Calcareous bodies are numerous, measuring 15*2/u in diameter. 
This species is distinguished from some of the species found in man 
by the following points: — 
T. africatta. — Segments always broader than long. 
T. confusa. — The gravid segments may be as long as 35 mm., 
but the width is only 5 mm., whereas in the present species, with a 
length of 32 mm. the width is 9 mm. 
T. saginata Gravid segments, 15 to 20, rarely 25 mm. long, 
4 to '/ mm. wide. 
T. solium. —Gravid segments, 10-12 long by 5 mm. broad. 
1 hope soon to be in a position to describe complete specimens of 
this worm; for the present I propose the name Taenia bremneri. 
The type segments are in the museum of the Liverpool School of 
Tropical Medicine. 
III. A NEW LINGUATULID 
( Porocephalus pattoni, n. sp.) 
Habitat: — This linguatulid occurs in the lungs of the Indian rat 
snake Zamenis v. Ptyas mucosus or Dhaman. 
Diagnosis :—Body greyish white (spirit specimens), showing a 
separation into head, neck and body. The head is globular and 
flattened ventrally and rounded dorsally, and is separated from the 
body by a fairly distinct narrow portion or neck. Of some dozen
