22. Oryzomys palustris (Harlan).O^Q specimen, $ ad., 

 Wharton Co., Texas, May 27, 1887, J. M. Priour. 



This specimen is provisionally referred to O. palustris, though 

 paler and grayer than any example in a large series from Florida 

 and Louisiana. It is much nearer this, however, than to O. couesi 

 from further south. 



23. Yesperimus leucopus texanus ( Woodho use). \-Qnz spe- 

 cimen, Bee Co., Texas, ? ad., April 21, 1887, J. M. Priour.

 specimens in the blue pelage, Oct., 1887, Wm. Lloyd. 



A single specimen from Tampico, Mexico, April, 1888, W. B. 

 Richardson, is also provisionally referred here. It lacks the skull, 

 and nothing is left of the tail but the unfilled curled-up skin. 



25. Geomys personatus True. 



Geomys personatus TRUE, Proc. U. S. Nat. Mus., 1888, p. 159. 



In 1888 Mr. F. W. True described a new species of Geomys, 

 based on two specimens from Padre Island, Texas. Mr. Sennett's 

 collection contains four specimens, from the same locality, col- 

 lected in February, 1887, by Mr. Priour. They include two very 

 old breeding females arid a half-grown young one, and a very 

 young one taken apparently when not more than a week or ten 

 days old. The two adults agree fairly well with Mr. T rue's de- 

 scription, but are apparently rather paler and more of an ashy 

 ecru tint above than his description seems to imply. The half- 

 grown example appears to agree exactly with his description. In 

 all the specimens the lower parts are white, as described by Mr. 



*The status of this form will be discussed at length in a later paper in the present volume 

 of this Bulletin.
