Hincks places as synonymous with C. Ellisii, Flem., 
and the C. zelanica, Busk (‘ Voy. Rattlesnake,’ vol. i. 
p- 378), as the same as C. Boryi, Aud.

In speaking of the vibracula, &c. of C. Boryi, Mr. Hincks says (p. 
58, op. cit.) : ‘In this species there not only are the individual append- 
ages highly developed, but the whole company of them attached to a 
colony are brought into combined and harmonious action. It must be 
left to future observation to determine the precise structural conditions 
on which these remarkable movements depend ; but they certainly seem 
to imply the ewistence! of a nervous system, distinct from that of the indi- 
vidual polypides, by which the vibracular zooides are controlled and brought 
into relation.’

three of which are new.

This name is substituted by Mr. Busk for Gray's New Zealand species 
(Selbia Zelanica), after having fully satisfied himself that the species is 
quite distinct from ‘ Caberea boryi, under which appellation, both 1 and 
other authors have confounded two or three quite distinct species.’.—Busk, 
‘ Chal. Rep.’ p. 29.
