Taschkend. 
A. Agassiz has announced (Am. Natur. vi. p. 636) the startling discovery

Polystomum oeellatum, the little-known parasite from the pharynx of Emys

Temnocephala chilensis, Gay, has been rediscovered in Luzon and Mindanao 
on difierent species of freshwater crabs by Semper, who (3) gives an account 
of its anatomy, correcting and supplementing Philippi’s. There is no meta-

agreeing in shape with the adult.
