This report completes the account of the Crustacea from Dr. Annandale's tour 
in the Far East, submitted to me for examination. It includes notes and descrip- 
tions of the Amphipoda collected in China and Japan, some terrestrial Amphipoda 
from the Botanical Gardens at Singapore, and an additional Jsopod which I dis- 
covered in one of the tubes of Amphipoda. 
The list of species dealt with is as follows : — • 
ISOPODA. 
Cyathura carinata (Kroyer). China. 
Amphipoda. 
Monoculodes limnophilus , n. sp. China. 
Atyloides japonica, n. sp. Japan. 
Gammarus annandalei, n. sp. China, Japan. 
Gammarus pulex (Linn). Japan. 
Talorches ia japonica, n. sp. Japan. 
Talorchestia malayensis, n. sp. Singapore. 
Grandidierella megnae (Giles). China. 
The collection dealt with here supports in the main the conclusions drawn 
from the study of the Mysidacea and Isopoda. 
The Tai-Hu, though a freshwater lake, has a very marked marine element in 
its fauna. This marine element has been derived from two sources : an immigration 
from the south, and one from the north. 
The southern element is representated among the Amphipoda by Grandidierella 
megnae, a species found also in the Ganges Delta, L. Chilka and Madagascar. The 
genus is known only from Madagascar, India, and now China, and the fact that 
the same species is found to inhabit the Ganges Delta and the Tai-Hu is almost if 
not completely paralleled among the Isopoda, for Tachaea spongillicola from the 
Ganges is remarkably close to, if not identical with Tachaea chinensis from China. 
The northern element in the marine fauna of the Tai-hu is much more marked
