of natural freedom. 4. Mr. Gray gives an account, with denominations, of 

 spme new species of quadrupeds and shells procured from Sierra Leone ; and 

 two of the former are characterized. He represents the Antilope zebra as 

 the most brilliant of all the kindred tribes; and his Felis neglecta is a highly 

 interesting animal, in size like a small leopard. Fourteen different kinds of 

 shells are distinguished and named, by this ingenious naturalist : these are, 

 Aporrhais senegalensh, Fusus e/egans, F. niveus, Nassa vitrea, Cardium /are, 

 Turbinella spinosa, Drillia umbilicata, D. clathrata, D. bicolor, D. suiuralis, 

 Demoulia pulchra, Buccinum retusutn, Pleurostoma tenuh, and Mactra sauli- 

 ana so " named in honour of Miss Saul of Poplar a most industrious and libe- 

 ral collector of shells." The drillia and demoulia are new genera : the latter 

 is intermediate between the nassa and dolium, and their diagnostic features 

 are here described. 5. This is a translation from the first volume of the 

 Mbmoires'de la Societe des Sciences Naturelles de Neufchalel, and it forms the 

 prodromus of a monograph of the Ecbmodermata by Dr. Louis Agassis 

 whose paper manifests his profound acquaintance with the subjects of his 

 investigation. C. Observations on the Scottish Mollusca Nudibranchia by 

 Dr. G. Johnston are illustrated with a plate representing sixteen figures. 

 He divides the, tribe into two families, the Doridse and Tritonidse, and then 

 describes eight kinds of the former— the Doris tuberculata, D. obvelata, D. bi. 

 lamellata, D. laevis, D.pilosa, D. nodosa, D. nigricans, and D. barvicensis, with 

 references to their economy. 7- This consists of Letters from Mr. Cuming 

 at Manilla, Dr. Schomburgh at New Amsterdam and Demerara, and Mr. 

 Gardner at the Organ-Mountains in Brazil, with sketches of the observations 

 and discoveries of these adventurous naturalists. 



II. Article eighth of the Annals is Mr. Berkley's anglo-hellenic exercise 

 on the fructification of the Pileate and Clavate tribes of the Hymenomyce- 

 tous Fungi, and this is illustrated by a plate with fifty-seven figures. He 

 traces a history of the state of knowledge, in 1838, respecting the hymenium 

 in the Agaricine family ; and he adduces many facts to confirm his theory — 

 that a quaterniary arrangement prevails in th_> cryptogamous plants. 9. 

 Mr. Gunn's notices accompanying a collection of quadrupeds and fish from 

 Van Diemen's Land, are followed by Mr. Gray's descriptions of new species. 

 Anion" the Mammalia, he specifies the Thalacinus cynocephalus, Phalangista 

 coekii, P. vutpina, P. fuliginoia, Perameles gtmiiii, Phascolomys or wombat, 

 Dasyurus or deril,T>. viverrinus, Hydromys chrysogaster, the Echidna which is 

 harmless and makes good food, and the Kangaroo of four kinds— the boomer 

 or forrester, the brush, the wallabee, and the rat kangaroos. His Fish, are 

 the nurse, leather-jackets, parrot-fish and the sea-horse. 10. Mr. Reade ar- 

 gues, that spiral vessels do exist in the roots of dicotyledonous plants, and his 

 facts in support of this induction appear to be conclusive. 11. His descrip- 

 tion of the Scottish Mollusca is continued by Dr. Johnston; and his subjects 

 are, Tritonia hombergii, T. arborescens, T. plebeia, Melibea pinnatifida, M. co- 

 ronata, Eolidia papillosa, E. cuvierU, E. rufibranchialis, E. purpurascens, F..plu. 

 mosa, E. despecta, Triopa claviger, and the T. nolhiis a beautiful animal, and 

 remarkable for the darkness and disposition of its colours. Mr. Gray was the 

 first to discriminate this genus ; and he has named it in allusion to Triopa 

 one of Neptune's soiis : a plate, with eleven figures, contains his graphical 

 illustrations. 12. Some original remarks on the Genus Torreya are advanced
