ALLEN: NEW ENGLAND WHALEBONE WHALES. 



Measurements of the Cape Cod 1895 male (from J. H. Blake). 



Tip of lower jaw to notch of tail 



" " upper jaw to corner of mouth 



" " " " to blowholes 

 Greatest vertical thickness of lower lip 

 Axial length of blowholes 

 Distance between posterior tips of blowholes 

 Tip of lower jaw to anterior insertion of pectoral 

 Posterior corner of eye to anterior insertion of pectoral 

 Anterior border of pectoral from insertion to tip 

 Greatest width of pectoral (from posterior corner) 

 Anterior insertion of pectoral to penis 

 Anus to notch of tail 



Caudal notch to anterior insertion of fluke 

 Posterior border of left fluke (straight line) 

 Ventral distance between anterior insertions of pectorals 

 Longest baleen 



These measurements and proportions show a rough general agreement but indicate the 

 somewhat more slender build and relatively shorter head of the smaller (female) specimen. 

 Andrews (1909a, p. 274) has given the measurements of a young female 27 feet 9| inches in 

 total length, taken off Amagansett, Long Island, on December 10, 1908. He points out that 

 the pectorals and the flukes are much larger in proportion than in adult specimens. It is 

 interesting also that in this young whale, perhaps not more than a year old, the 'bonnet' was 

 well developed, and infested with Cyami, as were also the roughened areas on the jaws. 



Skeleton. 







Skull. Apparently the only New England skeleton of this species preserved in any 

 museum is that in the Museum of Comparative Zoology at Cambridge, taken off Provincetown 

 in April, 1864. This is now mounted and hangs from the ceiling of the main hall. It was 

 studied and measured by Dr. J. A. Allen soon after its reception, and his account of it with 

 illustrations has lately been published (J. A. Allen, 1908). He gives the following cranial 

 measurements, which I have reduced to percentages of the total length of the skull.
