90 The Philippine Journal of Science 1915 



Everett,- Boulenger,^* Griffin,* and others, has more species of 

 reptiles in common with Borneo than have the other islands. 

 The large number of species known only from Mindanao suggests 

 that this island has a reptilian fauna peculiar to itself. How- 

 ever, the knowledge of the herpetological faunae of all the islands 

 is very incomplete. 



Fewer than 15 species and varieties of lizards have been 

 described from the Philippine Islands since the publication of 

 Boulenger's catalogue,^ thirty years ago. In the present paper 

 14 species are described as new. These are: 



Gymnodactylus agusanensis. Sphenomorphus mindanensis. 



Gymnodactylus annulatus. Sphenomorphus coxi. 



Hemidactylus luzonensis. Sphenomorphus curtirostris. 



Ptychozoon intermedia. Sphenomorphus palustris. 



Luperosaurus compresicorpus. Dasia griffini. 



Lepidodactylus aureolineatus. Tropidophorus rivularis. 



Emoia ruficauda. Dibamus argenteus. 



Dasia semicincta (Peters) has been redescribed in this paper 

 from a splendid series of specimens. It appears to be distinct 

 from D. olivacea Gray, and I doubt if the typical form of the 

 latter occurs in the Islands. The entire collection has not been 

 gone over, and further study will probably bring to light other 

 new species. 



Special thanks are due to Dr. Alvin J. Cox, director of the 

 Bureau of Science, and Dr. R. P. Cowles, of the University of 

 the Philippines, for facilitating this work; and to Mr. Artemus 

 L. Day and Mr. S. F. Light, of the University of the Philippines, 

 for checking identifications and assistance rendered in various 

 other ways. .

 arranged in whorls.
