346 OUTLINES OF PERIODICAL LITERATURE. 



fishes, with descriptions of new genera, comes from Prof. M uller and Dr. 



Heule. Of the Scythian family of Sharks, the characters of six genera 



pristiurus, chilosci/lliiim, hfmiscyllium, crossorhinus, ginyh/mosioma, and stegosto- 

 ma — are delineated. In the second division of sharks, there are five genera 

 — charcharios, scoliodon, zygoma, ttinomobon, and leptocharias, which are desti- 

 tute of spiracles ; and in the galeonrrda, lo.rodon, and galeus, these organs are 

 present. Five genera — lamna, o.ryrrhina, caneharodon, selache, and rineodon — 

 are distinguished : in them, every trace of a membrana nictitans eluded de- 

 tection. 8. In remarks on the species of the genus Mustela, by the Prince 

 of Musignano, the M. erminea, M. cirognanii, M. boccamela, M. vulgaris, M. 

 richardsonii, M. longicauda, and M. prwnata, with their localities, are distinct- 

 ly specified. 9. Mr. Chambers particularizes the rarer indigenous plants 

 growing in the neighbourhood of Tring, and he adds a just admonition to 

 those botanical pedlars whose selfish rapacity in devouring specimens has 

 occasioned the extirpation of many scarce vegetables. 10. Mr. Charles- 

 worth's notice of the remains of vertebrated animals occurring in the ter- 

 tiary beds of Norfolk and Suffolk, is transferred from the sixth report of the 

 British Association. 11. Remarks on the production of chrystals, by Mr. 

 Morris, report his opinion that, in our secondary strata, some of the sulphur 

 has an animal origin, and is combined in a state of sulphuret and sulphate 

 through all the argillaceous deposits. 12. Mr. Luxford relates his discovery 

 of the Cucubalus bacSifer, the berry-bearing chickweed, in the Isle of Dogs ; 

 and, in the mean time, he considers it as a naturalized plant. As articles of 

 intelligence, we have a report concerning a female Orang recently added to 

 the menagerie in the Zoological Society's gardens, and an account of scienti- 

 fic expeditions: and, for short communications, there are papers on the 

 transmission of experience in birds in the form of indistinct knowledge ; on 

 the singular effect produced by change of temperature on small birds ; and 

 on the substitution of a new generic name, Thetis, for the second genus of 

 Proteus in the class of infusorian animalcules. 



XIV Notes on Mr. Cross's Aearus, by M. Turpin, who names it the A. 



horridus, in an English translation, are illustrated with a very distinct micro- 

 scopic figure : the editor justly records his judgment that the foreign natu- 

 ralist has not handled his subject in the most philosophic manner. 2. Expe- 

 riments instituted by Mrs. Power with a view of ascertaining how far 

 certain marine sestaceous animals possess the power of renewing parts which 

 may have been removed, were attended with satisfactory affirmative results. 

 3. Another section is contributed to Dr. Wiessenborn's observations on the 

 influence of man in modifying the zoological features of the globe. 4. With 

 a description and figure of a species of Pay -fish, the sandy ray, not hitherto 

 included in the British Fauna, Mr. Couch introduces this inhabitant of the 

 ocean to the notice of English naturalists. 5. From a consideration of his 

 observations on the existence of saline combinations in an organized state in 

 vegetable structures, Mr. Bird deduces the opinion that the saline matters 

 existing in the tissues of plants play a part in the economy of vegetable life 

 which is as important as that of their other constituents; and that all prin- 

 ciples, except carbon, hydrogen, nitrogen, and oxygen, are not foreign to ve- 

 getable structure. 6. Mr. Clarke communicates a second part to his illustra- 

 tions of the geology of the south-east coast of Dorsetshire, with four sections 

 of the stratification. 7. The generic characters of cartilaginous fishes, by
