Fig. A. A bathymetric chart of the areas immediately adjacent to the Hawaiian Islands, showing a major 
break in slope between the 1,000- and 3,000-ft isobath. Stations HA, in Hanauma Bay, and T-13, on Penguin 
Bank, contain Recent ostracodes exclusively; the remaining stations contain only fossils. 
import concerning Pacific faunas was the de- 
scription of the Ostracoda collected during the 
Challenger Expedition, also by G. S. Brady, 
published in 1880. This was primarily a taxo- 
nomic treatment of the ostracodes obtained 
from dredgings in many parts of the world by 
the Challenger Expedition during the years 
1873-1876. Though an excellent work in 
certain respects, and well illustrated, it was 
little better than a reconnaissance. 
Brady again published in 1890 on the Os- 
tracoda from some South Sea islands (New 
Caledonia, Samoa, and Fiji). His entire collec- 
tions consisted of species found from the littoral 
zone to 6 fathoms. Though certainly not a com- 
prehensive study of South Pacific ostracodes, 
this, together with his 1880 work, constitutes 
the bulk of descriptive information available on 
this group in the tropical Pacific. 
J. Th. Kingma (1948) described 94 species, 
40 of which were new, from Tertiary to Recent 
deposits of the Netherlands East Indies. He 
reported relatively few tropical Pacific island 
ostracodes living in the Java Sea. Shorter works 
in the Indo-Pacific realm include studies of late 
Cenozoic fossils by Le Roy (1939, 1941) and 
Doeglas (1931), and of Recent ostracode 
studies by Chapman (1902, 1910), Triebel 
(1954), Keij (1953, 1954), 1964), Fyan 
(1916), and Bold (19 46b, 1950). 
Major contributions have been made in the 
New Zealand and the South Australian regions; 
however, these faunas are distinct from those of 
the tropical Pacific region. For an historical 
discussion of that area the reader is referred to 
Hornibrook (1952). The history of ostracode 
study in the north Pacific-Japan area is 
treated thoroughly by Hanai (1959). 
age and paleoecology: Menard, Allison, 
and Durham (1962) interpreted the age of a 
single station (AR of this study) to be prob- 
able Late Miocene on the basis of the ratio of 
extinct coral species to living species and on 
vagaries in shape of specimens of Globtgeri- 
noides quadrilobatus. The hermatypic corals in- 
dicated an initial depth of only 10 m. Allison 
(personal communication) has since expressed
