separate M/. terensis from M. similis we reduce this number to six. Three of these are 
found within our limits, viz. the widely ranging IZ. similis, M. cayennensis of northern 
South America, which enters our fauna as far as Costa Rica, and MM. granadensis of 
western South America, which ranges northwards to Nicaragua. 
The last-named bird belongs to the section of the genus which has no white super- 
ciliary mark, the other two to the section where this mark is present. 
Myjiozetetes belongs to the group of genera which have the supranasal feathers and 
bristles very fully developed, so that the nostrils themselves are almost covered ; the 
nostrils are at the lower anterior end of the nasal fossa, are open but surrounded above 
and behind by membrane; the bill is strong, compressed, and rather wide, the width 
at the gape being more than half the length of the tomia; the rictal bristles are long, 
extending along two thirds of the bill; the tarsi are stout and covered with scutelle ; 
the wing is rounded, 2nd, 3rd, 4th, and 5th quills nearly equal and longest, 6th > Ist, 
=7th; tail moderate and very slightly emarginate, <% wing, tarsus =} wing.

This is the oldest known species of the genus, having been described by Linneeus. 
It is, moreover, the only one of this section found in Guiana, so that its determination 
can hardly be a matter of doubt. Its range extends along the northern portion of 
South America, and on the western side as far south as Ecuador. It enters our fauna 
and spreads northwards as far as Costa Rica. Panama specimens were described by 
Mr. Lawrence under the name of I. marginatus, but he compared it with I. simiits, 
from which it can readily be distinguished. 
Salmon, who found its nest at Medellin in Colombia, describes the eggs as white, 
spotted, especially at the larger end, with red; they thus, as might be expected, 
resemble those of I. similis.
