II. MAMMALIA. 
INTRODUCTION. 
The event of the year, so far as Mammals are concerned, is the dis- 
covery, in South America, of a living representative ( Cccnolestes ) of the 
Epanorthidui , hitherto known only from the Tertiaries of Patagonia. 
Tiiomas — to whom we are indebted for this advance in knowledge — also 
contributes a large number of other papers, dealing, as usual, with 
Mammals from all parts of the world. His joint work with Sclater 
on Antelopes is continued. Important work on the smaller Mammals of 
North America — more especially the Shrews and certain groups of 
Rodents— has been published during the year; Allen, Bailey, Bangs, 
Merriam, Miller, and Rhoads being the chief contributors to this 
branch of the subject. An increasing tendency to the multiplication of 
genera, species, and subspecies may here be noticed. Among other 
monographic work, reference may be made to Lahille’s revision of the 
Argentine Armadillos ; while Moreno’s memoir on the Cetaceans of the 
same district is both descriptive and faunistic in its scope. In connec- 
tion with Cetaceans, the Prinoe of Monaco’s discovery that the food 
of the Sperm )Vhalo consists of huge polagic Cophalopods, is full of 
intorost. From a morphological point of viow, the first part of G Old- 
berg & Nansen's memoir on the development of the same group (which 
should have been included in the last Record) is of the highest import- 
ance ; as are the observations of the former, and also of Kukenthal on 
the vestiges of hind limbs in foetal Whales. 
In Australia considerable attention has been directed to the develop- 
ment aud structure of Ornithorhynchus, by Hill, Martin, Tidswell, 
and Wilson. 
The so-called Pithecanthrojms has been a fruitful subject of discussion, 
and the general concensus of opinion inclines to the view that the 
remains cannot in any way be regarded as indicating a real “ missing 
link.” 
In distribution, Greve’s memoir on the Carnivora is likely to prove 
of the highest value ; while Matschie’s work on the Mammalian fauna 
of German East Africa, as well as that of Momus, are likewise note- 
worthy. Many other minor faunistic papers will be found in the 
sequel. 
In dentition, Leciie’s elaborate memoir cannot fail to attract attention ; 
and among papers on anatomy notice may be directed to Beddard’s 
study of the brain of Lemurs and other forms, and Smith’s description 
of that of Notoryctes. 
Turning to extinct forms, the memoirs of Winge on the Primates and 
Carnivora of Lagoa Santa deserve especial mention, on account of their 
including a new classification of the two orders. In the Argentine, 
Amegiiino, Mercerat, and Roth have continued their investigations of 
the Tertiary faunas of Argentina proper and Patagonia ; and in the 
papers of the two former it is noteworthy that the flow of new generic
