respect with South Brazilian examples. The wing measures 112, the tail 89}, the 
bill 194 mm. From M. 6. atronitens Cab. (ex Para, Guiana, Orinoco delta, etc.) it 
differs by its much larger size and stronger as well as longer bill; from 
M. b. venezuelensis Stone by its stouter bill and decidedly purple (not steel-blue) 
coloration.

The specimens agree with others from Cayenne, Surinam, and Panama. The

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. ¢. chrysops from Paraguay and Southern Brazil (S. Paulo), the adult bird differs in 
many important particulars. The feathers of the pileam are somewhat stiffer and 
much more elongated, the longest measuring fully 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 rectrices 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. ¢. chrysops the whole of the cheeks
