Few terrestrial planarians are as yet known to occur in the 
islands remote from continental land in the Indian Ocean. 
Such are Pelmatoplana mahéensis von Graff and P. 
braueri von Graff (12, 20) from the Seychelles, Placo - 
cephalus isabellinus Geba (11) from Mauritius, Geo - 
plana whartoni Gulliver (1) from Rodrigues, and 
Rhynchodemus ceylonicus von Graff (17) from Male 
Atoll. 
The material serving as a basis of the present report was 
collected by Mr. H. P. Thomasset in October, 1918, in the island 
of Mauritius, and by Mr. H. J. Snell in November and December 
of the same year in the island of Rodrigues. The specimens 
were sent to Professor J. S. Gardiner, who kindly turned them 
over to me for examination. 
In this communication it may not be out of place to add 
a brief account of G. whartoni Gulliver, known as occurring 
in the Rodrigues Island. I am much indebted to.the Director 
of the British Museum of Natural History for the privilege of 
studying this species. 
The following is a list of the species dealt with in the present 
paper : 
Geoplana whartoni Gulliver ; 
Placocephalus isabellinus Geba: 
Rhynchodemus ceylonicus von Graff: 
Amblyplana trifuscolineata, n. sp.
