ceeded by the posterior prolongations of these bones. In all the skulls 

 of the Cuban pilorides examined, the posterior dorsal border of the 

 parietal has a conspicuous medial emargination ; whereas that of relic- 

 tus is nearly straight across. Apparently, also, the slight postorbital 

 processes of the frontal seen in the Cuban skulls are much less 

 developed in the Isle of Pines race; so that the supraorbital margin is 

 much more nearly straight. Other slight differences, such as the 

 greater curvature of the ventral outline of the ramus, are less 

 tangible, or due, perhaps, to individual variation. 



Measurements. — No external measurements of the Isle of Pines 

 specimens were taken. The dry skins, which are carefully made, 

 show the following dimensions in millimeters: — 



The skull of the type. lacks the condylar region. Its dimensions 

 follow; and for comparison the corresponding measurements of 

 a Cuban C. pilorides, No. 7231, are added in parentheses: — greatest 

 length, 94.5 (111); palatal length, 42 (53); diastema, 25 (32); zygo- 

 matic breadth, 49 (52); interorbital constriction, 27 (29); nasals 

 (median length), 25 (36.5); upper cheek teeth (alveoli), 20 (23); 

 lower cheek teeth (alveoli), 20.5 (23); ramus from condyle to tip of 

 incisors, 63.5 (76).

Poeppig considered this species to be rarer than C. pilorides. He 

 had specimens from the mountains of southern Cuba — Partido de 

 las Piedras, Maeurizes, Masmariges. Mr. Chapman records speci- 

 mens from western Cuba, at San Diego de los Bafios and Cabanas. 

 No doubt this and the short-tailed hutia were once generally dis- 

 tributed throughout the island. Its local names are " Hutia caraballi " 

 or "Hutia mono."
