BIRDS OF THE GALAPAGOS ARCHIPELAGO— RIBGWAY. vol.xix. 



and it is not unlikely that when a series of specimens from each in cor- 

 res])Oiuling' plumage can be compared, a greater or less number of local 

 forms may be made out. 



I am not entirely sure that the bird here described is the true C 

 rarityatKS, not having been able to examine specimens from tlie alleged 

 type locality (Abingdon island). Regarding the latter question, it may 

 be stated that both j\Ir. Townsend, naturalist of the U. S. S. Albatross, 

 and Messrs. Baur and Adams failed to tind any other Camarhynclius 

 than C. haheJi and its near ally, C. bin(lloci,on either Abingdon or Bindloe 

 islands. Dr. Baur writes me as follows: 



Ilabol, according to Salvin. states that both species [C. haheli and C. rariefiatus'] 

 are found simultaneously on Hindloc and Abingdon. This is certainly not true. 



The question therefore arises : Where were the type and other speci- 

 mens of C. rayi€(/att(s, accredited to Abingdon and Bindloe islands, 

 respectively, really obtained ?
