animal of western and southern Hispaniola, and P. hylaeum 

 that of the northeastern parts of the island. Even so, the 

 ranges could hardly have been entirely separate, for in a later 

 paper, Miller (1930), reporting on mammal remains from 

 Indian kitchen middens on the valley floor near Constanza in 

 the mountainous interior of Dominican Republic, identifies 

 both species as present. Evidently both were used as food by 

 the aborigines. 



It is significant that this well-distinguished genus is as yet 

 unknown in either fossil or recent state from any other Antillean 

 islands or from the mainland. 



LEAST HISPANIOLAN HUTIA 

 PLAGIODONTIA SPELAETJM Miller 



Plagiodontia spelaeum Miller, Smithsonian Misc. Coll., vol. 81, no. 9, p. 18, Mar. 10, 

 1929 ("The crooked cave near the Atalaye plantation, Haiti"). 



Nothing is known of this supposed third species of Hispanio- 

 lan Plagiodontia beyond the account given by Miller, who 

 found 15 mandibles, four in the group of caves near St. Michel 

 in north-central Haiti, and the>others in the "crooked cave" 

 near the Atalaye plantation in the same region. Its main 

 point of difference from P. aedium, remains of which occurred 

 in the same caves, lies in its smaller size, as indicated by the 

 mandibular tooth row of 15.6-16.2 mm., as against 23.6 in the 

 former. Compared with P. hylaeum, the discrepancy is less, 

 for the latter has a tooth row of 18.6 mm.

Isolobodon portoricensis J. A. Allen, Ann. New York Acad. Sci., vol. 27, p. 19, 1916 



("Cueva de la Ceiba, near Utuado, Puerto Rico"). 

 FIGS.: Allen, J. A., 1916a, pis. 1-5; Anthony, H. E., 1918, pi. 62, figs. la-6b; pi. 63, 



figs, la-b, 4-12c; pi. 74, figs. 6a-c; text-fig. 39, A-H (skeletal parts). 



This well-marked genus is as yet unknown in the living 

 state and is undoubtedly extinct, although abundantly repre- 

 sented in kitchen middens of the Indians in Puerto Rico, 

 the Dominican Republic, and the Virgin Islands. 



The skeletal characters, which alone are available, show that 

 it was an animal of about the size of the Hispaniolan hutias, to 

 which it is somewhat closely related. Its teeth, however, are
