small portion of the belly. The skull is proportionally smaller than 

 in the Greenland Right Whale, much higher and broader behind. 

 The muzzle viewed from above bulges at the sides. The frontal 

 bone and the hindmost excrescence of the upper jaw are not oblique 

 from behind, but (at least in matui'ity) laterally flattened; finally, 

 the lower jaw is much more powerful. 



" Our skeleton has seven vertebra3 in the neck, of which the first 

 four are soldered together, and only the second and third have lateral 

 processes beneath. There are 15 pairs of ribs, of which only those 

 nearest the middle, viz. the third to the seventh, are provided with a 

 small crown ; they do not, however, reach the vertebrae of the body. 



" The fii'st rib is unusually broadly and deeply inserted into the 

 end of the sternum, or running straight out into two processes, and 

 divided at the vertebral ends by a deep notch into two knobs, it is 

 fastened to the lateral processes of the first and second vertebrae. 

 There are onlj^ 10 dorsal vertebrae, 8 lumbar, and 24 caudal. The 

 flipper has five well- articulated digital and clearly developed meta- 

 carpal bones." — Schlegel. Ahhandl. 1841, 37-

First rib of Himterius Temminckii, in the Leyden Museum. 

 (From a sketch by Mr. Gerrard.) 



Mr. Flower has given me a drawing of the ear-bone from the same 

 specimen : it is rhombic, very thick and swollen, like, but rather 

 wider than, the ear-bone of Euhalmia australis. 



" A very fine skull of an adult and a nearly complete skeleton of a 

 young incUvidual, both obtained from the Cape of Good Hope by 

 Dr. Horstock, are contained in the Leyden Museum. These are 

 briefly described by Schlegel in his ' Abhandlungen aus dem Gebiete 

 der Zoologie,' &c. (Leyden, 1841), part 1. p. 37. 



"The skull is 13' 5" in extreme length. To any one accustomed 

 to the appearance of the skuH of the adult B. Mysticetus, the dif- 

 ferential characters exhibited by this specimen are very striking. 

 The size is much inferior, both absolutely and as compared with that 

 of the body of the animal. Its general contour is less regularly 

 arched, as it rises abruptly in the occipital region to a very prominent 

 and rounded eminence at the junction of the supraoccipital, frontal, 

 and nasal bones, and then slopes gradually down to the apex of the 

 beak. The articular processes of the squamosals are broader and 

 less elongated. The supraorbital processes of the frontal are, as 

 noticed by Schlegel, directed more horizontally outwards, shorter,
