neio Mammals from Chiriijui. 381 



might be accepted by tliose who think this group should be 

 genericallj separated from true Bassariscus. 



Coendou Icenatus, sp. n. 



Allied to C. mexlcanus, but smaller, more heavily clothed, 

 and with less inflated skuH. 



General external appearance as in G. mexicanus and 

 C. m. 7/ucatanice ; the woolly coat very thick, soft, and long, 

 and more entirely hiding the spines than usual, the spines 

 only showing through the fur on the head, and very incon- 

 spicuously along the sides, not on the tail or limbs. Colour 

 of fur blackish brown throughout. 



Spines of back attaining to about 38-40 millim. in length, 

 their basal three fifths pale yellowish white, less yellow than 

 in the allied forms, their ends brownish black with a slightly 

 paler horny tip. Spines of head shorter, only attaining about 

 30 millim. in length, still whiter, their basal fourth only 

 tinged with yellow, and witli their dark end only about one 

 sixth of their length. Under surfjice blackish, the spines as 

 usual bristly and black-ended. Hands, feet, and tail wholly 

 black. 



Skull entirely different from that of C. mexicanus. Much 

 smaller, flatter, and not inflated in the frontal region. 

 Muzzle not abnormally thrown forward, the anterior part of 

 the premaxilla projecting but little in front of the nasals, so 

 that the plane of the nasal opening is almost vertical. Nasals 

 broad in front, strongly and evenly narrowing backwards — • 

 in mexicanus they are parallel-sided, or even narrow for- 

 wards. Supraorbital edges square posteriorly, with well- 

 defined ridges. Palatal foramina ending just at the pre- 

 maxillo-maxillary suture. Hinder edge of palate level with 

 the back of m^. Bullae rather smaller than in C. mexicanus. 



Dimensions of the type (measured in the flesh) : — 



Head and body 452 millim. ; tail 256 ; hind foot, s. u. 65, 

 c. u. 75. 



Skull : greatest length 80 ; basilar length 67 ; zygomatic 

 breadth 47 ; nasals — length 24^ breadth anteriorly 16, breadth 

 at fronto-premaxillary suture 12'8; interorbital breadth 25'5; 

 height of forehead at back of nasals from palate between 

 premolars 27*7; diastema 21 ; length of palate 35'7; length 

 of upper tooth-series 19. 



Ilab. Boquete, 5000 feet.
