In the majority of specimens the last pair of ribs is much shorter than the 
penultimate pair, but in the Raleigh Museum skeleton the last left rib is nearly as 
long as the rib which precedes it. The right rib is shorter. 
STERNUM. 
Among European specimens the sternum appears to have been figured only in 
the case of the Taranto skeleton and Guldberg’s Iceland skeleton No. 1. These

two sterna (text figs. 85 and 86) show little resemblance to one another at first sight ; 
nevertheless, it will be perceived that if that of the Taranto skeleton were length- 
ened posteriorly it would approach that of the Iceland specimen, the form in both 
cases being rudely heart-shaped.
