^JJalcemi cisaniica, sp. n., Cope, Proc. Acad. Nat. Sc. Pliilad. 18G5, p. 168, 
the Black Whale of the whalers of the Atlantic coasts of the United States, 
referred to Euhalcena (Gray). Some additional notes on remains of whales, 
ibid. p. 180. 
Balcena aleoutiensis has been indicated as a probably new species, by Van 
Beneden, Bull. Acad. Sc. Belg*. 1865, xx. p. 853 3 found in the North Pacific, 
between 40° and 60° lat. N. 
Megaptera. Prof, van Beneden has examined and described the skeleton 
of the Borq^ual of the Cape of Good Hope in the Paris Museum {M. poeskop'), 
confirming Dr. Gray’s opinion that it is specifically distinct from the arctic 
M. longhnana. Bull. Acad. Sc. Lettr. etc. Belg. xviii. 1864, pp. 389-400^ 
with woodcuts.

p. 178, from the coast of Maine, U.S. 
^ JPhysalus antiquoru?n. Dr. Murie has published a description of a speci- 
men, 60 feet long, captured in the Thames in May 1859. After having 
described its external appearance and internal anatomy, he gives a very 
detailed account of the skeleton. Proc. Zool. Soc. 1865, pp. 206-227. Mr. 
^ Flower has published his observations on an adult male specimen stranded 
in Pevensey Bay, Sussex. He took particular care to preserve the pelvic 
bones ^to which, in this species, a cartilaginous appendage is attached, a 
rudimental representative of the hind leg ; and also directs attention to some 
well-developed muscles on the inner side of the forearm, between radius 
and ulna, ending in strong tendons passing to the palmar surface of the hand. 
Proc. Zool. Soc. 1865, pp. 699-705. 
Physalus sibbaldii (Gray). Mr. Flower has found that his Ph. latirostris 
(Proc. Zool. Soc. 1864, p. 410) is identical with this species. Having 
examined the two typical specimens ho points out in which points they 
agree with each other and differ from Ph. antiquorum. This species has 64 
vertebrie, and the baleen of a deep-black colour. Proc. Zool. Soc. 1865, 
p. 472. 
Physalus. A new species of Whale from the mouth of the Bio Plata is 
described by Dr. Burmeister in a letter to Dr. Gray, under the name of Palce^ 
noptera patachonica. Dr. Gray refers it to Physalus. Proc. Zool. Soc. 1865, 
p. 190, with woodcuts, representing osteological details. 
4 Sibbaldius antarcticus has been described as a new species by Dr. Burmeister 
from a bladebone, the only part examined ; it was foimd south of Buenos 
Ayres. Proc. Zool. Soc. 1865, p. 713. 
\Palcenoptera swmhoii, sp. 11 ., Gray, Ann. & Mag. Nat. Hist. 1865, xvi. 
p. 148 'j and Proc. Zool. Soc. 1865, p. 725, from the Island of Formosa. 
^ Balcenoptera robusta (Lilljeb.). Dr. Gray has added this species to the 
British fauna, recognizing it in a cervical vertebra (fourth or fifth) found on 
the coast of Devonshire. This vertebra is distinguished by the great width 
of the canal of the spinal marrow, which is greater ‘than the width of the 
body of the vertebra, and by the regular and well-developed form of its 
lateral processes. The species is therefore considered to be the type of a 
distinct genus, Eschrichtius, Proc. Zool. Soc. 1865, pp. 40-43, with a wood- 
cut.
