A NEW GECKOID LIZARD FROM THE PHILIPPINE 



ISLANDS. 



By Leonhard Stejneger, 



Curator, Division of Reptiles and Batrachians, U. S. National Museum. 



During a visit to some of the islands north of Luzon, composing 

 the Babuyan group, Mr. R. C. McGregor, of the Science Bureau, 

 Manila, collected on the islands of Fuga and Calayan a series of 

 lizards which he kindly donated to the United States National 

 Museum." As might be expected, they belong to the families 

 Gekkonidse and Scincidse, the latter being represented by numer- 

 ous specimens of Mahuya multicarinata, Dasia smaragdin^, and 

 SpTienomorpTius jagorii from both islands, besides a single Emoia 

 atrocostata from Fuga. Of the geckos the collection contains Hemi- 

 dactylus frenatus from both islands, Ge'klco monarchus from Calayan, 

 and an undescribed species from the latter island. This new species 

 evidently belongs to the genus Luperosaurus, and I take great pleas- 

 ure in dedicating it to its discoverer, who has contributed so much to 

 our knowledge of Philippine zoology.

 very slight ones along the legs; tail not keeled laterally, nor flattened 

 underneath.
