L. antiqua^ sp. n., Alcock, I, c. p. 176, pi. 4. lig. 3, Dogs’ Bay. Some very 
interesting varieties or monstrosities of species of Lagena and Glohigerina 
are also figured in this paper of Dr. Alcock. 
Rhabdammina abyssicola is the name given by Sars to a noAV llhizopod, 
not yet, so far as we can learn, described by its discoverer. {Vida Sars, 
Mdm. pour servir a la connaissance des Criuoides vivauts, p. 52.) 
Coccoliths, 
Professor Huxley (1. c.) supposes that the stickiness of the mud from the 
bottom of the Atlantic arises from its containing innumerable lumps of a 
transparent gelatinous substance. When one of these minute lumps is sub- 
mitted to microscopical analysis it exhibits, imbedded in the structureless 
matrix, granules, coccoliths, and foreign bodies. The granules vary in size from 
4o6oo 8^’ I’ounded, some are biconcave oval disks, 
others are rod-like, some are irregular. The coccoliths have been imper- 
fectly described, both by Professor Huxley in his original paper and by Mr. 
Sorby. They include two distinct kinds of bodies, now called Discolithus and 
Cyalholithus j these are described in detail and figured. The coccosplicres 
are also of two types — the one compact, the other loose in texture. 
Bathybius, 
Professor Huxley conceives that the granule-heaps 'and the transparent 
gelatinous matter from the bottom of the Atlantic represent masses of proto- 
plasm, which, he thinks, may be regarded as a new form of Hackel’s Monera. 
He gives to this Moner the generic name Rathybius, and calls it B. hdckcHi. 
He is led to believe that the Discolithi and tlie Cyatholithi stand in the 
same relation to Bathybius as the spicules of Sponges or of Badiolaria do to 
the soft parts of those animals. It is very probable that the coccospheres aro 
in some way or other closely connected with the cyatholiths. Quart. Journ.
