Genus Galoncus, Railliet, 1918. 

 Galoncus perniciosus (v. Linstow, 1885) Railliet, 1918. 



The collection contains one female only of this species, collected from the intes- 

 tine of a leopard (Felis pardus) in the Zoological Gardens, Calcutta. 



We have nothing to add to the description given by Railliet beyond remarking 

 that the head is evidently retractile, and in the extended state the buccal capsule 

 appears relatively much larger in proportion to the width of the body of the worm. 

 The specimen figured by Railliet (1918) is in the retracted state. Doubtless the 

 powerful muscles attached to the lateral walls of the buccal capsule, which were 

 noticed by Railliet and other authors, are connected with the retraction of the 

 head.
