(Devils River and Corns tock), Brewster (Boquillas and Terlingua), 

 and El Paso (El Paso). In the drainage of the Pecos River in Texas 

 this toad has been taken in Jeff Davis County (Fort Davis and Davis 

 Mountains) and in Reeves County (Cherry Creek). Farther north 

 there are records for Alamogordo in Otero County and Albuquerque 

 in Bernalillo County, N. Mex. 



Remarks. — The three co types of Bujo pundatus (U.S.N.M. No. 

 2618) were collected in Texas by John H. Clark, a member of Col. 

 J. D. Graham's party of the United States and Mexican Boundary 

 Survey, on the Rio San Pedro (Devils River), a tributary of the 

 Rio Grande. According to the original entry in the catalogue of the 

 division of reptiles, these cotypes were received from "J. D. G." 

 (J. D. Graham). The name of the collector is not given in the 

 catalogue, but Baird in his report on the reptiles of the United States 

 and Mexican Boundary Survey credits their discovery to J. H. Clark. 

 Inasmuch as they must have been collected not only prior to the 

 publication of the original description, but also while Clark was 

 working under the supervision of Colonel Graham, it will not be 

 difficult to fix the approximate date of collection. The party under 

 the direction of Graham followed well-known wagon roads used by 

 the United States Army in southern Texas. Leaving Indianola they 

 passed through San Antonio on their way to Fort Inge. From that 

 post the old road turns westward toward the Rio Grande and crosses 

 the Rio San Pedro (Devils River) near its mouth, and then follows the 

 valley of the latter for some distance before going across to the Pecos 

 River. The road followed the western bank of the Pecos River to 

 the mouth of Delaware Creek and then taking a more westerly 

 direction it passed Salt Lagoons Spring, and ended at Frontera (El 

 Paso, Tex.). Graham's party arrived at Copper Mines, N. Mex., 

 on August 2, 1851. Work on the boundary survey was com- 

 menced shortly after this date, and Clark accompanied Graham in 

 September, 1851, as far west as Santa Cruz in Sonora, Mexico. On 

 the return trip, Clark spent some time collecting in the vicinity of 

 Copper Mines, N. Mex. Maj. W. H. Emory was not directed to 

 proceed to El Paso, Tex., to relieve Colonel Graham until Septem- 

 ber 13, 1851. Clark received a new assignment from Major Emory, 

 and on February 12, 1852, we find him at the Presidio del Norte, 

 which was near the mouth of the Rio Conchos in Chihuahua, and in 

 May, 1852, at Frontera. The cotypes thus were collected during 

 the year 1851 and probably during July. 



Spotted toads are readily distinguished from other species by the 

 broadness and flatness of the top of the head, but vestigial cranial 

 crests may or may not be present. The general coloration of the 

 upperparts ranges from light reddish brown to olive or even malachite 

 green. The small sharply pointed warts on the upperparts are bright
