Charles, Chatham, Indefatigable and James. These were par- 

 tially reported on by Peters. 1 



In 1868 Dr. Habel made a collection of reptiles on Abingdon, 

 Bindloe, Hood and Indefatigable. These were reported on by 

 Steindachner 2 who also received most of the reptiles taken by 

 the Hassler expedition in 1872 on Albemarle, Charles, Inde- 

 fatigable, James and Jervis. 



Commander Cookson of the Petrel, in 1875, collected some 

 reptiles, chiefly tortoises, at Abingdon, Albemarle and Charles ; 

 these have been reported on by Giinther. 3 



The Albatross, in 1888, made quite extensive collections on 

 Albemarle, Charles, Chatham, Duncan and Indefatigable. 

 These were reported on by Cope. 4 



Dr. Baur, in 1891, made a very extensive collection of reptiles 

 in the archipelago. His specimens are from Albemarle, Abing- 

 don, Bindloe, Barrington, Charles, Chatham, Duncan, Hood, 

 Indefatigable, James, Jervis and Tower. This collection has 

 been reported on by Baur 5 and Garman. 6 



Re-ptilian Derivation. Eight genera of repiles occur in the 

 Galapagos Archipelago, two of which are peculiar and obvi- 

 ously of American derivation, being represented by allied gen- 

 era on the adjacent continental coast. All the genera not pecu- 

 liar to the archipelago, except Testtido, are found on the western 

 slope of the Andes. The distribution of the eight genera of 

 Galapagos reptiles is as follows : 



Chelone. Tropicopolitan. 



Gonatodes. Tropicopolitan. 



Phyllodactylus. Tropicopolitan. 



Tropidurus. Neotropical. 



Amblyrhynchus. Peculiar. 



Conolofihus. Peculiar. 



Dromicus. West Indian and Neotropical. 



Testudo. Nearly cosmopolitan ; lacking in South 



America west of the Andes.
