250 THE WHALEBONE WHALES OF THE WESTERN NORTH ATLANTIC. 
Among the American specimens, we find that the Charleston whale was en- 
tirely black. The Egg Harbor, New Jersey, whale was also black. 
The Cape Lookout specimen, captured March 20, 1894, a female, was said to 
be a “white-bellied” one. The figure published in the Bulletin of the North 
Carolina Dept. of Agriculture (14, No. 7, April, 1894, p. 4) shows the whole under 
surface light colored, from a point in advance of the eye to the anus, the white 
area extending up to the base of the pectorals and having irregular margins. If 
the drawing was correctly made from the specimen itself, it indicates a remarkable 
color variation. In a letter Mr. H. H. Brimley remarks that this specimen had 
“a great deal of pure white on its under side.” 
The foregoing facts may be summed up as follows: 
Three specimens of the European Nordcaper are recorded as being entirely 
black, and the Iceland specimens were also black, with the exception of one young 
one, which was reported to be lighter colored on the belly. Of three American 
specimens, two are recorded as entirely black, and one (adult female) as having “a 
great deal of pure white on its under side.” (See pl. 46, figs. 1 and 2.) 
OSTEOLOGICAL CHARACTERS—-NUMBER OF VERTEBR&. 
The skeleton of the European Nordcaper has been described in detail and 
figured by Gasco (47 and 48), Graells (52), Capellini (13), and Guldberg (59). 
The skeleton of American specimens has been described and illustrated by Holder 
(61) and Manigault (68). (See pls. 42-46.) 
The number of vertebrze has been given by these authors for several individ- 
uals, as follows :

Gasco gives 13 pairs of ribs, but thinks there may have been 14 pairs. Hence, the formula 
was perhaps 7, 14, 12 (or 11), 23 (or 24) = 56. 2U.S. National Museum, No. 23077,
