the Tres Marias Islands from the ordinary C. fiavirostris of the mainland of Mexico. 

 The peculiarity in colour claimed for the insular form is not apparent when a large 

 series of the true C. flavirostris is compared with birds from the Tres Marias ; but the 

 latter haTe a slightly broader white margin to the greater wing-coverts, which renders 

 them worthy of recognition. C. madrensis is said to be common on Maria Madre 

 and Maria Magdalena, ranging to the summits of these islands, and is probably found 

 on Maria Cleofa also. On Maiia Madre these handsome birds were most numerous 

 along the wooded sides of a canon at some distance from the coast. Early in the 

 morning they might be found among the smaller trees at the base of the foot-hills 

 near the settlement, but later in the day they retired further inland to the more heavily 

 forested slopes, perching on the higher branches of the trees, or flying about in twos or 

 threes. At Maria Magdalena numbers were observed in some trees near a group of 

 deserted houses and in old clearings a short distance from the shore, coming there to 

 feed upon the ripening fruit, but if startled they would take wing, making a loud 

 flapping noise that alarmed their companions, and then all dashed swiftly away. Wild 

 figs and the small fruit of a tree, probably a species of Psidium, or wild guava, were 

 favourite articles of food. Their loud cooing note is uttered at short intervals and is 

 one of the characteristic sounds in the forests they frequent. The species is essentially 

 arboreal in its habits and is rarely seen near the ground.
