6. Yesperugo georgianus (F. Cuv.\ Two specimens, Bee 

 Co., Texas, April, 1887, J. M. Priour. 



7. VesperugO hesperus (H. Allen). One specimen, skin and 

 skull, sex?, Presidio Co., Texas, Sept., 1887, Wm. Lloyd. One 

 specimen, skin and skull, sex?, Monterey, Mexico, May 30, 1889, 

 J. M. Priour. 



This species, originally described from Southern California 

 (Posa Creek and Fort Yuma), has since been recorded by Dr. 

 Merriam* from the little Colorado River, Arizona. The present 

 specimens show that it ranges eastward to Western Texas, and 

 southward to Monterey, Nuevo Leon. 



8. Antrozous pallidus (Le Conte], Two specimens, skins, 

 without labels, but probably from Presidio Co., Texas, or Nuevo 

 Leon. 



9. Scalops argentatus texanus, subsp. nov. 



Much smaller than either S. argenlatus or S. aquaticus, and bronzy chestnut 

 brown instead of silvery plumbeous, or brownish plumbeous. Above uniform 

 pale chestnut brown, with a decided bronzy lustre ; below darker, irregularly 

 varied with lighter areas, rather strong chestnut with patches of rufescent ash. 



Measuremer/ts (approximate from skin) : head and body, 100 mm. (3.94 in.) ; 

 tail, 24 (.95) ; hind foot, 16.5 (.65) ; fore foot, length, 18.8 (.74), breadth, 15.2 

 (.60). 



/Type f-fff, sex ?> Presidio Co., Texas, Sept., 1887, Wm. Lloyd.

This is apparently a small southern form of S. argentatus, from 



which it differs markedly in its smaller size (nearly one-third 

 smaller), and its strong bronzy chestnut coloration. The single 

 specimen is an adult, with the teeth much worn. The skull when 

 removed from the skin was found to be imperfect, the part pos- 

 terior to the middle of the orbits having been cut away. The 

 dentition in both jaws is intact, and the portion of the skull re- 

 maining presents nothing peculiar except small size. 



Since S. aquaticus is represented by a similar small form in 

 Florida (of which I have seen a number of specimens), and 

 Scapanus townsendii by a corresponding form in Southern Cali- 

 fornia (though neither of them have as yet been characterized), 

 it seems reasonable to consider the present specimen as a fair 

 representative of the Texan form of S. argentatus.
