48 Leviathan and Behemoth, Crustaceans. 



upon it in p. 193 — 197. 307 — 320, are discussed in the 

 Edinburgh New Philosophical Journal, the Number for Octo- 

 ber, 1835, by a writer, whose name is not given, who has con- 

 ceived " Mr. Thompson's conclusions .... to be erroneous ; 

 and" has "set down some of what appear to" him " the most 

 decisive proofs that they are so." His own conclusions are, 

 that the leviathan was the crocodile of the Nile, and that the 

 behemoth was " one of the larger herbivorous mammalia," 

 and " some large .... species of the bovine genus of Lin- 

 naeus." The treatise occupies from p. 263. to 281., and is 

 learnedly written. 



It would not have been more than was due to the Magazine 

 of Natural History, had the title of this work been allowed 

 to appear as the repository of a printed exposition of Mr. 

 Thompson's views : this is not the case throughout the thesis 

 cited. A second instance of this injustice occurs in a com- 

 munication in the same Number of the Edinburgh New Phi- 

 losophical Journal, entitled, " On the Falls of Niagara, and 

 the Reasonings of some Authors respecting them. By 

 Henry D. Rogers, F.G.S., of London, &c." Refer to Mag. 

 Nat. Hist. III. 117—130. 



Metamorphosis in, and Habits of, Crustaceous Animals. 

 (II. 244, 245.; IV. 256—259.; VIII. 261—277. 467—469. 

 482 — 486.550,551.) — There is contained in the Entomologi- 

 cal Magazine, No. 13. October, 1835, in p. 275 — 280., a 

 " Memoir on the Metamorphosis in Porcellana and Por- 

 tunus. By J. V. Thompson, F.L.S., Deputy Inspector- 

 General of Hospitals," illustrated by three figures; and, 

 besides, other information on the deemed metamorphoses of 

 crustaceous animals and on the habits of certain species of 

 them, this notification is made: — >'* We have, perhaps, our- 

 selves been somewhat to blame in not allowing it [' Crus- 

 taceology'] a more prominent place in our pages than we 

 have hitherto done. We now announce our intention of 

 repairing this error ; and, aided by the valuable contributions 

 of Mr. Thompson, we hope that no future number will appear 

 without, at least, one article on Crustacea." 



I have stated, in VIII. 468., that ecdysis and transformation 

 are subjects not identical : they are identified, on reasons, in 

 the Ent. Mag., p. 293. of the Number cited above. — J. D. 



Phyllosbma ; Mr. LuJcis has pi^oposed the epithet, sarniense, 

 to designate the species that is described and illustrated from 

 him in p. 459 — 462 : a correction of two errors in the descrip- 

 tion. — My absence from this island prevented my seeing the 

 article introduced in p. 459., relating to a species of Phyllo- 

 soma, taken on this coast; consequently I could not answer
