oxyuraus. The characters of the genera Erichthonius and Ampelisca are newly 

 defined. (Lindstrdm) Larva of a Peltogaster ; with figures — p. 361-363. This 

 parasite was found on the abdomen of Pagurus bernhardus, and of another 

 species allied to P. cuanensis. It seems related to, if not identical with, Pelto- 

 gaster paguri Rathke. The larva presents some characters which have been ob- 

 served in those of the Cirripedia, but not of the Lernseoda hitherto. ('Same) 

 The invertebrateffauna of the Baltic, with two plat, s — p. 49-73. Pontoporeia 

 affinis, a new species allied to P. femorata, Kroyer. Bathyporeia n.g., having 

 some points of resemblance to Anonyx, but distinguished by the absence of 

 claws to the second and fifth pairs of thoracic feet, the peculiar form of the 

 maxillary feet, and the development of the seventh pair of abdominal limbs. 

 B. pilosa found on a sandy bottom, at a depth of 18-24 fathoms. See the figures 

 given in Plate II. of this Vol., and the accompanying explanation. Observations 

 on the embryology of N eritinafluviatilis L. Cordylophora lacustris Allman has 

 been found abundantly in the Gaalcestrat. It is possible that Tubularia carnea 

 Agardh may be identical, but the description of this last is not sufficiently ex- 

 plicit to inspire confidence. (Same) On the development of Sertularia 

 pumila L. ; with figures — p. 365-374. This presents some points of analogy 

 to that of Campanularia geniculata, as observed by Loven and Schultze. It is 

 probable that the Sertularia is a stage of some Medusa. (Kinberg) New genera 

 and species of Annelida — p. 381 388. The new genera are : — Aphroditacea — 

 Aphrogenia ; Laetmonice, a Swedish species ; Iphionea — Iphione, type Polynoe 

 muricata Sav.; Polynoina — Halosydna; Antinoe ; Harmothoe, Aphrodita scabra, 

 O. Fabr. ; Hermadion ; Accetea — Panthalis, a Swedish species ; Eupompe ; Siga- 

 lionina — Sthenelais ; Leanira; Psammolyce, Sigalion herminiae Aud. et M.Edw. 

 The new species amount to 36 in all. ( Walhberg, P.) New species of leeches — 

 p. 233-234. Sanguisuga javariica, from Java, where it is used medicinally ; S. 

 chloronota, found in different parts of Sweden, perhaps a mere variety of the S. 

 medicinalis. (Walmstedt) The Swedish species of Clausilia — p. 79-87. Six 

 species are here enumerated, of which C. plicata Drap., an addition to the 

 Swedish Fauna. (Loven) On the development of Chiton ; with a plate — p. 169-180. 

 The species on which the observations were made was Ch. marginatus Penn. 

 (C7&. cinereus L., according to Forbes and Hanley.) The circle of cirri by means 

 of which the young larva moves about in its natatory stage, and which are after- 

 wards cast, seerrs to correspond to the cirri of the velum in the young of other 

 Gastropoda and of the Acephala. (Eetzius) On the skull of a Pampas Indian ; 

 with figures — p. 1-6. (Same) On the antrum pylori in man, with figures 

 —p. 219-230. fBoeck) On muscular contraction ; with six plates — p. 257 287. 

 Botany. (Andersson) On the g. Apluda L., with a plate — p. 175-180. 

 Six species are described, of which two as new, A. ciliata and scabra, both East 

 Indian. A humilis Presl. and A. mucronata Steud. are considered to pass over 

 gradually into A. mutica L., so that they cannot be considered specifically distinct. 

 (Same) On Saccharum and the allied genera — p. 151-167. The genera of this 

 group are Saccharum, with seven species, S. ciliare n. sp. from Belaspur in the 

 Punjaub; Imperata, four species ; Erianthus, thirteen species, of which new, E. 

 purpurascens from Belaspur, E. longesetosus, E. Indies ; Miscanthus n. g. includ- 

 ing ftrianthus capensis Nees, and Eulalia japonica Trin ; with which M. sinensis 

 And. has been confounded ; also Saccharum preegrande Steud., M. luzonensis 

 And.; a new species is M. purpurascens And., in Alstroemer's herbarium in the 

 Stockholm Museum, country uuknown, probably Japan or China. (Stenhammar 

 andFloderus) Pulsatilla patens found in Gothland — p. 393. (Fries, E.) Occur- 

 rence of the white truffle, Tuber niveumT>esfont.,m Sweden— p. 139. (Wahlberg, 

 P.) Additional localities of the same — p. 394. (Nylander) The distinctions 

 between Lichenes and Fungi — p. 7-11. The lichens are characterized by a 

 thallus furnished with gonidia, which are wanting in the fungi. The hymenium 

 of the former, treated with iodine, assumes a blue, violet, or red colour, while 

 that of the fungi becomes but slightly tinged with yellow in the same circum- 

 stances. In the present stage of science, however, it is difficult to draw a pre-
