ZOOLOGY 363 
On most of the well forested hills the Land Crabs of the genus Thelphusa are 
common. 
It is well known that the water mollusca of Tanganyika exhibit some 
resemblance to marine forms ; it is also stated that shrimps and sponges are 
found in this lake and Medusce. Mr. J. Moore, who was dispatched to 
Tanganyika by the Royal Society to thoroughly examine its marine fauna 
will probably, ere this book is published, have described his discoveries and 
enunciated his theories in this respect. 1

NOTES ON A COLLECTION OF 
LAND AND FRESH WATER SHELLS FROM ZOMBA 
By EDGAR A. SMITH. 
This collection was made by Mr. A. Whyte on the Zomba plateau at an elevation 
of 500 feet and upon Chiradzulu Mountain and its slopes during July and August, 
1895. It was presented to the British Museum by Sir Harry Johnston. The 
species are not very numerous, about thirty altogether, but probably half of them 
1 There would seem to be, however, from the collections of shells we have sent home from Lakes 
Mweru, Tanganyika, and Nyasa, a certain similarity in the types, so that Lake Tanganyika does not stand 
quite alone in the possession of a peculiar fauna. In the Appendices I give a list of the land and water 
Mollusca collected by us.
