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. A 

 few ovules ? Foraminifera abound, especially the textularias. A few frag- 

 ments seem to be bits of madrepores. Spines (and plates) of echini are 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 be a 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 lamellibranchs. 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. Orbitoides 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. The Textularias 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 oolite. Loose ovules are not un- 

 common in the sand. Among the numerous foraminifera are some very large 

 Textularias, Orbitoides, etc. A very few fragments look like madrepores. 

 Spines and plates of echini are not rare. 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.
