NOTES ON PARASITES. 



By a. E. Shipley, M.A., F.R.S., Felloiv and Tutor of Christ's College, Cambridge, 

 and University Lecturer on the Morphology of the Invertebrata. 



Mr Stanley Gardiner's expedition had as its object the exploration of coral-reefs and 

 was not concerned with parasites, nevertheless a few specimens were collected, and amongst 

 these were some cysts from Chelone mydas Cuv. and from Varanus bengalensis Daud. which 

 seem to be pathological rather than helminthological in character. These have been sent to 

 the Cancer Research Laboratory, Victoria Embankment, which at present is anxious to obtain 

 specimens of 'growths' in the lower vertebrata. 



TREMATODA. 



AMPHISTOMUM SPINULOSUM Looss.

Four or five specimens were taken from the alimentary canal of the Green Turtle, 

 Chelone mydas Cuv., killed at Minikoi. They were found living just where the small passes 

 into the large intestine. 



NEMATODA. 



PHYSALOPTERA VARANI, Parona. 



Parona. Ann. Mus. Genova, Ser. ii. vil. 1899, p. 776. 



This parasite was first described by Prof Parona from Varanus bengalensis Daud., a 

 scavenging lizard from Palon (Pegu). Mr Gardiner's numerous specimens were taken from 

 the same species captured at Weligama, Ceylon. Some of them were fixed by their ends 

 in the valleys between the rugae of the stomach walls, but the larger forms, the females, 

 were free. I am indebted to Dr von Linstow for the identification of these specimens.
