88 BAL^2s'IDiE. 



There is also the skeleton of the Scame foetus, prepared by Mr. Knox. 

 The bones of the head are ossified, and show the characters of the 

 genus ; that is, the upper jaw is high, arched, and its sides are only 

 slightly keeled, not depressed and expanded as in Balcenoptem, &c. 

 The jaws show the grooves for the teeth. The rest of the skeleton 

 is only cartilaginous. These specimens are described by Mr. Knox, 

 Cat. Anat. Prep. Whale, 21. 



There is the skeleton of a half-grown specimen, brought home by 

 M. Guerin, in the Anat. Mus. Univ. Edinb. (head 6 feet long ?). 



Mr. Knox gives some observations on the lactiferous glands of a 

 foetal specimen in the account of the dissection of a Balcena rostrata. 

 The foetus is also described by Roussel de Vauzeme, Ann. Sci, Nat. 

 Zool. 1834, ii. 125; L'Institut, 1833, i. 106, and 1834-, ii. 289; 

 Wyman, Proc. Boston Soc. N. H. 1850, iii. 355 (foetus). 



The embryo of a whale in spirit was presented to the Nat. Hist. 

 Soc. of Newcastle-upon-Tyne, in 1836, by J. Stevens, Esq. 



A foetal specimen is figured by Camper (Cetac. t. 1. f. 1, 2). It is 

 probably from a dried specimen, and the head is very slender. It is 

 to be observed that it is longer in proportion to the length of the body 

 than the very young specimen oi B. mistralis, 17 feet long, figured 

 by Delalande, Diet. Class. H. N. t. 140. f. 3. 



The Icelandei-s distinguish two kinds of "VVTiale, that of the North 

 (Nord Hvale) and that of the South. They say that the skin of the 

 latter has white calcareous crowns (CorowiJfe) which are not found in 

 the former. (See Van Beneden, Bull. Sci. Belg. 1860, xxii. 4G0.) 



Each species of Whale has its own peculiar kind of sessile Cirri- 

 pede; one has the Coronida, another the Diadema, and a third the 

 TnbicineUa. They are all sunk in the surface of the skin, with the 

 aperture for the free valve, or operculum as it is called, alone ex- 

 posed, and as they grow in size the deeper they sink into the skin. 

 Some genera aUied to Coronulce are found on the shells of turtles, 

 and on the outer surface of shells that are partially covei-ed by the 

 mantle of the animal. The Whales have also pedunculated Cirri- 

 pedes, as Otions, on them : these were early observed. " This Whale 

 hath natiu-aUy growing upon his backo white things hke unto Bar- 

 nacles " (Purchas, Pilgrims, 471). Coronida Bcdcenaris is found on 

 the Eight "V\Tiale of the Arctic Seas (see Pontoppidan, §§ 78, 81). 



Some observations on the osteology are given by Professor Owen 

 in Cat. Osteol. Mus. Coll. Surg. ii. 439 k 441. 



Professors D. E. Eschricht and J. Reinhardt, in " Om Nordhvalen, 

 Balcena i/?/s^iVf ft«," pubUshed separately in Copenhagen in 1861, and 

 in the fifth voliime of the Transactions of the Danish Royal Academy, 

 have given a very full account of the osteology of this animal and 

 its alUes in the North Sea. 



The male and female " Baleine franehe," figured by Duhamel, 

 Peches, ii. t. 1. f. 1, 2, and which are copied in the Svo edition of 

 Bloch, Fische, t. 1, seem like figui'es made from description by an 

 artist who had the figure of a Dolphin, or rather Grampus, in his 

 eve. The baleen is drawn as if it was attached to the lower jaw, 

 and projects from the mouth in front. The same figure, with a series
