CERORHINA SUCKLEYI, Cassin. 
Sp. Cu.—Smaller than the preceding, and with the bill much more narrow laterally ; plumage darker. Bill shorter than the 
head ; upper mandible curved towards the end, without distinct basal knobs ; under mandible with the angle very distinct ; bill 
rather widened at the base, compressed towards the end; wings short; tail very short. Entire upper parts brownish black, 
darker and nearly clear black on the head and back. Throat, neck, and upper part of breast dark cinereous ; lower part of 
breast and abdomen white ; sides and under wing coverts cinereous ; bill light at base, dark at the end; feet dark yellow. 
Total length about 124 inches; wing, 63 inches; tail, 12 inch. 
Hab.—Steilacoom, Puget’s Sound, (Dr. Geo. Suckley.) 
This species is smaller than the preceding and darker in color, especially on the upper surface 
of the head and body. The bill also is much more slender. The only specimen that we have 
ever seen is in the collection*made by Dr. George Suckley, U. 8. A., whose name we have taken 
the liberty of applying to it, as a slight testimonial to his great zeal and ability as a naturalist 
and scientific traveller. 
According to Dr. Suckley, this species is said by the Indians to be not uncommon on Puget’s 
Sound. He further states that in life the membrane at the base of the upper mandible is 
grayish dusky, the knob (!) slightly more*greyish. The middle of both mandibles dingy 
orange, their tips dusky. Iris pale hazel. Under surface of toes bluish white, darker about 
the articulations ; nails black.
