HOVEY: ARTESIAN WELL AT KEY WEST. 83 
seems to be another rather coarse sand-rock with somewhat less fine material 
than the last, but containing also some solid and some porous limestone. А 
few ovules? Foraminifera abound, especially the textularias, A few frag- 
ments seem to be bits of madrepores. Spines (and plates) of echini аге com- 
paratively numerous, Some bryozoa are present, but lamellibranch remains 
are very scarce and gastropods seem to be absent. 
1,775 feet. —Color light brownish gray. A very few particles of the an- 
gular quartz sand. Seems to have been a moderately coarse sand-rock like the 
preceding, but with very few bits of either solid or porous limestone. There 
seem to bea few ovules. Foraminifera of the several genera already noted 
are very abundant. Spines and plates of echini are comparatively numerous 
(perhaps some are from starfish). Some remains of lamellibranchs and a few 
minute gastropods were observed. 
1,800 feet. — Color light brown with white particles. Trace of the quartz 
sand. The sample consists of a fine calcareous sand more than nine tenths of 
which passed through the No. 40 mesh sieve, and there are no very coarse par- 
ticles in the residue, though there are a few small angular chips of solid lime- 
stone. Some ovules? Not much is determinable, but most of what is consists 
of foraminifera, Noted also a few spines of echini, some branching bryozoa, 
and a very few fragments of Jamellibranchs. Gastropods seem to be absent. 
1,825 feet. — Color light brownish gray with yellowish cast. Trace of the 
quartz sand. The sample is a fine calcareous sand, three fourths of which 
passed through the sieve. Some small angular bits of solid limestone appear 
in the coarser portion. Among the determinable forms foraminifera abound 
and the Textularias are the most numerous of these, Orbitotdes also. There 
are also some spines of echini, a few bryozoa and lamellibranchs, and possibly 
a very few gastropods, 
1,850 feet. — Color light brownish gray with yellowish cast, like the pre- 
ceding. Quartz sand, a trace. The sample is a calcareous sand like the last, 
except that the proportion of coarser particles is rather greater. Organic con- 
tents like those of the last ; mostly foraminifera of the usual genera with a few 
spines of sea-urchins, bryozoa, bits of lamellibranch shells and a very few 
gastropods. Тһе Tewtularias predominate among the foraminifera. Among 
the coarser particles are some bits (or masses) of rather densely compacted 
sand-rock, and some angular bits of solid limestone. 
1,875 feet. — Color light yellowish brown with many white particles, Trace 
of quartz sand. "The sample is for the most part a very fine calcareous sand, 
nine tenths of which passed through the sieve. In the residue were some very 
angular bits of dense and porous rock and oölite. Loose ovules are not un- 
common in the sand. Among the numerous foraminifera are some very large 
Textularias, Orbitoides, ete. A very few fragments look like madrepores. 
Spines and plates of echini are not rave, Bryozoa are scarce. There are a 
few remains of lamellibranchs and fewer of gastropods. One of the last is 
the internal cast of a purpuroid shell, possibly a Pseudoliva, about 3 mm. high. 
As usual, nearly all the sample consists of rounded, undeterminable grains,
