80 BULLETIN: MUSEUM OF COMPARATIVE ZOOLOGY. 
There are many foraminifera, and bits of coral are numerous. A few spines 
of echini were noted, and also a few bryozoa. Lamellibranchs are not numer- 
ous, and gastropods are very rare. 
1,200 feet. — Color light hrownish gray. Trace of quartz sand present. 
In the coarse portion of the sample there are many bits of porous rock, some of 
compact, and a few of odlitic. Much of the finer stuff is rounded, Some ovules. 
Foraminifera abound, and the curiously distorted Orbitoides have reappeared. 
Jits of coral are not uncommon, but there are very few remains of echini and 
bryozoa present. Lamellibranch remains are common, and gastropods are 
scarce. Noted some annelid (7) tubes. As usual, however, most of the material 
is unrecognizable. 
1,325 feet. — Color light brownish gray. Almost no quartz sand, but an 
occasional particle may be noted in the fine stuff. Four fifths of the sample 
went through the No. 40 sieve. Originally a porous sand-rock ? Ovules are 
rather numerous. Many foraminifera were noted, some of different genera than 
any heretofore observed. Bits of coral not uncommon.  Echini seem to be 
absent. "There are a few bryozoa. Lamellibranchs are common, but gastropods 
rare, as usual. 
1,350 feet. — Color light brownish gray. Quartz sand very small in amount, 
but of same character as before. Comparatively little of the sample went 
through the sieve. The residue shows that the rock was very porous, and con- 
tained many rounded grains of sand and some ovules. The rock also contained 
some nodules of compact limestone. It appears to be different from the 1,325 
foot sample. Determinable organic remains were not very abundant, but I | 
noted foraminifera (Orbitolites, ete.), соға! (7), two or three spines of echini, 
and a few bits of bryozoa. Gastropods (Dentalium, ete.) were scarce, and 
lamellibranchs not numerous. 
1,375 feet. — Color light brownish gray, with yellow cast. The quartz sand 
seems to be wanting. At least nine tenths of the sample went through the 
sieve as a rounded sand. In the residue are some bits of friable porous rock, 
and a few of compact stone, as if of nodules. Ovules (1) are present. Foram- 
inifera are numerous, and some Orbiloides are large, one measuring 3.5 mm. 
across. Textularia appears. Several fragments of madrepores were noted. 
Spines of echini and the facetted bits are few in number, and so too are 
bryozoan, lamellibraneh, and gastropod remains. 
1,400 feet. — Very light brownish gray. Of quartz sand there is but a trace. 
The rock seems to have been a very porous limestone, and coarse, loosely com- 
pacted sand-rock containing nodules of solid limestone. Some ovules and a 
few bits of oólite were noted. Foraminifera are numerous, and some (Orbitoides) 
ате as much as 4mm. in diameter, Тһе Textularias are common. Many bits 
of madrepore coral. A few spines and plates of echini. Bryozoa are very 
rare, and gastropods, and even lamellibranchs, are not common. The propor- 
tion of coarse material and determinable fragments is large. 
1,425 feet. — Color very light yellowish brown. Quartz sand a mere trace, 
but the grains can be distinguished readily under the microscope, as is the case
