Thadmastura. As both 0. vesper and O. fanny became subscqiiently the types of 

 other genera, the 0. cora is lett to represent Thaumastuka, 13on., although it was 

 not originally intended as the type.

Female. Head gray-green. Upper parts bronzy-green. Under parts buffy-white.

 lateral ones white, with a broad subterminal black band. Total length, 3j in.

As now constituted, the next genus Doricha, comprises species of very different 

 forms so far as their tails are concerned. The one I have placed first, the D. 

 enicura, has similarly shaped rectrices to those of Thaumastura cora; the D. eliza; 

 has moderately long, broad tail feathers, while the remaining species have narrow 

 rectrices, all of which are about equal in length, while those of the first two men- 

 tioned are of diff"erent lengths. Although many genera of this Family have been 

 made on far less important dift'erencc than these, yet I believe it is the proper 

 course to keep them all in one genus, for in every other respect they are closely 

 related. They are all small birds, and the males have luminous throats.
