RJdnolophus augur, sp. n. 



Short ^ta^no.s2s.-4 Apparently allied to Rh.ferrum-equinum, 

 but readily distinguished by its much smaller ears and 

 shorter tail. Forearm 54-57 mm. ^ 



Nose-leaves. — Horseshoe not covering muzzle laterally. 

 Sella pandurate, as in Hh. ferrum-equinum, but decidedly 

 narrower. Posterior connecting-process triangular, obtusely 

 pointed, its upper margin straight, shorter than the vertical 

 height of sella. Lateral margins of lancet deeply emarginate. 



Ears. — Not reaching tip of the muzzle, when laid forward. 

 Tip attenuated and acutely pointed. Outer margin strongly 

 concave below the tip of the ear. Greatest width of ear 

 equal to its length from notch on outer margin to tip. 



Wings. — General characters as in Eh. ferrum-equinuniy 

 but forearm on the average shorter, its maximum length 

 (57'2 mm. in a series of 15 specimens) being almost exactly 

 like mean measurements in Rh. ftrrum-equinum (57 mm., 

 31 specimens from Europe). 5th metacarpal slightly longer 

 than 4th. 2nd joint of 3rd finger almost twice the length of 

 2nd joint of 5th finger. In the folded wing, tip of 1st joint 

 of 3rd and 5th fingers opposite posterior point of elbow. 

 Plagiopatagium inserted at the tarsal joint.
