Proceedings of the Zoological Society of London Volume 24 (Paperback)


This historic book may have numerous typos and missing text. Purchasers can download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1856 Excerpt: ...specific identity of the two whales. These differences are as follows: --In the Laman whale the superior and inferior transverse processes of the 5 th cervical vertebra are united, and the lower process of the 6th short; whereas, in the Copinshay whale, the transverse processes of the 5th are not united, and the lower process of the 6th is as long as those of the 3rd, 4th, and 5th. Still, with deference I submit, that when all the other resemblances are taken into account, these variations cannot be considered essential. I think it will be more easy to point out specific characters in the bones by the union or disunion of the processes of the 2nd cervical vertebra; by the comparative length of processes as regards the body of the vertebree, and by the form and angular aperture of ring, than by the circumstance of the lateral processes after the second being-united or not. At any rate, I cannot readily imagine that the union or separation of the 5th, and still less so the length of the lower process of the 6th, can be of great value. In this last, the specimen in the Zoological Gardens of Edinburgh and your own set up in the Museum differ, while they certainly resemble each other in every other way, and are evidently of the same species. I feel sure, that drawings of the dorsal aspect of all these bones of all the species known to you will show considerable and tangible differences, especially in the comparative spread of the processes as you approach the dorsals; in their varying progression in thickness, --gradual in the Laman and Copinshay whales, sudden from the 7th cervical to the 1st dorsal in P. antiquorum. Our Orkney whales seem to resemble your P. boops in some respects, but then the processes are in the Laman and Copinshay whale, they fall somewhat t.
