BLUE WHALE. 257 



a whale 75 feet long was washed ashore dead, at Popham Beach, Maine, about the first of 

 November. If the measurement is correct, it indicates a Sulphurbottom. 



1912. Dr. Henry B. Bigelow furnishes me a note of a large whale seen by him about 5i 

 miles SE. by S. i S. from Cape Elizabeth, Maine, whistle on August 7th, which from its size 

 and its small dorsal fin as compared with that of Common Finbacks seen at the same place, 

 was without much doubt a Blue Whale. 



Enemies and Parasites. 



Our knowledge of the enemies of the Blue Whale is practically nothing. No external 

 parasites are recorded for this species, but no doubt it may lodge Penellae at times. It is 

 normally quite free of barnacles. 



Malm (1867) described and figured a new species of parasitic worm, Echinorhynchus brevi- 

 collis, from the small intestine of a Blue Whale stranded on the Swedish coast. It is one of 

 the so called thorn-headed worms, that anchors itself to the inner lining of the intestine by its 

 head from which project numerous small thorn-like processes. Its body lies free in the intestine 

 and absorbs nutriment from the digested food.
