OLIGOCHATA OF TROPICAL EASTERN AFRICA. 203 
I received from him a very large number of Oligocheta 
belonging to thirteen species at least; of these I describe eight 
in the present paper as new. The eight new species are the 
following : 
Eudriloides Cotterilli, n. sp. 
Eudriloides brunneus, n. sp. 
Polytoreutus violaceus, n. sp. 
Polytoreutus Finni, n. sp. 
Polytoreutus kilindinensis, n. sp. 
Pareudrilus stagnalis, n. gen., n. sp. 
Gordiodrilus zanzibaricus, n. sp. 
Alluroides Pordagei, n. sp. 
In addition to these there were numerous examples in the 
collection of species apparently identical with Michaelsen’s 
Stuhlmannia variabilis. This species is indeed to all 
appearance the most abundant form of Eudrilid in the regions 
visited by Mr. Finn. Besides the specimens preserved by Mr. 
Finn, he brought me a large number of living Oligocheta ; 
the bulk of these were of this species. 
Another species abundant in the gatherings was a Ben- 
hamia of small size, which I have not minutely studied as it 
showed no noteworthy differences from the smaller species 
described by Michaelsen. 
In the mud from swamps brought home there was an abun- 
dant supply of a Dero with two long processes in addition to 
the four “ gills;” this species seems to be identical with that 
named Dero Miilleri by Bousfield ; in the same mud I found 
a Nais and an Enchytreid, neither of which have I identified ; 
these two species, however, were immature, and they did not 
exhibit any characters of particular interest. 
The worms were all of them, with the exception of the species 
of Kudriloides, the Benhamia, and the Polytoreutus, 
found in, or at the margin of swamps. The aquatic character 
of these Eudrilids is perhaps to be noted in connection with 
the total absence of dorsal pores, a character already known to 
distinguish the Eudrilide from the majority of “ earthworms.” 
The other forms were collected in soil outside a bungalow,
