REPORT UPON TWO SMALL COLLECTIONS OF PENTA- 
STOMIDS WITH THE DESCRIPTION OF A NEW 
SPECIES OF POROCEPHALUS.

in Zoology in the University. 
(With Plate XX.) 
Through the kindness of Mr Nelson Annandale, Director of the 
Indian Museum, I have recently had the opportunity of examining a 
small collection of Pentastomids from that Museum. The collection 
contains one new species of Porocephalus and affords examples of new 
hosts and new localities in which species already known have been found. 
In all there were four different species. 
(i) LINGUATULA SUBTRIQUETRA, Diesing. 
This species lives in the lungs of crocodiles and at times wanders 
into the trachea and pharynx. Diesing described it from Caiman 
sclerops (Hoffmann calls it Alligator sclerops ), the alligator which has 
the widest range of all the genus in America. It extends from Southern 
Mexico to Northern Argentina. As far as I am aware, L. subtriquetra 
has not hitherto been recorded from the Eastern Hemisphere, but the 
specimen in the Indian Museum was taken from the “pharynx of a 
crocodile ” captured at Saugor on the mouth of the river Hooghly. 
This species has never been adequately illustrated so I have added some 
figures which, owing to the skill of Mr E. Wilson, justly represent 
the characteristic appearance of this Pentastomid. These figures 
(PI. XX, figs. 1, 2 and 3) show that there are four papillae in front of 
the mouth and two behind it, and emphasize the importance of the 
lateral Haps or flanges.
