Prof. Muller, are resumed, with his descriptions of new genera — the triglo- 

 chis, alopecino, cestracion, acanthias, spinax, centrina, centrophorus, scym- 

 nus, laemargus, echinarhinus, squatina, pristiophorus, rhina, rhynchobatus, 

 rhinobatus, platyrhina, trygonorrhina, sympterygia, uraptera, trygon, hemi- 

 trygon, himantura, pteroplatea, tseniura, hypolophus, urolophus, anacanthus 5 

 nrogymnus, myliobatis, aetobatis, cephaloptera, and ceratoptera. 8. Dr. A. 

 Smith's farther contributions to the natural history of Southern Africa, are 

 his remarks on the Naja nigra, N. gulturalis, Vipera ocellata, Lacerta elegans, 

 L, lesselala, L. livida, L. tceniolatc, E. intertexto, L. etenodaetylus, L. undata, 

 L. lugubris, L. capensis, and the Algyra capensis. 9. Some mistakes of M. 

 Coste, the French naturalist, are corrected by Mr. Owen, respecting the 

 nllantns of the kangaroo and its embryology. 10. Mr. Sowerby describes a 

 new genus of Trochidea, belonging to the family of phytophagous gastero- 



podes : he designates it T. morrisii, and gives a good figure in illustration. 



11. In a succinct note on the ltaputia aivmatica, Mr. Hancock advances his 

 reasons for concluding that Raputia not only forms a part of the order Cvspa- 

 ridew, but that it is itself a true and legitimate species of the genus Galipea .- 

 he trusts to find his statements confirmed by further investigation. 12. 

 The observations upon the best mode of preserving marine productions, by 

 Mr. Harvey, recommend themselves, by their manifest excellence, to the 

 attention of the practical naturalist. For scientific notices, there are, the 

 substance of a communication from Air. Crosse to the Electrical Society ; 

 notes on the Angustura-bark and its botanical characters, on the "Victoria re- 

 gia and the Euryale amazonica ; an extract from the report of the botanical 

 society; an account of the discovery and denomination of anew species of ai>- 

 tilope, the A. nigra, of which no other other individual has yet been seen in 

 Europe, or indeed known to African travellers ; and the latest information 

 relating to scientific expeditions. Some instances of longevity in animals — a 

 parrot and a nightingale — stand in the place of short communications. 



XV — M. Desnoyers, in an English version, offers some considerations 

 upon the position in the Tertiary System, to which the faluns of the Loire 

 and the crags of England ought to be referred ; and upon the difficulty of 

 determining their relative age, solely by the law of the proportional number 

 of fossil species analogous to species now in existence : appended to these 

 considerations, is a temperate and valuable note by the editor, and in this he 

 regrets being compelled to notice an instance of undue appropriation on the 

 part of the continental naturalist. 2. Meteoric observations made in Ger- 

 many in November of last year, are communicated by a lady. 3. From Dr. 

 Weissenborn, we have another portion of his essay on the influence of man 

 in modifying the zoological features of the globe : his discussions here relate 

 to the common wolf, and he closes them with the saying, " Censeo lupum f'un- 

 iliius m$e dclrndiim." 4. With five figures for the exhibition of characters 

 Mr. Clarke concludes his illustrations of the geology of the south-east of 

 Dorsetshire. 5. Mr. Dalrymple furnishes some account of a peculiar struc- 

 ture in the eyes of fishes, and this is represented in two well-executed dia- 

 grams. 6. A few notes on the British species of the genus Polypodium, bv 

 Mr. Newman, relate to the P. vufgare, P. phegopteri*, P. dryopteris, P. thelyp. 

 teris, V.onnpieris, P. cristalum, P. jM&mai, P. dilatalum, P. lonchiih, P. /,«. 

 pile, and P. UvmMi his synoptical new of characters, with the introductory 

 remarks, are perspicuous and practically valuable. 7. Mr. Ogilby's charac-
