Found them under stones near the road. When taken they 

 make a slight squeaking noise Hke a large beetle. Oct. 18. 

 Got quite a number of geckos on an old road that branches off 

 from the main one at about six hundred feet elevation. Jan. 

 25, 1906. Geckos have eggs in them now. Have not had the 

 good fortune to run across the Gonatodes as yet. I find the 

 other two kinds rare. Found no geckos shedding skins, as at 

 the time of our former visit. Jan. 27. Found a few geckos 

 at about 600 feet, all under the bark of trees. Feb. 23. Col- 

 lected three geckos. July 5. Today I hunted principally for 

 geckos, which I found scarce. July 7. Collected geckos and 

 again found them rare. Most were taken under bark of dead 

 trees, very few under rocks now. Went ashore in the evening 

 with Williams to collect insects with a light, and secured several 

 geckos on the edge of the beach. They probably were hunting 

 for the little flies and insects which were abundant. They 

 have the color of the sand, seem to be very much lighter than 

 in the daytime, and are, as usual, very active." 



General remarks. — Although this lizard has no enlarged 

 tubercles, it evidently is closely related to the geckos of the 

 other islands of the archipelago. The complete absence of 

 enlarged dorsal tubercles makes P. leei appear very different 

 from such forms as P. hauri and P. galapagoensis, but P. har- 

 ringtonensis shows an intermediate stage. The snout is longer 

 in P. leei than in P. harringtonensis. 



The eggs are elliptical in outline, white, with very thin, limy 

 shells. Their surface is covered with minute granules of lime 

 in straight rows which, when magnified, make the shell appear 

 covered with parallel scratches. One, taken in July, measures 

 9.4X6.5 mm. Others, found under lava blocks October 16-18, 

 1905, are 9.X6.8, 9X6.6, 9.2X6.1 and 9.X6.6. An embryo 

 taken from one of the October eggs measures 15.2 from snout 

 to anus.
