able to bore into tlie sand. Progressive movements are begun by the 
other pieces if they are stimulated. 
The author concludes that in Worms, as in higher animals, it is the 
anterior end, provided with the brain, that chiefly defines the biological 
and physiological character of the species ; there is no consciousness in 
W onus, and there is no parallelism between the cerebral formation of 
the several species and their systematic position. 
a. Annelida. 
Polychseta of Dinar d.* — M. le Baron de St. Joseph commences the 
third part of his account of the Polychaeta of the coasts of Dinard with 
a description of Nephthys and its allies. The rare Glycera gigantea , 
which is 28 to 30 cm. long, was found only once. Goniada emerita was 
likewise only found once, and the specimen was incomplete. It is 
thought best to keep Ephesia distinct from Sphserodorum ; E. peripatus 
is very rare at Dinard. The Cirratulidae are divided into those with 
and those without large prehensile tentacles, and some suggestions are 
made as to the redistribution of the genera. The characters of Hetero- 
cirrus are emended, and H. caput esocis , H. flavoviridis, and H. Marioni 
spp. nn., are described. 
The granitic rocks of Dinard are unsuitable for the Polydoridae, which 
can only hollow out their homes in calcareous rocks ; P. pusilla is a new 
species. An account is given of various larvae of Nerine. The complete 
description given by McIntosh of Magelona papillicornis makes it un- 
necessary to describe this species at the length devoted to most of the 
species mentioned in this memoir. 
The Scalibregmidae may be divided into those with and those with- 
out gills ; the characters of Sclerocheilus are emended. Lipobranchus 
intermedius is a new species, with affinities to Sclerocheilus. Armandia 
Dollfusi sp. n. is described from a single example, but appears to be 
distinct from the species already known. 
The “ synonymy ” of Arenicola marina extends over nearly two 
pages ; the largest examples are 25 cm. long. A new classification is 
proposed for the Maldanidae, and the characters of some of the genera 
are emended, while a short diagnosis is given of Maldanella , which was 
not defined by its author, Prof. McIntosh. Maldane (?) cincta sp. n. is, 
perhaps, a Maldanella. 
There is a long and detailed discussion of the characters of the 
Terebellidae, and classification of the genera is proposed ; of these Pherea , 
Bathya, Proclea , Phisidia are new. The Serpulidm are somewhat simi- 
larly treated, Erato being the only new genus. 
Septal Glands of Oligochseta.t — Dr. E. Hesse finds an essential 
agreement in the composition of the septal glands of various Enchytraeidge, 
of Tubifex , Psammoryctes, Limnodrilus, and Lumbriculus , so that he con- 
cludes that in all Oligochaeta these septal glands are bundles of uni- 
cellular glands. The separate gland-cells are altered cells of the 
pharyngeal epithelium, which, by an extraordinary elongation of their 
distal ends, have separated from this epithelium, and have grown into
