cies ; it was CO feet long. The upper part, and pectoral fin, 

 are represented as black with gray reflections, and beneath 

 white, Lacepi'de, /. C & 7 ; and Cuvier, Oss. Foss. t. 2G, 

 /". 5, represents the head of this specimen. 



M. Companyo described the animal as deep siatc-gray, 

 the throat and lateral part of the pectoral fin glistening 

 white. Vertebroe 60, the 15 lumbar are very large. The 

 skeleton was at Lyons in 1835. 



From the form of the first vertebra; in the figure, I am 

 inclined to believe that Knox's Great Rorqual belongs to 

 this species. 



The colour of Albert and Rudolphis specimen is not 

 stated, but they differ from Hunter's and Knox's account 

 of the B. rostrata, in having 34 & 35 lumbar and caudal 

 vertebra;. Professor Eschricht considers Albert's specimen 

 the same as Hunter's. I have in the text (p. 20), re- 

 garded Rudolphi's specimen as the type of a species 

 which I have called B. laticeps. It may be only a syuo- 

 nyma of B. rostrata, but the skeleton requires to be com- 

 pared.

Lesson, {Tab. Reg. Anim. i. 202), gives the name of 

 Balcenoptera australis, to the " Fin-back of the Whalers 

 of the South Sea." It is not possible to know if he intends 

 this species or the Megapleron Poeskop. 



There has lately been imported from New Zealand a 

 quantity of finner-fins which are all yellowish white ; this 

 doubtless indicates a different species, which may be called 

 Balmnoptera antarctica. I have also received from Mr. 

 Smith, specimens of what is called in trade Bahai Finner. 

 This Baleen is black, the fibres on the edge of the larger 

 fins are purplish brown, and of the smaller or terminal 

 ones paler brown. They are 35 inches long by ll^- inches 

 wide ; and the smaller, 10 inches long, and 4 inches wide 

 at the base. This is so different in appearance fi-om the 

 other Baleen of this genus, that I propose to call it Bal<B- 

 noptera Brasiliensis. 



Megapteron. 



Professor Eschricht, in the Danish Transactions, has 

 given another figure of this species, and a very detailed 

 account of its anatomy and development, greatly founded 

 on the examination of the foetus. 



He considers it as the B. Boops of O. Fabricius. It is 

 the most common Greenland Whale, and, he believes, the 

 Bermuda Whale is the same species, and that it migrates 

 from Greenland to Bermuda, according to the season ; and 

 he cannot find any sufficient distinction in the skeleton of 

 the Cape specimen in the Paris Museum, to separate it as 

 a species from the Greenland examples. 



In the Paper that Professor Eschricht has in the press, 

 he has figured the dorsal fin of this genus, and shows that 

 it is more properly a bunch, as Dudley calls it, than a fin. 



The first rib is forked at the end near the vertebra. 



Brandt, in the list of Altaian animals [Voy. Alt. Orient. 

 1845, 4to), has adopted this opinion, and formed a sec- 

 tion for BaUciioptera longimana, which he calls Boops, 

 merely characterized as " Pectoral elongate." 



The foetal specimens exhibit numerous rudimentary 

 teeth in both jaws. These are figured by Eschricht, 

 Danish Trans, iv. t. 4,/. a, b, from specimens, 35 and 45 

 inches long.
