of the ‘‘Peterel’’ in 1875. Concerning the ants taken by the 
“Albatross” expedition of 1888, Howard*® in 1890, makes 
only the following statement: ‘dark-colored species of the 
genus Camponotus was collected, one male from Albemarle 
Island, numerous males and two females from Charles Island. 
Of a light-colored species of the same genus seven males 
were taken on Charles Island and one on Albemarle Island.” 
These were, without doubt, the sexual forms of Smith’s C. 
planus and macilentus. In 1893 Emery* recorded the follow- 
ing species which he had received from Dr. George Baur, 
who made an expedition to the islands in 1891 in a sloop 
chartered in Guyaquil: Solenopsis geminata Fabr., Tet- 
ramorium guineénse Fabr., Tapinoma melanocephalum Fabr., 
Odontomachus bauri Emery, and Camponotus peregrinus 
Emery. All these forms were taken at Chatham Island, 
and all, except the first, were found on the ship, so 
that two of them, Tetramorium guineénse and Tapinoma 
melanocephalum, may have had their nests in the woodwork 
and may have come from Guyaquil. The Camponotus pere- 
grinus can hardly be more than a variety of Smith’s planus. 
Emery also mentions the receipt of five males of the genus 
Camponotus taken on one of the “Albatross” voyages: “One 
of them is black and comes from Albemarle and Charles 
islands, the other, of a testaceous color, with very pale legs, 
is represented by two specitnens from Charles.’ These seem 
to be part of the two series mentioned by Howard, i. e, 
specimens of C. planus and macilentus. Since the publica- 
tion of Emery’s paper no additions have been made to the 
seven or eight forms recorded from the archipelago. I was 
much interested, therefore, to learn from Dr. F. X. Williams, 
that he had collected a number of ants while he was a member 
of the California Academy of Sciences Expedition (Voyage 
of the “Academy’’?) in 1905 to 1906. Through the kindness 
of Dr. E. C. Van Dyke the specimens were loaned me for 
study. Dr. Williams also informed me that some ants had 
been taken by the Hopkins-Stanford Expedition to the Gal- 
apagos (Voyage of the “Julia E. Whalen’) in 1898 to 1899,
