(1) A skeleton 16 ft. 54 in. long from off Monomoy Pt. Lighthouse, Harwich- 
port, Massachusetts, in the U. S. National Museum. (No. 20931, from the U. S. 
Fish Commission, 1883.) 
(2) Measurements, description, and sketches of a female, 15 ft. 4 in., entangled 
in the nets of the fishermen near Portland, Maine, in July, 1898, and exhibited in 
that city. I owe the data relating to this specimen to Joseph P. Thompson, Esgq., 
Vice-President of the Portland Society of Natural History. 
(3) Two photographs of a female, 22 ft. 8 in. long, captured near Quoddy 
Head Life-saving Station, Maine, Sept. 6, 1889, and reported to the Smithsonian 
Institution by Capt. A. H. Myers, keeper of the station. 
An imperfect skull was dredged up near Pigeon Cove, Mass., in 1881, and 
sent to the National Museum, by Mr. Wm. H. Jackson. It is not now accessible.

in the form of the dorsal and pectoral fins. The color markings on the external face 
of the pectoral fin are exactly as in that species, as is shown by Mr. Thompson’s 
excellent figure (text fig. 52). His notes on this specimen are as follows: “The 
color of the body was an ashy black above, passing into a pure white on the belly, 
without any distinct demarkations; nor was there any apparent lateral line. The 
blowhole was in a sunken cavity. The eye was very near the corner of the mouth. 
The number of longitudinal furrows could not be accurately counted, though they 
were very strongly marked, of a pinkish color within the folds, and white without. 
The baleen was of a pinkish brown at the bases of the plates and fading in color
