168 NATURAL SCIENCE [September 
as the moment the rock was overturned they would rush in and 
seize any hapless worm or other small, soft animal which might be 
exposed ; many fine specimens were lost in this way. Several 
holothurians were found at Port Antonio which were not seen else- 
where ; one of them was remarkable, not only for its large size and 
unusual facility of locomotion, but also for its habit of eviscerating 
as soon as brought to the surface of the water, so that it was impos- 
sible to procure perfect specimens. Several species of echinoids, not 
seen on the south side, were found here, but Zoxopneustes was com- 
paratively rare, only a few small specimens being found. The large 
brown Lchinanthus was not uncommon, and the huge Meoma, which 
we found common near Drunkenman Cay, was plentiful and was 
twice the size of those we saw on the south side. Two other very 
pretty little spatangoids, Brissus and Echinoneus, were very common 
in the same situations with Chirodota. The commonest sea-urchin 
was the dark reddish-brown Echinometra, which simply covered the 
rocks in some places. Some very handsome gastropods were 
collected on the reefs, and the large conch, the shell of which is so 
common in America for ornamental purposes, occurs plentifully all 
through the harbour. Along the sandy shore, near the lighthouse, 
the same white Hippa which we saw at Montego Bay is common, 
but on the shore of East Harbour, where the sand is mixed with 
black mud, occurs a somewhat smaller dark-brown Hippa, which 
differs from the other in habits as well as in appearance. Dredging 
proved more interesting than at Port Henderson, especially in East 
Harbour where there is a good deal of eel-grass on the bottom. 
Here we found large numbers of the beautiful Cubomedusa, 
Charybdea, which we rarely saw at the surface, and in the same 
locality the delicate olive-green sand-dollar, Mellita, is quite 
common. 
The fresh-water and land fauna at Port Antonia is especially 
interesting on account of the numerous streams and the proximity 
of the hills. The streams abound with gastropods and shrimps, and 
large, beautifully coloured cray-fish are common. Insects are not 
particularly numerous or noticeable, but myriapods and arachnoids 
are abundant. Pseudoscorpions and pedipalps are both plentiful, 
and scorpions are not rare. Large centipedes with their yellow eggs, 
two or three millimetres in diameter, were frequently brought to us 
by the coloured boys, while equally large millipedes were common in 
the woods. Only a single specimen of Peripatus was found, and 
that was a small one; but we were told that they were not con- 
sidered exceptionally rare. The land-crab at Port Antonio is very 
different from the one at Port Henderson, the two being distin- 
guished as the ‘ black’ and ‘ white’ land-crab, respectively.  Land- 
molluses, especially large slugs, are very common, and the eggs of
