In the absence of auy specialists in these groups from the naturalists engaged 

 in the Clare Island Survey, it has fallen to our lot to summarize the available 

 records. That so large a number of Tunieates appears in the list is due to 

 Prof. Hartmeyer of Berlin, who is at present engaged in examining the 

 Tunicate material belonging to the Fisheries Branch of the Department of 

 Agriculture, and who kindly consented to furnish a preliminary account 

 of the collections from Blacksod Bay. There is still a good deal of 

 material, collected in Clew Bay and other parts of the district, awaiting 

 examination. 



TUNICATA. 



Appendiculariae. 



Oikopleura sp. — Specimens of Oikopleura are very common in tow-nettings 

 throughout the district, both in inshore gatherings and in the open sea. 

 It is probable that most, if not all, of these are 0. dioica, though they 

 have not been identified with certainty. 



Thaliaceae. 



Salpa fusiformis Cuv. — An oceanic species, frequently drifted into the 

 district.
