Phyllodactylus galapagoensis duncanensis, new subspecies. 

 Duncan Island Gecko. 



Diagnosis. — Limbs without enlarged tubercles; back with 

 distinct rows of enlarged tubercles, six on each side ; no median 

 series of broad subcaudals; large dorsal tubercles set close 

 together except in the upper dorsal rows, where they are usu- 

 ally separated by two or more granules; tubercles of some 

 dorsal rows continued on neck anterior to insertion of fore- 

 limbs ; snout shorter than in P. g. daphnensis; many enlarged 

 tubercles on top of head. 



Type. — California Academy of Sciences No. 10600. Dun- 

 can Island, Galapagos Archipelago. J. R. Slevin. Dec. 9, 

 1905. 



Material. — Only two specimens are in the Academy's collec- 

 tion. 



Description and Variation. — See P. galapagoensis. 



Habits. — Nothing is known of the habits of the geckos of 

 Duncan Island. Mr. Slevin's field notes contain only the fol- 

 lowing item: "Dec. 11 to 16, 1905, I got three geckos near 

 the camp, but they were rare and I did not have much time to 

 look for them."
