northern and colder latitudes. Malmgren, in Wiegm. Arch, 1864, p. 91 
(QEfvers. Svensk. Vetensk. Akad. Forhandl. 1864, p. 150). 
'^Beluga catodon (L.) or Beluga borealis (Less.). Prof. J. Wyman has 
examined and dissected a male specimen, which has been on public exhibition 
iu a water-tank for nearly two years. He descnbes the external characters, 
the dentition, parts of the skeleton, and the internal organs. As far as we 
know, this is the first instance of a Cetacean having been kept in captivity 
for any length of time ; and it is interesting to hear that it showed some 
capacity for education. The proprietor stated that this white Whale was less 
docile than the Delphinus tursio who was for a time a companion with him in 
the tank. The animalwas ten feet long. Bost.Journ. Nat. Hist, vii.p. 603,plM2.^ 
^ The Beluga is common on the coast of Spitsbergen and in the White Sea.

^ BhoccBna communis. Dr. Crisp has dissected a specimen, 3 feet long } the 
intestinal canal measured 66 feet 3 inches, and the brain weighed 16 ounces.

'4 Glohiocephalus. M, Van Beneden gives an account of a Cetacean throvm 
on shore near Antwerp the 27th of April 1864. He has identified it with 
Delphinus mclas (D. glolicops, Cuv. j Glohiocephalus svineval, Gray). As 
regards the occurrence of this species in the Mediterranean (see Gervais’s 
paper, p. 36), the author thinks it possible that the specimens observed on 
that coast should be referred to Delphinus feres (Bonnat.). Bull. Acad. Sc. 
etc. Belg. 1864, xvii. p. 4.39. 
'I Orca 7neridionalis, sp, n., Flower, Proc. Zool. Soc. 1864, p. 420, from Tas- 
mania. Two skulls in the collection of the College of Surgeons are extremely 
similar to that of Orca crassidens from the northern hemisphere. Therefore 
the species may probably enter Reinhardt’s genus Pseudorca. 
'^Lagenorhynchus leiicopleurus. Dr. Duguid has given an account of the 
capture of a shoal of this Dolphin in the Orkney Islands, and described its 
external characters. Ann. & Mag. Nat. Hist. 1864, xiv. p. 133, pi. 3. 
iMgenorhytickus aciitus. M. Poelman describes and figures a specimen 
caught on the Belgian coast, under the name of Delphinus cschrichtii. The 
skeleton also is described. Bull. Acad. Sc. etc. Belg. 1864, xvii. p. 604. 
^Delphinus delphis. An immense shoal has been observed in the Westfjord 
on the coast of Norway by Malmgren, Wiegm. Arch. 1864, p, 88. 
'^Delphinus guianensis^ sp. n.. Van Benedei), M(Sm. Cour. Acad. Sc. Belg,

Halmatums parii Prof. Hyrtl describes the arteries, in Denkschr. Acad. 
Wiss. Wien, 1864, xxii. p. 158. 
Bchidna. Mr. Flower has examined the brain, and found the optic lobes 
not essentially difierent from those of more highly organized mammals, the 
^cs^esand nates being well developed, and separated into corpora quadrigemina 
by a longitudinal groove as well as by a transverse one. Proc. Zool. Soc. 
18()1, p. 18. 3\vo views of the brain are given, one from above, and the 
other from the side.
