122 PHYSICAL GEOGRAPHY. 



Meadow Mouse (A. austerus], is rather abundant over the State, 

 both on high bottoms and uplands. Still more abundant every- 

 where is the Western Prairie MeadoAv Mouse (A. curtatus}. The 

 Pine Mouse (A. pinetarutri), occasionally occurs along the Missouri. 



The Jumping Mouse (Zapus H'tdsonius], is found only in the 

 wooded portions of Nebraska. At least I have never met it any- 

 where on the prairies. 



The Musk Rat is found in almost every stream of the State, 

 and though much reduced in numbers by trapping still holds its own. 



The Porcupine is present in the State in small numbers. It is 

 the Yellow Haired Variety {Erethizon epixanthus}. 



The Hares are well represented in Nebraska. The Prairie Hare 

 (Lepus campestris), is found in central and western Nebraska. The 

 Varying Hare (L. Americanus), in some of its varieties, is common 

 in the State. The Gray Rabbit (L. sylvaticus), is still more abundant 

 than the former. The Jackass Hare (Z. caltotis}^ is abundant in 

 western and central Nebraska, and more sparingly as for east as 

 the Missouri. I have captured specimens within a mile of the Mis- 

 souri bottom. Cones and Allen give its habitat here only as west- 

 ern Nebraska.* 



The Insectivara are represented by only a few species. Five of 

 these are shrews, belonging to one genus, namely, Sorex pachvurus, 

 S. richa, S. Cooperi, S. Haydeni and S. Hoyi. I have not ascertained 

 their relative abundance. Another genus of shrews (Blarina) is 

 represented by three species, namely, B. talpoides, B. brevicauda and 

 B. exilipes. B. brevicauda is the most common and abundant, being 

 found almost everywhere in the State. 



The Moles are more abundant in individuals. One of them 

 (Scallops Argentatus) is abundant everywhere. Two others are 

 rare, namely, Condylura cristata and Uratrichus gibbsii. 



One Marsupial is rather common in the wooded portion of the 

 State. It is the common Possum {Didelphis Virginiana^] 



From the foregoing it is seen that at least eighty-two species of 

 mammals are native to Nebraska. 



BIRDS. 



The bird Fauna of Nebraska is remarkably developed. It is 

 particularly rich in genera, of which there are at least one hundred 

 and fifty-six in the State. The species amount to at least two hun-
