Cyanocitta pulchra. 



A narrow band on the front next the bill, the lores, the sides of the 

 head and the chin are deep black; entire crown and occiput silvery bluish- 

 white; a band of bright ultramine blue crosses the hiud neck, becoming 

 deeper in color and gradually merging into the smoky black of the upper 

 part of the back, where it inclines to brownish, the lower part of the back 

 and upper tail coverts are deep cobalt blue; wings and tail of a rich co- 

 balt blue, brighter than the color of the body ; the under surface of the 

 wings and tail glossy black; throat cobalt blue, breast and sides of the 

 neck smoky black, abdomen and sides dark cobalt blue like the back, 

 under tail coverts smoky black ending with cobalt blue, thighs smoky 

 brown washed with blue ; bill and feet black. 



Length, 11 in.; wing, 5;j; tail, o£ ; bill, 1|; tarsus, l£. 



Habitat. Ecuador, Quito. Type in my collection. 



Remarks. Compared with O. armillata it is shorter and 

 proportionally stouter, the bill very much stronger and the 

 tail not so long ; it cannot be mistaken for that species as 

 they differ throughout in color and markings. In C armil- 

 lata the vertex, occiput and nucha are of a light blue, which 

 merges into the fine dark ultramarine blue of the back ; 

 whereas in the new species, the silvery bluish- white of the 

 Lead, is separated from the smoky black back, by a rather 

 narrow band of blue ; the throat patch in C armillata is of 

 a clear ultramarine blue, strongly defined and separated from 

 the darker blue of the under parts by a black collar ; in the 

 new species the throat mark is rather dull in color and 

 without any collar below it. It is unlike any species which 

 I can find described, and I compare it Avith C. armillata that 

 its characteristics may be more clearly elucidated.
