outermost edge of the reef was of coral and 
coralline algae. A few hundred yards away from 
the collecting area was the mouth of a small 
stream; the coral reef did not extend across its 
mouth, but dropped off abruptly to a sandy bot- 
tom about 20 or more ft deep. The stations were 
on a line crossing the reef from the innermost 
lagoon to the seaward edge (no diving was done 
off the seaward edge because of storm waves) 
and at the edges of the stream basin; the exact 
location of the individual stations cannot be 
recalled. 
BF 19-20. On the barrier reef protecting 
Suva Harbor, 11-13 April 1954. Here the bar- 
rier reef surface was largely exposed at low tide 
but, except for the seaward edge, was almost 
devoid of living coral, being composed instead 
of broken coral fragments. The first station was 
on the seaward sector of the reef, the second on 
the lagoon side.

Stations in Tonga 
All collections were made on Tongatabu be- 
tween 27 March and 7 April 1954. 
BT 1, 2, 4, and 6. On the sandy shore and 
bottom of the harbor of Nukualofa (near the 
point marked on U. S. Army Map Service Map 
[x622, 1943 ed.} as "Mine Layers’ Pier”) and 
the specimens were collected from dead coral 
heads between the intertidal zone and water 
about 8 ft deep. 
BT 3 and 14. Off Nukunuku Island near 
the mouth of the large brackish lagoon; most 
specimens were collected under dead coral boul- 
ders lying on the broad sand and dead coral 
flats, and were exposed at low tide.' 
BT 7 and 8. On the Nukualofa side of 
Pangaimotu in relatively protected waters, BT 7 
being from living and dead coral slightly be- 
low the intertidal zone, BT 8 being somewhat 
deeper. A moderate amount of growing coral 
was found in this area.
