Some time ago Dr. Harmer entrusted me with a small 

 collection of Planarians made by Professor Haddon 

 whilst in the neighbourhood of the Torres Straits during- 

 the year 1889. Shortly afterwards Dr. Gardiner kindly 

 permitted me to describe his fine collection from the 

 Maldives and Laccadives, and with them a few specimens 

 from Rotuma and Funafuti, in the Pacific. My account 

 of the Maldive and Laccadive material has already been 

 published [9] ; the Rotuma and Funafuti specimens, to- 

 gether with those from the Torres Straits, are described 

 in the present communication. 



But little is at present known ot the Planarian fauna 

 of tropical seas. Since the publication of Lang's 

 monograph of the Polycladida of the Gulf of Naples, 

 several important memoirs dealing with this group have 

 been published ; the greatest additions have been made 

 by Verrill for the coasts of New England [6] and by 

 von Plehn [4]. 



I have not been able to find any record of Polyclads 

 from Torres Straits. Dr. Collingwood, however, records 



Jatwary ijth, igoj.
