THE AMEBIC AN NATURALIST [Vol. XLIII 



ther learned that the coming of the cattle meant food for them, 

 hence they would meet the cattle in the shallows and follow them 

 to deeper water. The act of these fishes leaping to secure flies 

 from the sides of cattle is so unusual that it is deemed worthy of 

 notice and it is hoped that the incident may be of service to 

 those interested in animal behavior.

NOTICE OF A NEW CAMEL FROM THE LOWER 

 MIOCENE OF NEBRASKA 



In the autumn of 1906, the writer found a nearly complete 

 skeleton of a camel, in the Lower Harrison Beds, near Agate, 

 Sioux County, Nebraska. The skeleton is finely preserved and 

 articulated. It had apparently been washed into a heap while 

 the muscles still held the bones together, for it is literally tied 

 in knots. On this account it has only been partly removed from 

 the matrix, and so a complete description is deferred. 



The type (No. HC125, private collection of the writer) is an 

 adult animal, and consists of a complete skull and jaws, a 

 practically complete vertebral series, fore limbs and feet, pelvis, 

 sacrum, and the greater portion of the hind limbs and feet. 

 The latter were damaged by erosion. It is referred to the genus 

 Oxydactylus, and the specific name of Campestris is proposed. 



It is apparently closely related to 0. longipes, 1 but is a much 

 smaller and somewhat less specialized type. This seems the 

 more natural when we remember that O. longipes was found 

 in a somewhat later horizon. The skull in general contour is 

 very similar to 0. longipes, but exhibits some distinct features. 

 The upper incisors are proportionally slightly larger than those 

 of 0. longipes, the third incisor being a little larger than the 

 canine. The diastema separating these two teeth is relatively 

 shorter than in the latter, and the facial portion of 0. campes- 

 tris is relatively shorter. The premaxillae are separated at 

 the proximal extremity by an unusually large U-shaped open- 

 ing, 8 mm. wide and 10 mm. long. P 2 and P 3 are slightly more 

 robust in the present species. The limbs are long and slender, 

 though much shorter than those of 0. longipes. The meta- 

 carpals are entirely separate. On the sides of the proximal end
