respect with South Brazilian examples. The wing measures 112, the tail 89i, the 

 bill 19i mm. From M. b. atronitens Cab. (ex Para, Guiana, Orinoco delta, etc.) it 

 differs bj' its much larger size and stronger as well as longer bill ; from 

 M. b. veiiezueleiisis Stone by its stouter bill and decidedly purple (not steel-blue) 

 coloration.

The types, an adult male and a young female, are still the only specimens known 

 of this well-marked form. I am greatly indebted to my friend Dr. von Lorenz, 

 of Vienna, for the loan of these valuable objects. Compared with a good series of 

 C. c. chrysops from Paraguay and Southern Brazil (S. Panlo), the adult bird differs in 

 many important particulars. The feathers of the pileiim are somewhat stiffer and 

 much more elongated, the longest measuring fnlly 20 mm., so as to form a very distinct, 

 erect crest; the wings are longer; the bill decidedly shorter; the yellowish white 

 apical portion of the reclrices conspicuously shorter. The blue spots on the sides of 

 the head are much more restricted ; the supra-ocular spot is much smaller and 

 uniform lilac-blue (not mixed with sky-blue), and in the malar region there is only 

 a narrow streak of pale lilac-blue, while in C. c. chrysops the whole of the cheeks
