will be found to be the case. The relationship to the Mimincc seems to 

 be a very remote one, and even the external spotted appearance, which 

 appears to have been the chief reason for uniting it with those birds, 

 shows only a slight and very superficial resemblance to the genus Mar- 

 gar ops. 



This genus is peculiar to the lesser Antilles.

Size, moderate; prevalent color, bluish gray; the outer tail-feathers 

 having a large white patch at the tip. Wing somewhat rounded, the 

 third, fourth, fifth, and sixth primaries being longest; the third never 

 longer than the sixth and considerably shorter than the fifth ; second 

 primary shorter than the seventh, and never longer than two and three- 

 fourth times the first; secondaries rather long. Bill large and rather 

 slender; the commissure with a more or less distinct notch, only very 

 little larger than two times the gonys; chin-angle not protruding before 

 the nostrils. Eictal bristles inconspicuous. Tarsus somewhat length- 

 ened, but less than twice the exposed culmen. Tail graduated and long, 

 the outstretched legs falling far short of its tip ; the largest tail-feathers 

 about five times the tarsus and about as long as the wing. Below and 

 behind the eye a naked space. 



Remarks. — The few species composing this genus, which is confined 

 to the West Indian Islands, form a well circumscribed group. It shows 

 some relationship towards the Miminw, but as neither its position among 

 the TiircUdw nor its validity as a distinct genus has been disputed, it needs 

 no further remarks at this place.
