conte in TenerifFe, but was unable to obtain specimens, and did 

 not then distinguish it from C. turtur. Bolle seems uncertain to 

 which species it should be referred, Vernon Harcourt says the 

 last-mentioned species is found occasionally in Madeira.

It is found in the Canaries only in the wooded ravines near the 

 patches of cultivated land in the mountains, where sometimes

 they come to drink. I have very frequently seen them exposed 

 for sale in the market-place in Santa Cruz. It is said to be 

 wanting in Lanzarote and Fuerteventui'a.

Very common in all three archipelagoes, where they are
