Excerpt from Proceedings of the American Academy of Arts and Sciences, Vol. 36: From May, 1900, to May, 1901 The large hand evidently belonging to this species is marked in exactly the same manner on the outer aspect as in C. Borealis, having the four distinct raised granulated lines or ridges, with the same arrangement as in the living species. The single specimen lacks the articular face at the base, as also unfortunately the fingers, and also the Spine at the base. Of the four ridges on the inner face, on the lowest ridge there are 32 papillae, or conical granulations; on the ridge above, where they are much smaller, about 33; in the third ridge there are two rows of conical granulations, one consisting of 20 large ones, with a parallel row of minute ones below; on the fourth ridge there are about 12 - 14 large granulations, with smaller ones situated irregularly on the lower side, while some others are interpolated between the large ones. The concavities between the ridges are well marked. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
