I am much inclined to doubt whether this Motmot is really found 

 in the Bahamas. It is common in Tobago and Trinidad. It is easily 

 distinguishable from its affines by the deep uniform chestnut colour- 

 ing of the lower surface.

This fine large green northern representative of M. brasiliensis 

 may be recognized from its congeners by having the blue hind-border 

 to the cap edged with black towards the nape. This is also the case 

 in M. cequatorialis, but I have already mentioned its differences from 

 that species. 



8. Momotus cceruleiceps.

Lesson's M. subhutu, described in the little summary of this group 

 given in his ' Description des Mammiferes et Oiseaux,' is attached 

 by Prince Bonaparte to his M. psalurus with a mark of doubt. But 

 on attentively considering Lesson's description, I think there can be 

 little doubt this is the bird really intended by it.
