasions. 



I first began collecting reptiles in the fall of 1893, but it was
