CETACEA. 65 



and Natural History of the Cetacea " in the Journal of the linnean 

 Society, vol. iii. p. 63. 



M. F. Cuvier's 'C^taces' (Paris, 1836) is little more than an ex- 

 pansion of his brother's essays, -with a compiled account of the 

 species ; but he has consulted with greater attention the works of 

 Sibbald and Dudley, and has some doubts about the finned Cachalots 

 being the same as the Sperm Whale (p. 475), but at length gives up 

 the subject. He has found out that the Humphached Whale is 

 evidently a Borqual (p. 305), but does not record it as a species, nor 

 recognize it as the Cape Rorqual, nor as Dr. Johnston's Whale ; the 

 latter he incorrectly considers the same as Balwna Physalus. He 

 combines together as one species Quoy's short-finned Rorqual of the 

 Falkland Islands with Lalande's long-finned Whale of the Cape 

 (p. 355i). He is in great doubt about the hump of the Cachalots 

 (p. 279) ; his remarks on that subject and on the Cachalots of 

 Sibbald show how dangerous it is for a naturalist to speculate 

 beyond the facts before him. 



Sir WiUiam Jardine's "Whales, in the 'Naturalist's library,' is 

 chiefly an abridgement of M. Lesson's compilation, with some ex- 

 tracts from Knox and other English writers on the subject. 



Eschricht, in his ' Nordischen Wallthiere,' p. 7, divides the Cetacea 

 into four groups, according to their food, thus : — 



1. Sarlcophagen : Orca. 



2. Teuthophagen : Physeter, Ehynchocete (Hyperoodontina, 



Cfray), Monodon, Beluga, Globiceps. 



3. Ichthyophagen : Phocsena, Delphinus, Platanista, and Ogmo- 



balsena, Eschricht, = Balsenoptera. 



4. Pteropodophagen : Leiobalaena, Eschricht, = Balsena. 



He further proposes to separate these groups into Zahnwalle (or 

 Tooth- whales), which includes all the genera in the first three groups, 

 except Ogmohalcena ; this genus he places with Leiohalcena in the 

 second group, which he calls BartenwaUe, which is synonymous with 

 Balcena of Linne. 



Eschricht, in the ' Danish Transactions,' has published several most 

 interesting papers on the anatomy and development of the Whales of 

 the North Sea, especially of the Pin- whale (Balcenoptera rostrata), 

 the Naebhval {Hyperoodon), and the Nordhval (Balcena Mysticetus), 

 and with Professor J. Reinhardt he has published a complete treatise 

 on the osteology of the latter species. 



Dr. Ludovicus Eeichenbach, in his ' Synopsis MammaHum Iconibus 

 iUustrata ' (8vo, Leipsic, 1855), divides the Whales into four families 

 and seven genera, thus : — I. Balsenina. 1. Balcma. II. Narwalina. 

 2. Monodon. III. Delphinina. 3. Physeter ; 4. Delphinus. IV. Ma- 

 natina, 5. Rytina; Q. Halicore; 7. -Manatus. 



Mr. Edward Wakefield has given a very good chronological history 

 of Whales and Whaling in Simmonds's ' Colonial Magazine ' for July 

 1844, p. Ill ; he quotes the ' Histoire generale des Peehes anciennes 

 et modemes,' by S. B. Noel (vol. i. 1815), the rest of the work 

 remaining in MS. in the library of the late Baron Cuvier.
