 Smith to resemble that of the Guinea Fowl.

This is one of the most interesting species of the group, and 

 it can be easily understood that the two sexes being so different 

 in plumage, they were at first described under different names. 

 It has now, however, been conclusively proved that they are 

 the male and female of one and the same bird (see Hunter, 

 /. s. c), yet, notwithstanding this, we observe, with some as- 

 tonishment, that in Dr. Reichenow's latest work on the Birds 

 of East Africa, the sexes are still regarded as distinct species ! 

 If any further evidence were required, we need only refer 

 to the parallel case of different sexes, found in the next species,
