ANIMAL PARASITIC INFECTIONS 423 
He has since carried on extensive studies in this country and in Europe with 
reference to the gorilla and has prepared a most excellent and valuable mono- 
graphic review of the genus Gorilla published during the preparation of this 
Report.! His article is summarized in Chapter XX XIII. 
The parasite from the gorilla proved to be a cestode and was turned over to 
Dr. Sandground upon our return for further study. About the time that he was 
completing his study of this material, a preliminary report was published by 
Nybelin* upon a cestode collected from a gorilla of the Kivu voleano region 
by the Swedish Central African Expedition. While Nybelin’s description is 
apparently not entirely complete, he has given this cestode the name of An- 
oplocephala gorillae. Sandground has made a careful study of the material 
from the gorilla shot by Mr. Coolidge and has given a more complete descrip- 
tion of the species (page 473). Apparently this parasite has not been observed 
before and Nybelin’s and Sandground’s descriptions of it are the first to be 
published. 
The parasite is particularly characterized by the absence of the rostrum and 
by the great width of the segments in comparison to the length. The genital 
pores are all on one side and the gonads present special characteristics. The 
parasite bears no close resemblance to the species of Bertiella, which Miss Cram ? 
recently reported from man and a chimpanzee in Cuba. Other species of the 
genus Anoplocephala (sensu stricto) have been found only in herbivora. 
Baer * has recently prepared a monograph upon the family Anoplocephalidae. 
He records that six species of Anoplocephala have been previously described. 
To the table which he gives in this monograph, the seventh species from Sand- 
ground’s description is here added.
