Buds of first and second orders. Remarks and distribution When fixed, the pigments fade and B. magnicoecus becomes similar in appearance to B. gregalis. The number of stigmata rows and the body shape are similar. The species only differ in the shape of their stomach and the caecum. This is probably why Hartmeyer (1912) considered this a variety of his Botrylloides nigrum, which, in our opinion, is Botryllus gr

Buds of first and second orders. Remarks and distribution When fixed, the pigments fade and B. magnicoecus becomes similar in appearance to B. gregalis. The number of stigmata rows and the body shape are similar. The species only differ in the shape of their stomach and the caecum. This is probably why Hartmeyer (1912) considered this a variety of his Botrylloides nigrum, which, in our opinion, is Botryllus gregalis (see p. 74). The name B. magnicoecus has been used worldwide for all species having a large caecum. Michaelsen (1923Z?) recorded this species in Portugal, the Red Sea, and Hong Kong. Hartmeyer & Michaelsen (1928) increased the confusion when they included the Australian B. anceps as a synonym. The geographic distribution of B. magnicoecus in South Africa seems to be limited to the coast from Namibia to KwaZulu-Natal. All specimens recorded from other parts of the world, viz. the Mediterranean Sea, Portugal, Caraibes, Australia and Japan, belong to other species.
