BAL^NOPTERID^. 



Soc' 1840, p. 11, are evidently from the same animal, but there are 

 some discrepancies between them. Mr. Sweeting says, breadth 

 21 feet ; Mr. Yarrell says, girth 21 feet. Mr. Sweeting, total weight 

 25 tons ; Mr. Yarrell, probable weight between 20 and 25 tons. 

 Mr. Sweeting, length of skeleton 41, and head 11 feet ; Mr. Yarrell, 

 40, and head 10 feet. Mr. Sweeting says, " For the discrepancy as 

 to the number of vertebrse, &c., I am of opinion that this species 

 has not been described before, and I have proposed for it the name 

 Balcmoptera temdrostris " (Mag. Nat. Hist. 24th March, 1840, 342). 



The skeleton here described was sold, about sixteen j-ears ago 

 (1859), for five pounds, to Mr. Freane, and it was stated to have 

 been sent to London as a present to the British Museum, but it has 

 never been received, and I cannot find any further account of it ; 

 probably it was sold for manure. B. temdrostris is the earliest name 

 given specially to this species, but it cannot be used for a whale 

 with a broad nose or beak. This is most likely the same as the 

 " Ostend "Whale," or a nearly allied species. The dorsal fin is 

 described as small, conical, and three-fourths the length from the 

 nose. 



*** Dorsal Jin unknown. First rib ehnffcite, dilated at sternal end.

First rib of Sibbaldius Schlegelii ?, in Mus. Roy. Coll. Surgeons. 



There is the first rib of a whale of this genus in the Museum of the 

 Royal College of Surgeons, which, if it is not this, would seem to in- 

 dicate a fourth species. The origin of i.he specimen is unknown.
