NOTES AND DESCRIPTIONS OF SOME PARASITIC 
HELMINTHS COLLECTED BY THE BXPEDIMION 
By J. H. SANDGROUND 
THE following paper, constituting part of the report on the parasite collection, 
contains a description of a new species of the trematode genus Dicrocoelium, 
from the liver of a monkey, a new genus of the nematode family Strongylidae, 
also from a monkey, and a new species of the trichostrongylid genus Oswaldocruzia 
from a lizard. Nematodirus hopkeni (Leiper 1907) from the hippopotamus was 
well represented in this collection, and as a result of the reéxamination of this 
parasite it is considered necessary to remove it from the genus Nematodirus 
and to create a new genus for its reception.! 
Other new worms, the descriptions of which are published here for the first 
time, are: — Oxyspirura elani from a kite and a larval spirurid, which we have 
named Agamospirura liberiae, from tumor-like cysts of the intestine of a mon- 
goose. In addition to the above there are included more extensive descriptions 
of Anoplocephala gorillae, the only tapeworm known from the gorilla, and 
Cylicospirura subaequalis from the lon, of which previous descriptions are in- 
sufficient or incomplete. Notes and comments made incidental to our identifica- 
tions of such forms as Cysticercus pisiformis, Streptopharagus pigmentatus, etc., 
that may be of taxonomic interest have also been added. 
As a matter of record, a list is appended of parasites present in the collection 
which could be identified generically, and in some instances specifically, with the 
material available. 
An asterisk denotes a new host record of a previously described species of 
parasite.
