Similar in coloration to C. cagottis (Ham. Smith) , but much larger, 

 and the upper carnassial with a prominent protocone; in size and 

 dental characters similar to C. mearnsi, but much paler, the throat and 

 ventral region only slightly suffused with pale fulvous instead of buffy 

 ochraceous, and fore and hind legs and feet not "bright orange fulvous 

 all around," but fore legs posteriorly and hind legs and feet anteriorly 

 pale fulvous, or pale yellowish white, as in cagottis. 



Measurements. Type, total length, 1143; head and body, 838; 

 tail vertebras, 305; hind foot (in dry skin), 178. Skull, total length, 

 190; basilar length of Hensel, 163; palatal length, 89; zygomatic 

 breadth, 93 ; mastoid breadth, 59 ; length of crown of upper carnassial, 



19-3- 



The collector's external measurements of 7 adults are as follows: 



3 males, total length, 1189 (1130, 1143, 1295); head and body, 855 

 (800, 838, 927); tail vertebras, 334 (330, 305, 368); hind foot, 178 

 (given for one specimen only); ear from crown, 152 (i specimen): 



4 females, total length, 1123 (1105-1181); head and body, 806 (787- 

 826); tail vertebras, 341 (305-368); hind foot (not given) ; ear from 

 crown, 138 (127-146). 



Skull measurements of 4 males and 4 females: 4 males, total length, 

 195.6 (190-202); basilar length of Hensel, 170 (163-173); palatal 

 length, 91.6 (89-93); zygomatic breadth, 93.5 (93-94; 2, the two 

 largest being imperfect); mastoid breadth, 60.7 (59-62); length of 

 crown of upper carnassial tooth, 19.7 (18.6-20.5): 4 females, total 

 length, 190.5 (189-193); basilar length of Hensel, 166.3 ( J 64. 3-169); 

 palatal length, 91.5 (90-94); zygomatic breadth, 95 (92-97); mastoid 

 breadth, 59.4 (58-60.5); length of crown of upper carnassial, 18.3 

 (17.3-19.5). Six of the specimens are middle-aged adults; the other 

 two (a male and female) are old adults with greatly worn teeth. In 

 each case these two specimens are, respectively, the largest of the two 

 series. 1 



The young specimens (so young that the eyelids remain tightly 

 closed in the skins, even after the process of skinning) have the front 

 of the head as far back as the eyes, including sides of nose and chin, 

 blackish brown; the rest of the head and body dark buffy brown, 

 nearly black along the median line of the back, lighter on the sides of 

 the body and beneath, with a large white pectoral area, varying in 

 size, shape, and in the purity of the white in different individuals; 

 limbs and tail blackish, like the nose. 



r The old male skull is especially interesting pathologically, on account of an accident, 

 received apparently in early life, to the right side of the skull, resulting in a fracture of 

 the zygomatic arch and serious injury to the right ramus. The broken parts of the arch 

 became displaced and failed to unite, resulting in their partial atrophy and a marked 

 asymmetry of the skull, including an axial curvature to the left. The axis of the right 

 ramus is also curved inward instead of outward, and, with the loss of the last two pre- 

 molars, has undergone more or less atrophy. Yet the specimen, in both external and 

 cranial measurements, is the largest of the series. Externally the head shows no sign 

 of injury.
