DESCRIPTION OF A NEW GECKO FROM BOTEL TOBAGO 

 ISLAND. 



By Masamitsu Oshima. 

 (Of the Institute of Science, Government of Formosa.) 



In June, 1912, I collected a pair of geckos at Kotosho (Botel 

 Tobago Island, dependency of Formosa) that appear to represent 

 an undescribed species. I take great pleasure in dedicating it 

 to my collector, Yonetaro Kikuchi. 



Gecko kikuchii sp. nov. 



Habitat. — Kotosho, Formosa. 



Type. — Catalogue No. 1; Institute of Science, Government of 

 Formosa; Kotosho (Botel Tobago Island); June 14, 1911; 

 M. Oshima, collector. 



Description of type. — Rostral pentagonal, about twice as wide 

 as high, bounded above by 2 large internasals and 1 small scale 

 between the latter, the supralateral margin entering the nostrils ; 

 nostril between first supralabial, rostral, large internasal, and 2 

 larger shields above and behind; distance between nostril and 

 eye considerably greater than the distance between eye and

 tance between eye and tip of snout; ear-opening large and oval, 

 its longest diameter one-half the diameter of eye; 13 supra-

 10 lower labials; behind mental a pair of median, somewhat 

 elongated chin-shields, on either postero-lateral side of which

 on the snout considerably the largest ; among the granules, from 

 the ear-opening backward to the basal half of the tail, numerous
