FIJL-NEW ZEALAND EXPEDITION 41 
very slender and finely barbed set and knobbed pedicellarie. 
These spines remind one of Aspidodiadema. Of serpent stars the 
most common was a black Ophtocoma. There was a smaller species 
barred greenish and white, one with brilliant scarlet on the upper 
side of rays, and several others. There were holothurians mottled 
chocolate and white in color, and black forms allied to Stichopus, 
with tubercles of the same color; also, a smoother black one said 
by our Fijians to be edible. 
Of the Crustacea there was a small blue crab on the big blue 
starfish; mantis shrimps mottled greenish and whitish above and 
with four marginal purple spots, appendages green with white 
spots on margins, and chelz tipped with purple. Another, a macru- 
ran, was a greenish form with red walking legs and very large 
chelez. Of brachyurans there was a quadrate form, blood-red and 
green with whitish lines, allied to the ‘‘Sally light-foot’’ of the 
West Indies. The number of crustaceans in any good locality was 
prodigious. Alfred broke open a mass of coral rock and secured 
a remarkable slender legged macruran, white, with blood-red an- 
nular markings on the body and appendages, the latter bearing 
many spines and conspicuous markings of bright blue on the red 
annulations. 
There was a profusion of various kinds of mollusks. Perhaps 
the most interesting (to us) was the well known Tridacna which 
attains the greatest weight of any modern bivalve. It will be 
described later. There were several Turbo, Leucozonia, Cerithium 
and a heavy gastropod with a remarkably thick operculum, hemi- 
spherical in shape; three species of Conus, a Crepidula adhering 
to a Turbo, Spondylus, several fine species of Cyprea and a 
Natica. Interesting nudibranchs were common; one, white mottled 
with brownish and another bearing eggs on its back. A small 
Octopus emitted much ink when disturbed. There were several 
worms, one related to Nereis, a very slender brown and yellow 
annelid and some tube-dwelling forms. 
Perhaps the most interesting assemblage we saw was a pro- 
fusion of Celenterata, among which were a brilliant blue hydro- 
coralline, corals belonging to the genera Agaricea Meandrina, 
Pocillopora, Siderastrwa, very brilliantly colored Acropora and 
other genera not familiar to me. There were literally acres of 
compound anemones, very large simple ones with numerous brilli- 
ant green tentacles, orange red bodies and profusely lobulated 
oral dises. A beautiful alecyonarian grew in large lobular patches
