feet descriptions make it more difficult to judge of his species from them alone. 

 Sorex chrysothorax D. is probably Crocidura leucodon ; Reichenbach, however, 

 is disposed to refer it to C. thoracica ; Micromys agilisD., not distinct from Mus 

 minutus Pallas; My oxus speciosu&T)., probably M. avellanarius ; and Musculus 

 mollissimus D-, nothing more than a common white mouse. (Kaup) Synopsis of 

 the families, genera, and species of Eels — p. 41-77. To make the order Apodes 

 a natural one, Kaup considers it necessary to restrict it to the families Ophisuridse, 

 Anguillidae, Muraenidse, Congeridae, and Synbranchidae, thus excluding the Gym- 

 notidae and Leptocephalidse, as well as Ophidium and Ammodytes. The genera 

 Alabes, Saccopharynx, and Gymnarchus are also excluded ; as to their true syste- 

 matic place the author is not yet decided. The Gymnotidae he considers as 

 constituting the lowest form of the Order Physostoma, the genus Sternarchus, as 

 the highest organized of the family, being assimilated to the Salmonidae in certain 

 points of structure. The Leptocephalidse, in like manner, hold the lowest rank in 

 the Order to which the Esocidae belong, a genus of this family, Esunculus, from the 

 Mediterranean, presenting the other characters of the Leptocephalidse, but 

 possessing ventral fins. (Same) Synopsis of the family Gymnotidae ; with figures 

 — p. 78-87. (Same) Synopsis of the sub-family Ophidinse— p. 93-100. As 

 Fierasfer dentatus Cuvier varies much in the dental formula, Kaup concludes that 

 Echiodon drummondii Thompson is not distinct from that species. Fierasfer 

 imberbis Cuvier should bear the name F. acus, Gmelin's trivial name being the 

 oldest that applies to the species, since Ophidium imberbe L., which Montague has 

 figured in the Transactions of the Wernerian Society, does not even belong to the 

 same genus. (Same) On the swimming bladders of Carapus incequilabiatus 

 Valenciennes ; and Note by Troschel ; with figures— p. 88-92. It appears that two 

 species not easily distinguishable from each other outwardly, yet differ in the 

 number of these organs, that named having three swimming bladders, while C. 

 fasciatus has only two, the ordinary number. (Moebius) Comparative view of 

 the nests of the social Wasps; with a plate — p. 321-332. A summary of an essay 

 on the same subject more at large, published by the author in the third volume of 

 the Transactions of the Natural History Society of Hamburgh. (Gerstsecker) 

 Carcinological essays; with three plates — p. 101-160, Contain many valuable 

 observations on the characters of various genera of Malacostraca, and a critical 

 determination of the species of Herbst, from the originals, now mostly extant in the 

 Berlin Museum. The following new genera are characterized and figured : — Pelo- 

 ■plastus, n. g., of fam. Oxyrrhyncha ; P. pallasii, n. sp. Cyclometopa, Chalcepus, 

 n. g., Cancer trispinosus Herbst; Polycremnus, n. g., C. ochtodes Herbst; both 

 species doubtingly referred by Milne Edwards to the genus Panopseus ; Euctenota, 

 n. g., E. exasperata, mexicana, n. sp. Catometopa, Rhaconotus n. g., R. crenu- 

 latus n. sp. Astacini, Scytoleptus n. g., S. serripes n. sp., South African. Spbsero- 

 midse, Monolistra n. g., M. cozca n. sp. from the Cam iolan caverns. The following 

 are new species of other genera : — Micippe miliaris from the Red Sea ; Trapezia 

 corallina, subdentata, Lupea exasperata, pudica ; Gelasimus excellens, allied to 

 Acanthoplax insignis Edw. ; Dilocarcinus pardalinus ; Telphusa subquadrata, 

 Philippine Isles. Lambrus carenatus Edw. is the true C. pransor Htrbst, and L. 

 prensor Edw. is renamed L. edwardsii. There is some difficulty in determining 

 which of two very similar species of Ocypode is the true Cancer ceratophthalmus 

 Pallas; but his figure and the habitat are in favour of the species figured by 

 Desmarest as O. ceratophthalmus, and to which C. cursor Herbst belongs. The 

 other species, which M. Edwards appears to have confounded under the same name, 

 stands here as O. cegyptiaca. O. pallidula Dana may very probably be the young 

 of the former species, as the black markings are common to all of this genus at a 

 younger age. Uca una and lsevis Edw. should be united as male and female of one 

 species. Dilocarcinus castelnaui Edw. is Cancer septem dentatus Herbst ; Cancer 

 hydrodromus Herbst Telphusa grapsoides Edw., and C. aurantius Herbst T. 

 leschenaultii Edw., so far as Milne-Edwards's brief descriptions admit of a judg- 

 ment being formed. (Leuckart) Notes on the Medusae of the sea of Nice ; with 

 two plates — p. 1-40. A valuable contribution both to the Anatomy and Natural 

 History of Coelenterata. The following new genera are characterized, Calyptra,
