a fever it is thickly dotted with them. A few 
other Strophias peculiar to the Bahamas are 
found on this island. Helix provisoria is very 
abundant; also Bulimus sepulchralis, Steno- 
gyra octona, and a goodly number of many 
other land shells. 
The rocky parts of the sea-shore of New 
Providence abound in specimens of Nerita 
tessellata, versicolor and peloronta together 
with Chitons, Patellas, Fissurellas and Littor- 
inas. On the south side of the island there is 
quite an extent of very shallow sea the bottom 
of which is covered with sea weed inhabited 
by numerous crustaceans, echinoderms, Naticas 
and Cerithiums. Asaphis deflorata and Co- 
dakia tigerina are found buried in the sand; 
while near the shore in brackish water Perna 
ephippium may be found in masses fastened 
by its byssus. In fact everywhere, around 
and on the island are many things of interest. 
Adjacent to New. Providence are Porcine, 
Athols, Rose, and some other small islands 
about which are many beautiful and interes- 
ting coral groves, where the Gorgonia, the 
Pterogorgia, and a whole world of marine 
animal and plant life flourish in all their glory. 
Although it would “pay” to visit this part of 
the Bahamas only, the expedition would be 
incomplete without going to a number of the 
other islands such as Abaco, Cat, Andros, 
Watlins, Exuma, Fortune and Inagua, for 
each of -these islands has something of pecu- 
liar interest. Inagua abounds with Strophia 
alvearia and variety rubicanda. Helix Mill- 
eri is found at the Fortune Islands, covering 
the bushes; Helix salvatoris at Exuma; Helix 
varians at Rum Key; and at places on Cat 
Island very fine Strophia mumia and Martensi 
are met with, Generally speaking what is 
scarce on one island is very abundant upon 
another; and the same is true of marine shells. 
All the islands are easily visited from Nas- 
sau as it is the seat of government; the bulk 
of the business being transacted there, while 
vessels are constantly arriving from and de- 
parting to the various islands. Each of the 
Bahama Islands is little more than a mass of 
coral rock, and their shores are either this 
naked rock or a beach made up of coral sand. 
The rocky parts abound with the Chiton, Pa- 
tella, Fissurella, Nerita, Littorina, etc.; and 
where the waves are most tumultuous is the 
home of the Turbo pica, Purpura patula and 
some others; while the Arca and Fasciolaria 
choose the more quiet nooks and bays. All 
these can easily be collected in any number; 
but those that live among the corals and the 
reefs and out on the bars the collector will 
often find much difficulty in getting, for they 
seldom wash ashore in good condition, and 
they can be gathered only when the water is 
still; and one may wait in vain for days for 
such an opportunity. 
The large Cassides and Tritons, Dolium 
galea, Strombus accipitrinus, Turbinella scol- 
ymos and others are generally picked up by 
the spongers and other fishermen to supply 
the ordinary curiosity hunters who would 
neither know what an operculum was or care 
for it, so the fishermen do not save it. Al- 
though I have written more than I intended 
yet only here and there among the many 
things has a bare mention been made of those 
that interest collectors; and all these attrac- 
tions are only a little way down where per- 
petual summer reigns; where there is every- 
where and always spread a most bounteous 
feast on naked rocks and under the sylvan 
shades of a glorious glossy green, as well as 
“* Deep in the wave is a coral grove 
Where the purple mullet and gold fish rove, 
Where the sea-flower spreads its leaves of blue 
That are never wet with falling dew; 
3ut in bright and changeful beauty shine 
Far down in the green and glossy brine. 
The floor is of sand like the mountain drift 
And the pearl-shells spangle the flinty snow.’
