Dr. MARLOTH exhibited a branch of the Euphorbia virosa, collected on 
the mountains near Prieska. The milky juice of the plant was one of 
the materials used by the Bushmen for their arrow-poison. 
Another exhibit from the same locality was a very pretty fungus. 
The mycelium covered the rocks close to deposits of feces of rock 
rabbits, and Dr. Marloth was of opinion that this fungus was parasitic 
on the exudations from these deposits. It was a new species—perhaps 
even a new genus.

Mr. PERINGUEY exhibited some examples of a nematod worm, a 
Mermis, spec. ignot., a new parasite of our migratory locust, Pachytilus 
nugratorius. 
These thread-like worms, it is daily asserted, destroy the locust in 
the body of which they undergo their development, some of the 
specimens -of locusts exhibited containing as many as four of these 
worms.
