TUNICATA 



The Tunicates of the Cornish seas are usually abundant both in numbers and species, but the 

 impossibility of identifying the majority of them greatly restricts the dimensions of the accom- 

 panying list. Several very common compound ascidians in Falmouth Bay are known at Truro 

 only by the names the students have invented. Fortunately the compound ascidians collected by 

 Dr. Cocks in the neighbourhood of Falmouth were named by Milne-Edwards, otherwise the list 

 would have been a great deal smaller than it is. The classification and nomenclature followed is 

 that of Herdman in 'A revised Classification of the Tunicates' (Tram. Linn. Sac. 1891).

n. unc. locally around Falmouth and in trawl
