X. — Report on the Ttjebellama. By F. W. Gtamble, M.Sc. 



The Turbellaria have received scant notice at the hands of previous 

 fatinistic workers on the coasts of Ireland. It is, then, not surprising 

 that in the following list of seven Polyclads from Valencia, four species 

 are added to the Irish list : Stylochoplana macidata. Cycloporus papil- 

 losus, Oliyocladus sang?mioIe?itus, Stylostomum i-ariahile. 



The species of EhabdoccBles require considerable time and care for 

 their identification, and there is no doubt that many additional forms 

 may be found, especially among the Acoelous and Alloeocoelous groups. 



(«) POLYCLAMDA. 



stylochoplana maculata, Quatrefages. 



Not uncommon among brown weeds on the shore near Reena- 

 giveen, on Beginnis shore, and also dredged on the Ascidian 

 ground in the harboiu*. 



Leptoplana tremellaris (0. P. Miiller). 



Common everywhere under stones between tide-marks,^ 

 usually occurring in groups. 



Prostliecerseus vittatus (Montagu). 



The muddy shores of estuaries form the proper habitat of 

 this fine species. It is taken in the fine, muddy deposit that 

 accumulates in bivalve-shells dredged in the harboui', and on 

 the coralline -ground at Port Magee. 



Eurylepta cornuta (0. F. Miiller). 



Dredged on sponge-covered shells on the Ascidian ground 

 and Shell-beds of the harbour, and again among sponges in 

 Port Magee channel. 



Cycloporus papillosus, Lang. 



On compound Ascidians (chiefly Leptodinum and Botryllus) 

 from the shores of Murreagh Point, Glanleam Bay, and Church 

 Island. 



Oligocladus sanguinolentus (Quatrefages). 



Dredged on shells in the harbour.
