224 DR. KNUD ANDERSEN ON BATS. [Apr, 7, 



in Artiheus nor in JJroderma is there any trace of a similar 

 projection. 



The material is unsuitable for a description of the wing- 

 structure, the only specimen known being a j^oung adult. It 

 would seem, however, that the wing-indices do not differ very 

 essentially from those of Artibetos; the second phalanx of the 

 third digit is, apparently, relatively leather short, less than 1 ^ the 

 length of the first phalanx. 



Species.^The type of the genus is the only species known. 



Range. — Trinidad. 



Enchisthenes harti Thos. 



892. Artibeus harti Thomas, Ann. & Mag. N. H. (6) x. pp. 409-10 (Nov. 1892). 



Diagnosis. — Upper tooth-row 8 mm. ; forearm 38 mm. 



Nose-leaves. — Horseshoe in front completely fastened down to 

 and continuous with the integument of the muzzle ; lateral part 

 turned up into a slight fold, somewhat recalling the fold in a 

 Uroderma horseshoe, but not forming a small rounded lobe. 

 Lancet unusually short and broad, the width at base being almost 

 equal to f its length from nostrils to tip. 



Interfemoral. — Extremely short, only about 3-4 mm. in the 

 middle line. 



Fur on limbs and interfemoral. — Upper side of proximal two 

 thirds of forearm, the whole of the interfemoral, and upper side of 

 tibia and foot, densely haired. A tuft of very short hairs on the 

 metacarpal of the pollex. 



Colour (of an immature specimen, preserved in alcohol). — The 

 colour of the fur would seem to be much as in the light phase of 

 Artibeus toltecus ravus (below p. 300). Details as to the facial 

 stripes and ear-margins cannot be given from the only specimen 

 available, which is not in a perfect state of preservation. 



Measurements. — On p. 223. 



Specimens examined. — One, the type, a young adult male, in 

 the collection of the British Museum. 



Range. — As yet only one record, from the island of Trinidad, 

 W.I.
