94 THE WHALEBONE WHALES OF THE WESTERN NORTH ATLANTIC. 
Cape Cod, Mass. The coronoid process of the mandible is prominent in both these 
specimens, and in No. 21492 increases the total depth of the jaw from 10 inches to 
12 inches, though as it is strongly inclined outward, the vertical height of the 
process itself exceeds 3 inches. In JZ. longimana, furthermore, if Struthers’s speci- 
men is to be regarded as representing that species, the coronoid is not inconspicuous. 
Struthers’s measurements are—anterior margin 1} inches, posterior margin 31 inches. 
As no measurements are given by Cope for J. osphyia, it is difficult to estimate the 
exact import of the word “rudimentary” which he employs. An examination of 
the type shows that the coronoids have been cut off at the top. Whether they 
were in this condition when Cope saw them is uncertain, but probable. The 
coronoid is, of course, less well developed in the Humpbacks than in the Finbacks. 
We have now reviewed all that has been recorded of the type of JZ. osphyia, 
and it will be conceded, I think, that there is no reason to suppose that it should 
be separated from other specimens from the Atlantic coast of the United States, as 
a distinct species. Whether the American species is different from the European 
longimana—the main question at issue—will be considered later. 
The type-skeleton of JJ. osphyia is figured on pl. 36. As already stated, it 
was formerly in a small museum on the Canadian side of Niagara Falls, but has now 
been removed to a new museum building near the Cataract Hotel on the American 
side. A written label on the skeleton reads: 
“Skeleton of a whale 50 ft. long. Caught by Capt. Bickford, of the ship 
Fulton, near the Petit [Manan] Lighthouse, on the coast of Maine, July, 1844. It 
weighed about 70 tons. The jaw bones measured 12 feet. 18 people can sit in 
its mouth. It was towed into Birch Harbor, and there prepared for exhibition. It 
is the only specimen of its kind known.” 
A printed label says: “. . . weighing about 70 tons, it was captured by 
Captain J. Bickford, of the ship Futon, on the coast of Maine, 40 miles at sea, 
Petit Manan Light House, July, 1844,” ete. 
The skeleton is mounted with all the vertebra, except the atlas, reversed. 
The curvature of the dorsal region is exaggerated. Each pectoral limb has three 
digits, and three phalanges in each digit (exclusive of metacarpals), an entirely 
artificial arrangement. 
Actual measurements of the skeleton, made by myself in 1900, are as follows:
