South-western Madagascar. A single male specimen, 

 collected by Mr. Last. 



Homopholis heterolepis. 



As the specific name chosen implies, this Gecko differs 

 from the type of the genus in the heterogeneous lepidosis of 

 the back. Its general agreement in other respects with 

 //. Wahlbergii, Smith, is so great that I would alter the 

 definition of Homopholis rather than establish a new genus, 

 a course which is, besides, in keeping with that followed 

 in other cases (e. g. Stenodactylus, Hemidactylus) . 



General proportions and digits exactly as in //. Wahl- 

 bergii; forehead concave ; ear-opening rather small, oval, 

 oblique. Snout covered with juxtaposed convex granules, 

 largest on the sides ; back of head finely granulate, with 

 small round tubercles ; rostral twice as broad as deep ; nostril 

 pierced between the rostral, the first labial, and four or five 

 scales; 11 upper and 9 lower labials; a row of chin-shields 

 in contact with the symphysial and the anterior lower labials, 

 the median pair rather large and longer than broad. Back 

 covered with small, juxtaposed, flat granules intermixed with 

 round or oval, smooth or feebly keeled tubercles, disposed 

 irregularly ; 16 tubercles in a transverse series in the middle 

 of the body. Limbs covered with small, juxtaposed, or sub- 

 imbricate smooth scales ; ventral scales small, imbricate, 

 smooth. Tail cylindrical, tapering, covered with small, 

 imbricate, smooth scales, above with transverse series of nail- 

 shaped, smooth, or feebly keeled flat tubercles, below with a 

 series of transverse shields. Greyish above, with rather 

 indistinct wavy cross-bars ; a dark streak from the eye to the 

 first cross-bar j white beneath.
