Tloo neio Species of Bats. 575 



on ScotopMlus Schlieffeni and other mammals from Aden 

 formed the first contribution to the mammalogy of that 



rropteniis Tomesi, sp. n. 



A large species allied to.//. TichelU, but wholly dark brown, 

 like a Noctule. 



Size about as in H. TickeUi^ the skull rather larger but the 

 wing-bones shorter. Fur close and fine, the hairs of the 

 back about 4-5 ram. in length, but those of the nape much 

 longer, attaining 8-10 mm. Base of intcrfemoral sliglitly 

 haired above and below, rest of the membranes naked. 

 General colour above uniform dark brown (" burnt umber," 

 but darker), the hairs darkest at tlieir bases, rather lighter 

 mesially, and witli dark tips, but tiie difference is scarcely 

 perceptible. Under surface similarly uniform brown (about 

 matching llidgway^s burnt umber) throughout. Wing- 

 membranes everywhere dark brown. 



Ears short, rounded above, with a small rounded basal 

 lobule at the base of their inner margin ; outer margin ending 

 in a long low antitragal lobule. Tragus very broad, its 

 inner margin faintly concave, tip pointed ; outer margin 

 very convex, strongly bowed opposite the base of the inner 

 margin ; outer basal lobule rounded ; a narrow band of fine 

 hair passing across the front face of the tragus at its broadest 

 point. Wings to the end of the metatarsus. Postcalcareal 

 lobule narrow. Penis long, with a very long bone, similarly 

 Y-shaped to that of H. Tickelli, but twice as long (10 mm. 

 in length in the type) and much thicker ; whether the glands 

 and prepuce are similar to those of //. Tickelli cannot be 

 determined on the dried type. 



Skull rather larger than that of //. Tichelli, the sagittal 

 crest rather lower, but the posterior " helmet ^' more projected 

 backward. 



Teeth larger and heavier than those of //. Tickelli. P 

 large in section, its postero-external side almost touching the 

 canine outside i^, which is also very large, placed quite 

 behind i^, opposite the middle of the canine, and is separated 

 from the inner corner of the premolar by a distance only equal 

 to its own diameter. Premolar much extended transverselj^ 

 Below, the incisors are all heavier than in H. Tickelli, t\ being 

 particularly large. 



Dimensions of the type (measured in skin) : — 



Forearm 51 mm. 



Head and body 74 ; tail (vertebrae in place) 44 ; ear 14 ;
