MAMMALIA. 
Qlohiocephalus edwardsi not specifically distinct from O, molas. Skeleton 
noticed by Fischer, 1 . c, pp. 276-278. 
Orampus griseus^rissoanus. A detailed description of the examples cap- 
tured on the British coast is given by Prof. Flower in Trans. Zool. Soc. viii. 
1872, pp. 1-2X. He refers this Dolphin to the subgenus Grampus, which he 
characterizes in comparison with Olohiocephalus. PI. 1 represents the animal^ 
pi. 2 the skeleton. 
Ziphius. In a paper published in the Trans. Zool. Soc. viii. 
1872, pp. 203-234, Prof. Flower has collected ajl available in- 
formation with regard to these Cetaceans. He points out that 
there exist well-marked structural characteristics by which cer- 
tain small groups of species are differentiated from one another, 
viz. Ziphius, Hyper oodon, Mesoplodon, and Berardius, The ske- 
leton of B. arnouxi is fully described and figured on pis. 27-29. 
^ • — As regards Mesoplodon, Prof. Turner comes to the same con- 
clusion as Prof. Flower. Trans. R. Soc. Edinb. xxvi. 1872, 
p. 777. 
Ziphius cavirostris. Prof. Turner describes and figures the skull of an ex- 
ample from Shetland. Trajis. U. Soc. Edinb. xxvi. 1872, pp. 7fi0-770, pie. 20 
& 80 (part.). ^ 
Mesoplodon sowcrhii Prof. Turner describes and figures a skull in his 
museum, /. c. pp. 771-780, pis. 29 & 80 (part.) . 
MARSUPIALIA.

Genus Nototherium. Phil. Trans. 1872, jDp. 41-82.-^ 
Part VI. Genus Phascolomys. Ibid. pp. 173-196, pis. ll-r- 
23. [See Zool. Rec. viii. p. 21.]

i!:^hascolaretos cinereus. The Muscular Anatomy of the Koala,” by A. 
Macalister, 1. c. pp. 127-134. This animal presents, in its muscular system, a 
greater number of structural divergences from the general placental type thau, 
perhaps, any other Didelphian. 
^Phascolomys. The craniological characters of the living species compared 
with those of the extinct in Prof. Owen’s memoir noticed above. 
^ Phascolomys latifrons. Notes by A. Macalister, with figure of skull, P, Z. S.
