Crown of the head distinctly elevated above the short and obtuse 

 muzzle. Nostrils opening on the upper surface at the extremity of 

 the muzzle, in front of a naked space, bounded laterally by the 

 raised edges of the very prominent sides of the face ; anteriorly the 

 upper Hp is divided on each side by a deep groove passing down 

 from the nostril, and the intervening space between and below the 

 nostrils is prominent and rounded (Plate XI. fig. 10). Inner 

 margins of the ears uniting on the forehead slightly in front 

 of the eyes ; the outer margin is also carried forwards in front of the 

 eyes, temunating on the face above the upper lip, so that the eye is 

 contained within the external ear ; tragus triangular above and 

 attenuated towards the tip. Feet slender, with long toes. TaU 

 nearly as long or longer than the body. Skull considerably vaulted 

 behind the short muzzle.

* Although this genus was defined by Dr. J. E. Gray under the name Barba- 

 stellus before the term Synotus was used by Keyserling and Blasius, yet I agree 

 with Prof. Peters that the latter name should be retained, because the former 

 had been used many years previously to denote a genus very different from 

 Synotus. In 1831 the genus Barbastellus was defined, having for its type 

 Barbastellus pacificus. Gray. In 1838, or perhaps earlier, Dr. Gray discovered 

 that B. pacificus was a synonym ot Nyctophilus geoffroyi, Leach (1822), and, in 

 his " Bevision of the Genera of Bats," published in the Mag. Zool. & Bot. 1838, 

 he transferred the term Barbastellus to another genus, which he then defined, 

 and named as its type Vespertilio barbastellus, Sohreb. But the name Barba- 

 stellus having once been applied to denote a certain genus, cannot be transferred 

 from that genus to another (although the genus in question has been previously 

 defined and named), but must remain as a synonym.
