the eastern toad in the structure of the bony crests and in the 

 shape of the paratoids. 



Woodhousii is less common in Bexar County than either 

 wdliceps or compactilis. I found only two specimens in the 

 Marnock collection. A specimen from San Antonio is in the 

 Scientific Society Museum and Louis Garni included it in his 

 list of San Antonio amphibians. I personally collected two speci- 

 mens along the San Antonio River, several miles from the city. 



9. Bufo compactilis Wiegmann Spadefoot Toad 



Bufo compactilis Wiegmann, Isis, 1833, p. 661 



This species and Bufo valliceps are the most abundant toads 

 in the vicinity of San Antonio. Numerous specimens were in 

 the Marnock collection and others have been collected by Hur- 

 ter, Garni and the writer. Under dead branches in a flat along 

 the Salado River, I found a large number of young specimens 

 only about an inch in length. It is usually abundant in damp 

 weather. It breeds in temporary pools and in its general 

 habits is more like a Scaphiopus than a true toad. 



10. Bufo debilis Girard Little Green Toad

1854, p. 87. 

 Louis Garni found this interesting little toad common on 

 the areas around the St. Louis College buildings during the heavy 

 fall rains. He also collected several in the college natatorium. 

 The four specimens he presented to the Baylor Museum are 

 the largest in the collection, being almost as large as average 

 sized Bufo punctatus. Adult specimens from Helotes, collected 

 by Marnock, are hardly more than an inch in length. 



11. Bufo punctatus Baird and Girard Spotted Toad

This toad is closely related to Bufo dsbilis but its habits 

 are different from those of that species. Debilis prefers open 

 country, usually mesquite-covered flats, and breeds in ditches 

 and wayside pools. Punctatus is partial to rocky localities, es- 

 pecially high bluffs enclosing small streams. Here it breeds in 

 rockbound pools. I have found specimens under rocks on the 

 tops of cave-lined bluffs during the excessive heat of midsum- 

 mer. Punctatus occurs in suitable localities throughout Bexar 

 County. I found six from Helotes in the Marnock collection; 

 two of these were unusually large. Edgar and I found an 

 adult under a stone on the side of the Babcock road. 18 miles from
