Bee ‘* ENDEAVOUR” SCIENTIFIC RESULTS. 
Adambulacrals about 57 on each side of each furrow, dis- 
tinctly longer than wide, except near arm-tips ; furrow margin 
with 8 conspicuous spines, the adoral and aboral ones being 
distinctly smallest, the others about 3 mm. long ; outside of 
this series is a well-spaced line of 3-5 shorter and more slender 
spines and external to them is an irregular line of 4-6 small, 
slender spinelets ; a few extra spinelets may occur on the outer 
corners of the plates, but there is no tendency to form pedi- 
cellarial groups. No pedicellarie are to be seen. Oral 
plates large, swollen, covered by flattened spinelets similar to 
those on the actinal plates, but distinctly larger ; oral spines 
coarse and heavy, but neither number nor arrangement is 
peculiar. Colour, light dirty grayish, more or less yellow on 
various irregular areas. 
This individual is much larger than either of the species, 
collected by the *‘ Challenger,” and for which the genus was 
established, is known to be, and it is not impossible that it 
will prove to be an adult specimen of L. forcipifer, which was 
taken south of Australia in 1950 fathoms. This seems to me 
highly improbable, however, for the difference in the form, in 
the paxillz and in the matter of pedicellaria are very marked. 
Nevertheless I think there can be little doubt that the two 
forms are congeneric. 
Loc.—Great Australian Bight, 80-120 fathoms.

p. 225. 
Except in size, these four specimens show little diversity ; 
in the smallest R=42 mm.; in the largest R=100 mm. The 
actinal interbrachial areas differ considerably in size in the 
different specimens ; in the one from the Eastern Slope, Bass 
Strait, they are relatively much larger than in Sladen’s figure, 
which answers well for the other specimens. All four indi- 
viduals are somewhat rubbed, and the two largest are in rather 
poor condition ; in none do I find any trace of spines on the 
superomarginal plates. 
Locs.—Eastern Slope, Bass Strait, 80-200 fathoms. 
South of Gabo Island, Victoria, 200 fathoms. 
Great Australian Bight, 80-120 fathoms.
