262 Mr. A. W. E. O'Shaughnessy on 



Genus Vesperugo. 



Vesperugo, Keys. & Bias. Wiegm. Arcliiv, 1839, p. 312. 

 Vesperugo ( Vesperus) platyrhinus, n. sp. 



Muzzle broad and obtuse ; glandular prominences large, 

 smoothly rounded ; nostrils opening near the margin of the 

 upper lip, on a level with the rounded extremity of the muzzle, 

 not emarginate between. The front of the muzzle is evenly 

 bevelled off from the summit of the glandular elevations to 

 the margin of the upper lip ; and the nasal apertures are 

 narrow, appearing as small oblique slits in the front of the 

 muzzle. Ears and tragus as in V. Kuhlii. 



Wings from the base of the toes ; postcalcaneal lobe small, 

 but distinct ; last caudal vertebra half free. 



Fur above dark brown, paler towards the tip ; beneath 

 similar, the extremities of a lighter colour than on the upper 

 surface. 



Upper inner incisors long, faintly bifid at the extremities ; 

 outer incisors very short, scarcely equalling the cingulum of 

 the inner ones ; lower incisors crowded, trifid ; no minute 

 upper premolar ; the single upper premolar very close to the 

 canine. 



Length (of an adult male) — head and body 1*8 inch, tail 1'4, 

 head 0'7, ear 0*55, tragus 0*25, forearm 1*35, second finger 

 2-15, fourth finger 1'65, tibia 0'45, foot 025. 



Hob. Unknown. Type in the collection of the British 

 Museum. 



This very peculiar species of Vesperugo resembles V. Kuhlii 

 in size and in general form ; but the absence of the first 

 minute upper premolar and the shape of the muzzle at once dis- 

 tinguish it. The shape of the muzzle is so peculiar as to lead 

 me to suspect it may be an individual peculiarity. As the 

 specimen from which the description is taken is well preserved 

 in alcohol, this flattening of the front of the muzzle and ex- 

 tremities of the nostrils is not due to imperfect preservation.

Phyllodactylus tuberculosus, 



described by Wiegmann (Acta Ac. Nat. Curios, xvii. p. 

 241, pi. 18. fig. 2) from California, to which we must add 

 as a synonym the Phyllodactylus Xanti described by Cope
