CKTACEA. 65 



and Natural History of the Cetacca " in the Journal of the Linnean 

 Society, vol. iii. p. (i'S. 



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

 pansion of his brother's essays, with a comiiiled 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 S2)e}-m. Whale (p. 475), but at length gives up 

 the subject. He has foiuid out that the Uumphacked Whale is 

 evidently a Rorqual (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 Balana Fhijsalus. He 

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

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

 (ji. 352). 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 

 beyoud the facts before him. 



Sir William Jardine's Whales, in the ' Naturalist's Library,' is 

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

 tracts from Knox and other English writers on the subject. 



Eschricht, in his 'Nordischcn WaUthiere,'p. 7, di^-ides the Cetacca 

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



1. SarkophcKjen : Orca. 



2. Teuthophagen : Physeter, EhjTichocete (Hyperoodontina, 



Grail), Monodon, Beluga, Globiceps. 



3. Ichthi/op)haf/eu : Phocaena, Delphinus, Platanista, and Ogmo- 



balasna, Eschricht, = Balffinoj^tera. 



4. Pteropodojihar/en : Leiobalasna, Eschricht, = Batena. 



He further proposes to separate these groups into Zahnwalle (or 

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

 except Ogmobald'iia ; this genus he places with Leiohalcena in the 

 second gToup, which he calls Bartenwcdle, which is synonymoiis with 

 Bala'na 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 Fin-Avhale {Bcdcvnoptera rostrata), 

 the Naebhval {Hjiperooilon), and the Nordhval (Bcdmia Mysticetus), 

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

 on the osteology of the latter species. 



Dr. Ludovicus Ileichenbach, in his ' SjTiopsis MammaHum Iconibus 

 illustrata ' (8vo, Leipsic, 1855), di\-ides the Whales into four families 

 and seven genera, thus : — I. Bala;nina. 1. Balcena. II. Narwalina. 

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

 natina. 5. Rytina ; (J. Hulicore ; 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 genci-ale des Peches ancienncs 

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

 remaining in MS. in the libraiT of the late Baron Cuvicr.
