Genus Avtiheus from Trinidad. 409 



Museum is indebted for many additions to its collection of 

 Trinidad animals. 



Artiheus Hartii^ sp. n. 



Size rather smaller than in A. bilobatus. Colour, so far as 

 can be made out in a spirit-specimen, dull brownish grey, the 

 bases of the hairs decidedly lig-hter than the tips ; upper and 

 under surfaces of apparently just the same shade ; no white 

 markings on face or back. Nose-leaf very short and broad, 

 the breadth of the upright portion almost equal to its iieight ; 

 horizontal portion entirely bound down to and continuous 

 with the muzzle in front, on the sides notched in the position 

 of the extra lobes in bilobatus, but without the lobes them- 

 selves. Ear short, rounded, the notch behind the antitragus 

 scarcely perceptible, but a marked emargination in the outer 

 edge of the ear just above the tip of the tragus. 



Skull, when viewed from the side, lower in the muzzle and 

 more abruptly elevated above the orbits than in A. bilobatus. 



Dental formula as in A. planirostris and bilobatus, i. e. 

 I. ^, C. Y, P. 2, M. 3 X 2 = 32, this formula characterizing the 

 subgenus Uroderma of Peters. Median upper incisors broad, 

 pointed in the centre of their cutting-edge. Canines short 

 and stout, their tips not projecting downwards beyond those 

 of the posterior premolars. Shapes and proportions of molars 

 very much as in A. bilobatus, except that the postero-internal 

 angle of ^^ projects inwardly some way beyond the inner 

 edge of ^1^, while the two are about level in that species. 

 Lower teeth also as in ^. bilobatus, except that the posterior 

 premolar is as short horizontally as the anterior, and is there- 

 foi-e decidedly shorter than nTI. 



Dimensions of the type (a slightly immature * male in 

 spirit) : — 



Head and body 52 millim. ; nose-leaf, height of lancet 5*5, 

 breadth of lancet 4*2, breadth of horseshoe 5'5 ; height of 

 ear 12*5; forearm 38; third metacarpal 35; tibia 13*6; 

 foot 9-5. 



Skull : basal length 16*8 ; distance from front of canine to 

 back of ?L^ 7-0 ; breadth of palate outside "^iii 8-2 ; vertical 

 length of upper canine 2"9. 



This species is only the third known member f of the sub- 



* The epiphyses of the limb-bones are not fully ossified, but the teeth 

 are all up and in use. 



t According to Dobson's Catalogue; but I strongly suspect thai 

 Peters's A. concolor, considered in that work as a mere variety of A. plani- 

 ro.striK, ought properly to be reckoned as a distinct species, equally dis- 

 arm. & Mag. N. Hist. Ser. 6. Vol. x. 28
