"This species is represented in the collections of the Smithsonian Institu- 

 tion by numerous crania, some skeletons and a colored cast of the natural 

 size, taken by the United States Commission of Fisheries, near Portland, 

 Maine" (Cope). 



"The foregoing locality is, I believe, incorrect. It should be Woods Hole, 

 Mass., or else Cape Cod. I think cast No. 12939, Woods Hole, Mass. 

 (original No. 3), and the whole series of skulls and mandibles, Nos. 14228 to 

 14326, 14335 and 14362 to 14373, are to be regarded as cotypes. No. 14335 is 

 marked 'Skeleton without a head,' but it is on exhibition and there is a skull 

 on it now. This seems to be the only skeleton in the lot." F. W. True, 

 manuscript note.
