numbers. It was collected in only three localities : at an eleva- 

 tion of 1400 feet in the foothills of the Sierra Laguna Moun- 

 tains, at San Antonio 803 feet above sea level, and at San 

 Pedro. While collecting with a light early in the evening 

 forty-six specimens were taken around the public square in 

 the little village of San Antonio. They were heard calling 

 late into the evening. A specimen captured was observed to 

 make a shrill whistling noise of four or five seconds duration 

 with about the same interval, the throat swelling considerably 

 while it was doing so. The stomach of a specimen picked up 

 dead contained the wing covers of several species of small 

 beetles. 



At Ensenada, in Julv, 1905, a number of young specimens 

 (Nos. 8562-8569, 8576-8578, 8580-8589, 8645-8672) were 

 secured. 



6. Hyla regilla Baird & Girard 



During the visit to the Cape Region, only one locality was 

 found where this little tree-toad might be expected to occur. 

 This was in the Sierra Laguna opposite Todos Santos, at an 

 elevation of 5400 feet. The only two specimens (Nos. 47255, 

 47256) taken were found in the wet grass alongside a stream of 

 running water. During the night a few were heard calling, but 

 a thorough search of the streams and much beating of grass 

 resulted in no more specimens being found. 



At Ensenada, eight typical specimens (Nos. 8570-8573, 

 8590-8593) were collected in July, 1905. 



7. Hyla arenicolor Cope 



On February 27, 1908, Mr. R. H. Beck collected twenty 

 specimens (Nos. 13424-13443) of this tree-toad at Ensenada. 

 These seem to furnish the first definite record of this species 

 in Lower California. Mr. Beck did not secure any specimens 

 of Hyla regilla, which was the only species found by the 

 Academy's collectors at Ensenada in July, 1905. 



9. Phyllodactylus tuberculosus Wiegmann 



A single gecko of this species (No. 3829) was found by 

 Dr. Eisen at San Xavier.
