Bemarhs. — Though superficially resembling Neomi/s fodiens 

 the round-tailed water-shrew is easily recognizable by the 

 complete absence of any true keel on the tail. The slight 

 elongation of the hairs in median region which sometimes occurs 

 on terminal third of tail never results in the formation of a 

 definite keel similar to that of the related species ; while no 

 trace of such a structure is ever present on basal half of tail. 

 The smaller hind foot is usually diagnostic, though in this 

 character there is a slight overlapping between the two species. 

 Though in all essential respects trvie water-shrews, the members 

 of the round-tailed group (N. anomalus of Spain, N. milleri of 

 the Pyrenees, Alps and northern Hungary, and N. teres of 

 Asia Minor) are less highh^ specialized than Neomys fodiens. 

 Their habits, however, appear to be essentially similar to those 

 of the common species, as the two animals are found together in 

 localities where their ranges coincide.'""

* At two localities in the Pyrenees (I'Hospitalet, Ariege and Bareges, 

 Hautes-Pyrenees), where I found the two animals occurring together, both 

 were taken alternately in the same traps set at the edge of mountain 

 streams. In the original description of the species, however, I\Ir. r^Iottaz 

 observes (p. 23) that according to his observations the round-tailed animal 

 is the more inclined to wander away from the immediate vicinity of water. 

 The habits of N. anomalus in North Central Spain appear to be as strictly 

 ac[uatic as those of N. fodiens.
