1 1 unite under this species [Amaroucium variabile] a large number of specimens, collected in the neighbourhood 

 of Kerguelen Island, which present great variations in form, size, colour, and some other particulars. They are, how- 

 ever, all closely related to one another, and although it might be possible to break them up into two or three species, 

 I believe that the differences between the extreme forms are sufficiently bridged over by intermediate condition* t" 

 warrant one in regarding them as composing a single species only. They form an extremely interesting series on 

 account of the way in which they illustrate individual variation. — (Herdman, Zool. Chall. Exp., part ?>"!, p. 216.) 



2 Ascidia challengeri is a large and somewhat variable species, which appears to be common at Kerguelen Island. 

 In the first part of the Preliminary Report it was considered as being identical with Ascidia mentula, 0. F. Midler, a 

 species to which it is closely allied. — (Herdman, Zool. Chall. Exp., part 16, p. 203.)
