CEDROS ISLAND PJ.ANTS. 



Dr. Palmor spent three days on tlie noitli end of this island, iMarch 

 18 to 20, and made a large and valuable collection. Ilis numbers i-un 

 from G77 to 704, and unfortunately are partly dnplicatetl in the ISan 

 Quentin collection of the same year. 



Mr. Gireene has published (IMttonia, vol. 1, 200-208) a list of the 

 known si)ecies of this island, and also a supplement [1. c. 2G0-2G0) list- 

 ing ninety-one species. l)r. Talmer has added at this time forty-three 

 species to the tlora of the island. Dr. Streets, who visited this island in 

 1870, and inade a small colk'ction, found here AbutUoti Lemmom, which 

 has not been since rediscovered. Mr. LJelding has also collected here, 

 but not very extensively. The species now known to the island are 

 one hundred and thirty-five.
