THE WHALEBONE WHALES OF THE WESTERN NORTH ATLANTIC. 143 
graph (69) shows this bone as having the central part of the spinal border straight, 
the posterior part sharply bent downward, the anterior part somewhat so, and the 
acromion well raised above the level of the glenoid fossa. Sars’s drawing (77, pl. 
3, fig. 10) of a Lofoten Ids. specimen is intermediate between Menge’s and those of 
Fischer and Malm. (See text fig. 33, p. 142.) 
In the type of B. tectirostris (Cope) from Maryland (text fig. 35 ; pl. 6, fig. 2) the 
scapula is of the same form as shown in Menge’s photograph of the Danzig specimen, 
as is that of the Cape Cod (Mass.) adult in the Albany museum, and the National 
Museum specimens Nos. 16039 and 16045, also from Cape Cod (text figs. 35 and 
36; pl. 7, figs. 1 and 2). Dwight writes of the Gloucester (Mass.) specimen: “The 
superior border [of the scapula] is pretty regularly curved, except that toward the 
last fourth it inclines rather suddenly downward” (85, 222). 
The greatest length of the scapula in three adult European specimens is 27.6 % 
of the length of the skull. In the Albany museum (N. Y.) adult it is 27.9 7, and 
in three immature American specimens 25.3 % In two European specimens the 
radius is 17.2 % the length of the skull, and in two American specimens 17.5 %. 
The number of phalanges found in specimens mounted in museums is commonly 
reduced from the natural number by the loss of one or more pieces in the process 
of maceration to remove the flesh. The numbers included in the following table 
are probably quite complete. Those quoted from Struthers and Dwight represent 
their own dissections. The metacarpals are excluded :

2Includes the pisiform cartilage. The formula is for the left side. The right side had the 
following: IL.,4; IIL,6;1V.,5;V.,2. “Norwegian measure. * Plus one “encore cartilagineuse.” 
® Kiikenthal’s formule include one more phalanx in each digit than given above, but it is 
obvious from his figures that the metacarpals are included. His remark, that these specimens con- 
firm the law that more phalanges are present in the embryo than in the adult, does not, therefore, 
hold good when Struthers’s Wick (Scotland) specimen is considered. (Anatom. Anzeig., 5, 1890, 
Pp. 59, 51.)
