Two conclusions may be drawn from Table 
1. First, a single series of collections, such as 
that made at Tutuila, or on both Samoan islands 
(or in Fiji and Tonga, or most of the other 
archipelagoes that have been or will be reported 
upon), does not approach a complete account of 
the shallow water fauna, even if different types 
•of environment are deliberately sought. Thus, 
it is estimated that the combined Samoan col- 
lections, listing 58 species and subspecies, lack 
somewhere between 25 and 50% of the species 
found in the archipelago. Second, if the number 
of species is far from the total number that 
could be recorded, those specimens not collected 
are relatively rare in the environments that 
could be sampled. For example, of the 47 species 
collected on both trips to Tutuila, 17 or almost 
33% were collected on the first trip but not on 
the second, yet these 17 species were represented 
by only 83 specimens of the 1240' collected, 
or 6.9% of the total for the island. 
COLLECTION LOCALITIES 
All copies of detailed field records of the col- 
lecting localities were destroyed in the fire, but 
fortunately maps showing geographical location 
of the field stations were in the hands of the 
staff artist. These field locations were sufficient 
to recall to the senior author some details of the 
collecting sites. Dates were obtained from per- 
sonal letters. 
Stations in Fiji , Viti Levu 
BF 1-18. At Korolevu, on the southern coast, 
during the week 14-20 March 1954. Here the 
reef investigated was of fringing type lying 
along the shore, well within the barrier reef 
complex of the archipelago. The beach was of 
beach rock and sand; the immediately adjacent 
water was the "lagoon/’ perhaps 2 or 3 ft deep 
at low tide. Seaward the reef platform rose to be 
exposed at low tides, but with the numerous 
potholes and cracks bearing living coral; the
