4—Bufo punctatus Baird and Girard 
We have at hand only five Arizonan specimens of this 
toad. Nos. 17581, 17582, and 20871 were collected at Cave 
Creek, Maricopa County, May 16-27, 1910. No. 33847 was 
found by Mr. Herbert Brown in the foothills of the Catalina 
Mountains, 18 miles northwest of Tucson, Pima County. No. 
35002 was secured in Ramsey Canyon, Huachuca Mountains, 
Cochise County, July 7, 1912. 
5.—Bufo alvarius Girard 
Thirty-one examples of this little-known toad are now be- 
fore us. Twenty-six of these (33728 to 33752 and 33799) 
were caught at Yuma, Sept. 10-21, 1912. Many of these are 
young, showing the characteristic spotted style of coloration 
which disappears with age. Nos. 13166 to 13168 were se- 
cured in Phoenix, July 10-12, 1907. Two very large speci- 
mens (Nos. 35322 and 35323) were collected on the desert 
close to Tucson, August 22, 1912. 
6.—Bufo cognatus Say 
Forty-six toads (Nos. 33753 to 33798) of this species were 
collected at Yuma, Sept. 10-21, 1912. We did not find this 
toad at Tucson, although it is known to occur there, but we 
have seen specimens from Phoenix. The Yuma specimens 
were caught at night under the electric street lights. 
7.—Scaphiopus couchii Baird 
This spade-foot toad was found by us only at Fairbank, 
Cochise County, where eight specimens (Nos. 35227 to 35234) 
were collected August 12-18, 1912. They were caught in the 
water in a cattle-guard on the railroad. This species is said 
to be common at Tucson. 
9.—Rana pipiens Schreber 
We have about one hundred and thirty adult specimens of 
this frog from Arizona, besides eggs and many tadpoles. Most 
of these are from the Santa Cruz River at Tucson, but the 
species was found also at Yuma, Yuma Co.; Oak Creek, Co- 
conino Co., Sept. 1-3, 1912; Cave Creek, Maricopa Co., April 
2—May 27, 1910; Phoenix, Maricopa Co., March 11-31,
