8o Field Columbian Museum — Zoology, Vol. i. 



3. THE FOLLOWING SPECIES WERE CONTAINED IN A SMALL COLLECTION 

 FROM YUCATAN, OBTAINED BY MR. H. H. BROWN AND PRESENTED TO 

 THE MUSEUM BY MR. C. B. CORY. 



Oryzomys — ? 



Two males without skulls, therefore it is impossible satisfactorily 

 to determine the species. 



Sciurus yucatanensis Allen. 



Two examples of females from Rio Lagotos and San Felipe. 



This form described as a sub-species by Mr. J. A. Allen presents 

 such a different appearance from the common species, S. caroii- 

 nensis, and has so little in common with that animal, that I deem 

 it entitled to specific rank. 



Mus musculus Linn. 



One female from Rio Lagotos. 



Dasyprocta punctata Gray. 



One specimen from Rio Lagotos. 



Lepus sylviaticus aztecus Allen. 



Five males from San Felipe of this strongly marked race. 



Urocyon cinereo-argentatus fraterculus, sub. sp. nov. 



San Felipe, Yucatan. 



A, lull Male. Top of head silvery-gray with very little rufous 

 perceptible, the hair being black at base, tipped with grayish-white. 

 Center of head darkest from nose to behind the ears, the black dom- 

 inating the gray. A superciliary grayish-white stripe from base of 

 nose to back of eyes. Back of head and neck gray with the fulvous 

 under fur showing, and giving to this part a wash of that color.

 root of tail almost entirely black, merely sprinkled with gray. Nose 

 black; base of ears behind dark fulvous, almost chestnut, rest of ears 

 to tips brownish-gray. Sides of neck and band across chest pale
