Remarks.
The Australian specimen differs from the
type
and from
New Zealand
specimen in that the branchiae have five filaments where best developed, rather than two as in the
New Zealand
material. In addition, the subacicular hooks in the Australian specimen have distinctly curved proximal teeth; in the
New Zealand
material the proximal teeth are straight-sided and triangular.
Leodice rubella
resembles
L. bowerbanki
Baird
1869
in that both have branchiae from chaetiger 5; dark subacicular hooks from about chaetiger 30 and distinctly beaded antennae. The two species differ in that the branchiae are far less developed in
L. rubella
in which a maximum of five filaments have been recorded, than in
L. bowerbanki
in which as many as 15 filaments are present. The
type
of
L. bowerbanki
is complete consisting of 142 chaetigers and is
95 mm
; the
type
of
L. rubella
had 112 chaetigers and was
60 mm
long. The difference in size appears to be too small to account for the great difference in numbers of branchial filaments present.
