the mediastinal, scapular, and externomedian veins are all 
united, or there are two lines of union, one between the med- 
iastinal and scapular, and the other between the externomed- 
ian and internomedian veins. There are fifty species (28 sp. 
nov.) figured and described in detail. These are referred to 
seventeen species, four of which are new. 
Lydekker's Fauna of the Karnul Caves.' — This 
quarto, of 57 pages and 5 plates, belongs to the series of Pa- 
lasontologia Indica. The author describes remains of 42 mam- 
mals, 8 birds, 5 reptiles, i toad, and 9 mollusks. Of the larger 
mammals no complete skulls were found ; only detached teeth, 
fragments of jaws, and more or less imperfect limb bones. Of 
the smaller mammals skulls were found in some instances. 
The remarkable feature in the mammalian remains is the oc- 
currence of a Cynocephalus, which may be identical with a 
living African species; of HycBna crocuta ; of a smaH'equus, in- 
distinguishable from E, asinus; and of a Manis, apparently 
identical with the existing West African species, M. gigantea. 
The author considers the occurrence of these forms extremely 
important in supplementing the evidence afforded by the Si- 
walik fauna as to the probable derivation of many of the 
existing Ethiopian mammals from those of the later tertiaries 
of India. 
Branner's Cretaceous and Tertiary Geology of 
THE Sergipe-Alagoas Basin OF BRAZIL.' — The author 
states that the importance of this region is due to (i) The rep- 
resentation of a geological range unusual in Brazil : (2) The 
rich fossiliferous nature of many of its beds ; (3) The accessi- 
bility of good exposure across the entire section. He is of 
the opinion that the key to future successful geologic work in 
Brazil lies in the careful study and comprehension of some 
such typical region as that comprised in the provinces of Ser- 
gipe and Alagoas. Although much of this paper is of a sta- 
tistical nature, it will be found extremely interesting by the 
general reader as well as by the special student.
