Until 1901 this Ascidian was comparatively rare, having only 

 been recorded occasionally from Millbay Ch., the Cattewater, 

 Yealm B., Mewstone Ledge, and tiie Eddystone Gds., and the 

 specimens were never of greater length than 4-5 inches. In that 

 year the species became for a time very abundant in Millbay Docks, 

 completely covering the piles and rafts, and many of the specimens 

 from the Inner Dock were of extremely large size, measuring as 

 much as a foot in length (e.j.a.): Stoke Pt. Gds., small specimens 

 fairly common (s.p.). 



Breeding: June-July (R.A.T.) : Aug.-Sept. (w.G.).
