Sorry, no etymologies found.
One important remark has been made, that a comparatively small variety of species is found in the older rocks, although of some particular ones the remains are very abundant; as, for instance, of a species of asaphus, which is found between the laminae of some of the slate rocks of Wales, and the corresponding rocks of Normandy and Germany in enormous quantities.
The cephalaspis may be considered as making the smallest advance from the crustacean character; it very much resembles in form the asaphus of lower formations, having a longish tail-like body inserted within the cusp of a large crescent-shaped head, somewhat like a saddler's cutting-knife.
