The following paper is an account of the results obtained by the study of 
Cestodes sent to this Department for identification. For the most part, the 
tapeworms were species with a wide distribution and with many previous 
records of their occurrence. Among them were several whose anatomy, well- 
known in many respects, had been inadequately described with regard to 
characters useful, if not essential, for identification. 
The present paper, with the exception of that portion concerning the new 
species Cotugnia fastigata, is an attempt to deal with such characters and so 
complete already existing descriptions. 
I wish here to express my indebtedness to Prof. Nuttall, F.R.S., for 
specimens of Hymenolepis columbae (Zed.), H. coronula (Duj.), H. gracilis 
(Zed.), and Cotugnia fastigata n. sp., collected by Dr H. H. Marshall at 
Rangoon, and to Dr C. L. Boulenger for those of Cotugnia digonophora (Pasq.), 
from Mesopotamia. 
COTUGNIA DIGONOPHORA (Pasquale, 1890). 
The genus Cotugnia was created by Diamare (1893) for those avian 
Cestodes which have a double set of male and female reproductive organs in 
each proglottis, and a rostellum armed with T-shaped hooks. The type 
species is C. digonophora (Pasq.), a form described under the name of Taenia 
digonophora by Pasquale in 1890 from chickens in Abyssinia. Since that date,
