BARBADOS-ANTIGUA EXPEDITION 187 
Barbados-Antigua expedition. The squame of the antenna, 
however, seems absent. 
Of course there were almost innumerable instances of camou- 
flage among the small crabs secured in the tide-pools and by 
pounding up pieces of rock. Many bore sponges on their backs, 
or were hairy or mossy in appearance. Some were dark green 
like the vegetable growths among which they lived. Others 
resembled corallines. One little crab (Thoe puella) is carmine 
pink with very conspicuous irregular blotclies of white on the 
carapace and legs. It is probably camouflaged to resemble a 
coralline covered with an irregular incrustation of white Bry- 
ozoa. The entire surface is packed with smooth hemispherical 
tubercles. The chele are relatively small, slender and of equal 
size. The walking legs have the merus greatly flattened and 
hollowed on one side so as to make a pocket which resembles 
that of tibie of humble bees for carrying pollen. The legs bris- 
tle with spines, hairs, ete., so that the creature reminds one of 
some of the mites, greatly magnified, of course. 
There were many, however, that were notably conspicuous in 
color, vivid reds predominating. These could not be protect- 
ively colored, as red is usually absent in their environment or at 
least not common. I remember one quite flat species that was a 
very dark olive, but the chele were sharply marked with lines 
of brightest yellow. Here, as at Barbados, the chele seemed 
the seat of the brightest ornamentation. It may be that this in 
a way serves the purpose of warning coloration among land 
forms such as wasps and bees, calling attention to their weapons, 
as it were. One little crab was quite pale in color, but the 
fingers were jet black. Some species common at Barbados, e. g. 
Cardisoma, or red land-crab and the triangular Leptopodia 
sagittaria were not seen at all at Antigua. 
Echinodermata.—Here, as at Barbados, the paucity of star- 
fish was remarkable. With the exception of a few minute forms, 
the only species found was the widely distributed West Indian 
Oreaster reticulatus. Mr. Greenlaw found a place in Falmouth 
Harbor where these were fairly abundant, and collected a num- 
ber of specimens for laboratory use. This is the species most 
frequently encountered in curio stores in Florida and elsewhere.
