“That the reader may have a clear idea as to what part of that mono- 
graph the Academy published, and what part we propose to bring out in 
this 'Bulletin, a summary of its contents is here given just as it was when 
completed, 'December 23, 1893. 
“monograph of the 3'IARINE tertiary MOLLUSCA of TEXAS. 
“By Dilbert Denison Harris. 
‘^Preliminary Remarks, pp. 1-5 (all pages are type-written). 
Part 1. Brief review of the literature of the Tertiary mollusea o-f 
Texas, pp. 6-2il. 
Part 2, (Eocene mollusea of Texas, pp. 22-352. — The name, author, syn- 
onomy, original description, additional remarks, all knoiwn localities for 
each species in Texas, important localities in other States, geological range, 
and where the type specimen may now be found. 
Addenda to Part 2. 'New or interesting Eocene mollusea from other 
States, pp. 353-357. 
Part 3. Neocene mollusea of Texas, or Fossils from the (Galveston deep 
well, pp. 358-397. — ^^The name, etc., as in Part 2, and the range in depth 
of eaich species. 
Part 4. Definition and eorrelation of the marine Tertiary deposits of 
Texas, pp. 398-409. — ^Section 1. Beview of the works and opinions of 
earlier writers. — ^Sec. 2. 'Conclusions drawn from the present paleontolo- 
gical study. 
“The last mentioned part is followed by ( 1 ) a detail account of all the 
localities or stations whence the Tertiary fossils were obtained, (2) a 
table showing at a glance the geographical distribution of the Eocene 
mollusican species in Texas and their geological 'range in this State and 
others farther east, (3) a table showing the bathymetric distribution of 
the Galveston well fossils, pp. 410-434, and (4) 36 large octavo plates 
illustrating the species mentioned or described in Parts 2 and 3. 
“The article published by the Academy contained the description of the 
new species of Part 2 and the figures belonging thereto; the majority of 
that part, and which alone is of present stratigraphic value, still remains 
in manuscript. 
“This Bulletin is practically a condensation of Part 3. It seems advisa- 
ble that this unique material should no longer remain unpublished, for up 
to this date no other marine Neocene fossils are known from the Gulf 
slope west of Mississippi. The opinions expressed, regarding the age of 
the deposits penetrated, in the American Journal of tScience. Vol. 46, p. 
42, and in the 4th Annual 'Report of the Btate 'Survey, 1893. are still 
maintained. * * .” (See Title No. 181.)

'poda, with characterization, and range in depth follows.
