The Horn-billed Puffin 
in June breeding upon the Farallon Islands. It is significant, however, that Heer- 
mann did not find the Cassin Auklet ( Ptychoramphus aleuticus), which now breeds upon 
the Farallons by thousands, but he expressly says of the latter, “They abound on these 
islands during the winter, but on my return in spring they had already left to pass their 
summer in more northern climes”!]

WE SHALL never be done, I suppose, quarreling with the bird 
names which an uncritical—or over-imaginative—generation has left us. 
Cerorhinca monocerata has been known in ornithological literature as the 
“Rhinoceros Auklet.” The bird, however, is not an “auklet” at all, but a 
puffin (as its egg clearly shows); while the name “Rhinoceros” based upon 
the possession of a deciduous horny knob on the beak is, to say the least, 
a rather broad joke. The name Horned Puffin would have been more 
appropriate, but some other chap with a superheated imagination got 
ahead of us by tacking that name upon Fratercula corniculata , because, 
forsooth, it has a fleshy protuberance upon the upper eyelid! We shall 
have to fall back then upon the exactly descriptive designation “Horn¬ 
billed Puffin,” and so have the terrors of nominal similarity, rather than
