Extract

In previous papers (Millar, 1952; 1954a; 1954*0 I have dealt with the re-productive cycle of several ascidians in Scottish waters, and in the present account observations are extended to other species.

The course of breeding was studied in the following species. Family Polyclinidae:Sidnyum turbinatum Savigny, Aplidium nordmanni (Milne Edwards), A.punctum (Giard), A.pallidum (Verrill) and Polyclinum aurantium Milne Edwards. Family Didemnidae:Didemnum candidum Savigny and Lissoclinum argyllense Millar. Family Clavelinidae: Clavelina lepadiformis (Müller).
