The only specimen of this bird contained in the Society's col- 

 lection was injured before it came into the hands of Mr. Caley. 

 It is however sufficiently preserved to show the genus to which 

 it belongs, and to afford a clear specific distinction. The bill 

 has all the characters of that of the true Caprimulgus, being 

 weak, narrowed, and much compressed at the apex, with round 

 and elevated nostrils : the legs also, like those of the same genus, 

 are short, weak, and feathered to the toes, which are uneven, 

 and have the middle nail serrated. The wings are more rounded 

 than in other Goat-suckers ; but this apparent deviation from 

 the genus is probably owing to the mode in which the specimen 

 has been prepared. The plumage above is nearly perfect ; and 

 the wings exhibit without any deficiency the beautiful series of 

 regular round spots described above, from which the specific 

 name has been derived. But the plumage of the abdomen, and 

 of the under-parts generally, is defective. Mr. Caley informs 

 us that the bird was picked up dead on his premises in its pre-
