(Allan, 1940) but all other specimens have been taken with open nets
fished to 695-3 000 m with the exception of one caught in a net fished
to 200 m (Voss, 1960a).
Voss (1963s) figured the largest known male with a mantle length
of 11.4 cm and illustrated a penis although no spermatophores were
shown or mentioned in the text. The largest female has a mantle
length of 8.0 cm (Voss, 1960a); whether this female or that described
by Thiele (1921) are mature is not clear.
Published descriptions leave some doubt as to whether the mature
animal has yet been described. There are a number of differences
between Voss’s large Philippine specimen (1963a) and the other specimens described but these differences may well be due to development
as they show the same trends of growth described above for other
taoniids (page 225, Fig. 49). Desbrosses’ (1938) specimen had a mantle
length of only 1.8 cm. This differed from the larger specimens in
having relatively longer eye stalks; the “appendix” of the eye is
much more elongated.
L. Taonidium
This genus contains some specimens in a rather later “stage of
development” than the preceeding forms; the eye stalks and the
rostrum of the head are shorter while the arms are still very short
(Fig. 49).
1. Taonidium chuni (Pfeffer, 1912)
Taonidium sp. juv. Chun, 19108
Specimens referred to this species came from 0’25” 7’E, near
St. Thome (Chun, 1910a; Pfeffer, 1912), and from 25“s 57‘42’E (Thiele,
1921). The type was caught in a vertical net fished from 2 000-0 m.
The type has a mantle length of 0.9 cm.
2. Taonidium suhmi (Hoyle, 1885~)
Taonius suhmii Hoyle, 18868
Procaliates auhmii Lankester, 1884
Hoyle (1885c, 1886a) described several specimens under this name
which vary in shape from a very young larval type with long eyestalks
through a later larval type with short eyestalks and small arms to a
larger specimen with relatively long arms. There is little basis for the
belief that these are all the same species as they came from widely
dispersed stations. Chun (191Oa) considered these were juveniles of
Qaliteuthis arnucta and referred two of his own specimens to 8.
