on the upper part of the nose, one-third nearer the tip of the snout 

 than the orbit, swollen, and pierced between two larger raised posterior 

 and two smaller anterior nasals. Forehead and the interorbital space 

 with a longitudinal groove. Temporal region thick and swollen; the 

 greatest breadth of the animal is at the temples. Body and limbs 

 slender. On the band the free distal joints are comparatively long, on 

 the 3 th finger as long as the diameter of the ear-opening : a low ridge 

 limits the palmar surface behind, giving it a scooplike appearance. On 

 the foot the free distal joints are considerably shorter; the outer toe, 

 to some extent separated from the broad diso, formed by the four other 

 toes, makes the bind rim of the deeply coneave palmar surface. A broad 

 but low rostral in contact with a regulär six-sided internasal: 14 — 16 

 upper labials, 12 lower labials; a large oval mental, no chin-childs ; 

 all other scales small and granulated, except a row of-ten pointed conical 

 tubercles on each side the thick base of the tail, probably a male- 

 character. Greyish white above, head and tail lighter than body : two 

 faint dark stripes on the sides of the back, vanishing on the base of 

 the tail ; several faint cross bands unite the longitudinal stripes : above 

 the ear a dark transversal spot, and on the nose a semicircular streak 

 running bebind the nostrils to below the eyes ; the lower parts of the 

 sides between the limbs, a triangulär patch in front of the Shoulder, 

 the angle between thighs and tail, and the eyelid citrine; lower parts 

 white, greyish white on the head. 



Measurements: Total length 110 mm: from nose to ear 17,5mm; 

 diameter of the orbit 6 mm, greatest breadth of head 14 mm. length 

 of humurus 9 mm, from elhow to the tips of toes 17 mm, length of femur 

 12 mm, from knee to tips of toes 20 mm. 



This singular gecko is from Lüderitzbucht in the German South- 

 West Africa and collected by Dr. P. Range: the colour, the large 

 palmar surfaces and the general appearance indicate its oecurrence in 

 arid regions; in habit it rather mach resembles another sand-gecko 

 from South-Africa, Pteno})iis garrulus, also collected at the same 

 place, to which it probably is related, bu f , the large palmar surfaces, 

 formed as broad adhesive Organs, seem to indicate that its habits at 

 least to some extent are different: perhaps it may be iiving on rocks, 

 but without knowing the nature of the place where it is collected, 

 I do not find it proper to go further into the matter.
