The specimen upon which the species was based by Mr. Lawrence, 

 collected at Fort Yuma, by Dr. Leconte, still remains unique, and 

 of H. crissalis a second specimen only has been obtained. It is not 

 a little remarkable that two species so large and conspicuous should 

 be both from the same region, and so very rare. With much the 

 same shade of coloration, H. crissalis is a little darker, the under 

 tail coverts deep chestnut instead of rusty fulvous ; the bill is much 

 longer and more slender, the tail also much longer.

A second specimen (11,533) of this rare species is larger than the 

 type, but otherwise agrees with it. Its dimensions are as follows : — 



Length before skinning, 12.50; of skin, 12.50; wing, 3.90; tail, 6.50; its 

 graduation, 1.45 ; 1st quill, 1.50 ; 2d, .41 ; bill from forehead (chord of curve), 

 1.65, from gape, 1.75, from nostril, 1.30; curve of culmen, 1.62; height of 

 bill at nostril, .22 ; tarsus, 1.30 ; middle toe and claw, 1,12. 



The bill of this species, though not quite so long as in redivivus, 

 when most developed, is almost as much curved, and much more 

 slender — the depth at nostrils being but .22, instead of .26. The 

 size of this specimen is equal to the largest of redivivus (3,932) ; the 

 tail absolutely longer. The feet are, however, considerably smaller, 

 the claws especially so ; the tarsus measures but 1.30, instead of 

 1.52; the middle claw .29, instead of .36. With these differences 

 in form, however, it would be impossible to separate the two 

 generically.
