On two subfossil Whales discovered in Sweden.

according- to the drawings kindly communicated to us by Dr Flower, they 

 have in the Hunterius Temminckii. In the latter it is farther removed from 

 the caput and has the form of a projecting acute angle, and is not trun- 

 cated at the point. In the species before us the distance between the a- 

 cromion and the cavitas glenoidalis is small, and accordingly the collum 

 scapulae very short. The form of the bladebone exhibits a general agre- 

 ment with that of the Balaenidae, and its breadth at the upper part is not 

 so much greater than its length. It is however at the upper edge thicker 

 than usual, but that is doubtless a consequence of the animals tender age, 

 especially as that edge is irregular and spongy, so that the bone has evi- 

 dently had a great cartilaginous continuation. Both the anterior and posterior 

 borders are concave. On the outer side it is somewhat concave with ra- 

 dial, broken furrows. From the acromion the spina scapulae extends so 

 far upwards, that it is discernible above the middle of the bone. The ca- 

 put, viewed endwise (fig. 113), is of an oval form, hollowed out in the 

 middle, with an acute angle in front and rounded off behind, with a scar- 

 cely perceptible obtuse angle there. Its outer border is somewhat more 

 convex than the inner. Dimensions: Breadth at upper part V 3f"; length 

 1' 2"; breadth above base of acromion 5J-"; d:o of collum 4-|"; length of 

 acromion If"; thickness of upper border of bladebone 1". 



ADDITION. 



Since the above was written three bones of the imperfect whale- 

 skeleton last described, of the Hunterius Svedenborgii , have been reco- 

 vered by Professor F. Sundewall, of this University, and presented to 

 the University's Zoological Museum. These bones are: one caudal vertebra, 

 right bladebone and part of a rib. As they are perfectly similar to those above 

 described, they do not contribute any addition to our knowledge of this 

 Whale, but they afford some confirmation of the views we have taken. 



The vertebra has evidently occupied a place between the 3 rd and 4 th 

 of those above described, and is accordingly, according the probable cal- 

 culation there made, the 7 th caudal vertebra, which was there said to be 

 missing. Its lateral processes are less than those of the 6 th , but longer 

 and slenderer than those of the 8 th . The processus spinosus and processus 

 mammillares agree entirely with those of the last-mentioned, and the foramen 

 spinale is lower than in the 6 th , but a little larger than in the 8*. The arti-
