not rare, — more numerous than heretofore.  Remains of echini unusually 
scarce. Bryozoa scarce, but include branching and incrustiny forms. Remains 
of lamellibranehs rather numerous, but few gastropods recognized. Spicules 
of Gorgonias. Proportion of recognizable remains seems rather less than in 
the last, 
975 feet, — Color very light yellow brown. Sample shows more evidence of 
being comminuted rock. Quartz sand scarcely perceptible. Ovules occasional, 
and rounded grains very numerous, Foraminifera (Orbitoides and others) 
abundant. A few pieces of coral were noted. Bits of echini occur, and facetted 
fragments are numerous. Bryozoa not observed. Remains of lamellibranchs 
numerous, but those of gastropods scarce. Seems to have been a loosely com- 
pacted, rather coarse sand-rock. 
1,000 feet. — Color light yellowish brown. Quartz sand scarcely perceptible. 
The sample contains a considerable proportion of coarse sand and fragments. 
Ovules not noted, though rounded grains are numerous. Foraminifera of 
several genera abundant, — Amphistegina, Orbitoides, the globular one, ete. 
Bits of madrepore coral frequent. Annelid tubes and Serpula (?) or Vermetus (2). 
Fragments of tests of echini (Spatangus 7).  Lamellibranchs as usual, and 
gastropods not uncommon; of the latter, Turritella, Майса? Caecum, and 
Dentalium were recognized. Bryozoa present. Spicules of Gorgonia. 
1,025 feet. — Color very light yellow-brown. Trace of quartz sand. Sample 
is fine calcareous sand with the coarser remains of organisms. Ovules not 
noted, but rounded grains are common. Foraminifera very abundant. Small 
bits of madrepore coral not infrequent. Both branching and inerusting bryozoa. 
Lamellibranch remains as usual. Caecum and Dentalium observed, and other 
minute gastropods frequent, 
1,050 feet. — Color very light yellow-brown. Trace of quartz sand. No 
ovules noted. Foraminifera form the principal constituent of the coarse part 
of the calcareous sand. A few pieces of coral. Bryozoa as in last. Remains 
of lamellibranchs common, but gastropods scarce. 
1,075 feet. — Color very light yellowish brown. Trace of quartz sand 
stronger than in last. The sample is a very fine sand, with only a few frag- 
ments in it too coarse to go through the sieve. In the residue there were 
foraminifera, a few bits of coral, a single spine of an echinus, some bryozoans, 
and more lamellibraneh remains. Ovules are present in the sample, but very 
scarce. 
1,100 feet. — Color light brownish стау. Trace of quartz sand. „Тһе sample 
is a fine uneompacted calcareous sand, containing a much larger proportion 
of coarse particles and fragments than the last. Ovules seem to be absent. 
Foraminifera of several genera are numerous, Bits of madrepore corals are 
very numerous, Bryozoa of both branching and incrusting forms are not rare. 
Lamellibranch shells and casts are present in abundance, but gastropods are 
scarce. I noticed a few spines of echini also, and some of the facetted fragments 
described in the earlier part of these notes. 
1,125 feet. — Color light brownish gray. Very slight trace of quartz sand.
