sumably the Amblotheriidce) are provisionally referred to the Inseetioora.

Classification of the Mesozoic Mammalia. P. Ac. Philad. 1888, 
pp. 292-301. 
This paper is supplemental to the preceding, and makes considerable 
amendments thereon. The chief amendments are as follows, viz. : — A 
reconsideration of the dentition of Amyhilestes, Amphitylus , and Phasco- 
lotherium , in which it is shown that the latter probably had premolars. 
The identity of Leptocladus with Peramus ; and probably that of Pera- 
lestes with Spalacotherium. It is further considered that Peraspalax, 
Amblotherium, Achyrodon , Phascolestes, Stylodon, Stylacodon> and Kurtodon 
are closely allied, and represent at most two or three generic types, thus 
leading to the abolition of the families Kurtodontidce and Amblotheriidce , 
and the close identity of forms referred above to the two suborders 
Prodidelphia and Inseetioora Primitiva. Amphilestes , Phascolotherium , 
Triconodon , and probably Amphitylus have a triconodont, and all the 
others a tritubercular dentition. 
. A review of Mr. Lydokker’s Arrangement of the Mesozoic Mam- 
malia. Am. Nat. xxii, pp. 232-235. 
Criticizes the arrangement adopted in part of the British Museum 
Catalogue of Fossil Mammals [Zool. Rec. xxiv, Mamm. p. 10]. Concludes 
that the Multituber culata are not Diprodonts. Points out certain errors 
and misdeterminations.

The first instalment of a paper in which six Marsupials are described, 
of which two are new. [See Phalcingeridce and Dasyuridce.'] 
Stirling, E. C. A New Australian Mammal. Nature, xxxviii, pp. 588 
& 589. Reprinted in Zool. (3) xii, pp. 424 & 425. 
Describes a small mole-like Mammal from Australia. It is described as 
being burrowing, with a marsupium, but no epipubic bones. The teeth 
are compared to the figures of those of Amphitherium.

Collection of the British Museum. Loudon : 8vo, pp. xiv & 402,

“ This volume contains the descriptions of 151 species of Marsupials, 
and 3 of Monotremata , in addition to 12 recognizable varieties of the 
former and 2 of the latter, making a total of 1G8 definable forms.” Two 
new specific and two new generic terms are proposed, one of the latter 
being to replace a preoccupied name. Figures of the external form of 
several species recently described by the author are given, as well as those 
of the skulls, dentition, muzzles, feet,&c., of numerous types. [See Phas- 
colomyiclce, Phalanyeridce t Macropod idee, Peramelidie , Dasyuridce , and 
Didelphyidce.~\
