NO. 5 MAMMALS OF PANAMA — GOLDMAN 6j 



fenestratus Peters which was based on an old and a young example 

 from Costa Rica received through Drs. Hoffmann and Von 

 Frantzius. D. n. fenestratus seems to be intermediate in cranial 

 characters as well as geographic position between D. n. mexicanus 

 and typical D. n. novemcinctus. The skull differs from that of 

 D. n. mexicanus and approaches that of D. n. novemcinctus in the 

 depressed frontal outline, the shorter antorbital foramen, and in the 

 union of the jugal and squamosal near the postorbital process of the 

 zygoma. On the other hand it is nearer D. n. mexicanus and departs 

 from the typical form in the tendency toward anterior shortening of 

 the palatines between the last molars, and the laterally swollen con- 

 dition of the maxillae in front of the lachrymals. Dr. Glover M. 

 Allen 1 has pointed out characters distinguishing the Middle Ameri- 

 can animal from the typical form, but would unite D. n. fenestratus 

 and D. n. mexicanus under the former name. 



D. 11. fenestratus doubtless ranges throughout Panama, and is 

 probably a rather common animal, but owing to nocturnal habits is 

 seldom seen. Specimens have been taken in the western part of the 

 republic. Under the name Tatu novemcinctus three specimens col- 

 lected by J. H. Batty at Boqueron are listed and their measurements 

 given by Allen (1904, p. 60). 



Specimens examined : Gatun, 1 ; Boqueron, 3. 2 



Subfamily CABASSOUINAE. Five-toed Armadillos 



The armadillos of the subfamily Cabassouinae, unlike those of the 

 subfamily Dasypodinae, are provided with five toes on the fore feet. 

 The head is broad, the ears widely separated and the snout short and 

 broad ; the tail is shorter than the body and covered with skin. 



Genus CABASSOUS McMurtrie. Five-toed Armadillos 



Some of the more important characters of this genus have been 

 given in remarks on the subfamily. The skull differs widely from 

 that of Dasypus in general contour as well as in detail. It is short 

 and broad, with a short, stout and rapidly tapering rostrum ; the 

 jugal is broadest posteriorly, the outer surface flat ; the upper tooth 

 series extends posteriorly well beyond the anterior plane of the 

 orbital fossae ; the coronoid process of the mandible is very short and 

 exceeded in height by the condyle.
