Weed — New Frogs from Minnesota. 109 



The measurements given are of the type, which is number 3065 of the 

 reptile collection of Field Museum of Natural History. This specimen, and 

 twenty paratypes, was received from New London, Kandiyohi County, 

 Minnesota. There are about eighty other specimens of this species in the 

 collections of Field Museum, from Spicer, Kandiyohi County. Minnesota; 

 Okabena, Jackson County, Minnesota; Rothsay, Wilkin County, Minne- 

 sota and Astoria, Deuel County, South Dakota. 



Rana burnsi is named in honor of Messrs. F. J. Burns and J. J. Burns, 

 whose courtesy and cooperation made it possible to get the specimens on 

 which this paper is based. 



Rana kandiyohi, sp. nov. 



Measurements of the type specimen: 



Width of head at rear of ear drum 24.0 mm. 



The web of the hind foot is variable. In the type it is continued as a 

 rather broad keel to the end of the longest toe. In one para type it reaches 

 about the middle of the distal joint of the longest toe. In the other para- 

 type it extends on the next to last joint of longest toe as a very narrow keel. 



Typical specimens of this species show a color pattern which suggests a 

 blending of Rana pipiens and Rana septentrionalis. It is as though the 

 black spots of Rana pipiens had been superposed on the mottled color of 

 septentrionalis. The spots are not as evenly rounded as in pipiens but show 

 a tendency to fuse with the mottlings between them. The vermiculate 

 mottlings are carried down on the legs and feet and are there combined 

 with a dark barring like that of especially dark colored examples of Rana 

 pipiens. 



The mottled color of the back is carried well down on the sides of this 

 species and fades gradually into the white of the under parts. The light 

 stripes along the glandular ridges are similar to those in Rana pipiens and 

 sometimes in Rana burnsi. 



The ground color is represented by small spots and lines between the 

 darker parts of the mottlings. It is about the same as in Rana pipiens. 

 Sometimes the mottlings are as dark as the spots. At other times they are 

 lighter. 



The type, Number 3066, Field Museum of Natural History, was received 

 from New London, Kandiyohi County, Minnesota. Two other specimens, 

 paratypes, came from an unknown locality in Minnesota. About thirty 

 other specimens were found in lots of frogs from Rothsay, Wilkin County, 

 Minnesota, and from Astoria, Deuel County, South Dakota.
