150 
of water. Specimens were collected from dead 
and live coral which was found in depressions 
at the inner edge of the reef which is several 
hundred yards wide. 
BP 4. At Alofau on Fagaitua Bay on the outer 
face of the fringing reef in water approximately 
3-10 ft deep. Specimens were collected from 
living and overgrown heads of dead coral. 
BP 5. At Utumea on the southeastern side of 
the island, from the middle reef flat, at about 
0 ft tide level. Collections were made from old, 
rather solid, heads of dead coral. 
BP 6, 6a, 7, 8, and 9- Various localities on 
the reef flat at A'umi (east of Lauli'i). BP 6 
was the inner area of the reef; BP 6a was located 
in an encrusting tube; BP 7 was from corals 
taken in a protected portion of reef flat; BP 8 
and 9 were located in the surge zone. 
BP 10. At Leone on the southwestern side of 
the island. Specimens were collected from heads 
of dead coral from the reef flat in water 2-3 ft 
deep. The water was brackish and carried silt 
from the land; the bottom was fine sand and 
mud mixed with a great deal of organic detritus. 
BP 11. At Pago Pago between Aua and 
Breaker Point. Specimens were collected from 
heads of coral lying near the surf zone. 
BP 12, 12a, 13. At Lauli'i, in water 2-3 ft 
deep; BP 12 was near the middle reef; the speci- 
men from BP 12a was found commensal with 
a brittle star; and BP 13 was near the reef edge. 
BP 14 and 15. In the entrance to the lagoon 
near the airport ( Cocoanut Point on the chart ) . 
The area was subject to more than the usual 
amount of fresh water run off. BP 14 was taken 
from dead coral heads in about 3 ft of water 
from a shallow broad flat where the bottom was 
of silty sand with organic debris. BP 15 was 
located under boulders on the shore at about 
middle tide zone, in very fine sand. 
BP 16. At Fangasa'a, located on a deep inlet 
on the leeward side of the island. Specimens 
were collected from dead coral heads on the 
outer face of a flourishing reef on the west side 
of the bay in about 3-15 ft of water. 
Stations in Western Samoa, Upolu 
Collections were made from 25 April to 12 
May 1954. 
BBS 1-3- On a transect across a broad fring- 
ing reef at Fagalii east of Apia. BBS 1 was the 
PACIFIC SCIENCE, Vol. XX, April 1966 
most inshore; BBS 3 was almost at the surf zone. 
BBS 4. An inshore area at Vaiala a short dis- 
tance east of Apia. 
BBS 5-10. On a transect across the broad 
fringing reef at Vailutai in the Fasito'outa dis- 
trict; here the reef was several miles broad, but 
without a boat lagoon as is found closer to Apia. 
The maximum depth on the reef was approxi- 
mately 8 or 10 ft, rising again to a shoal reef 
front; the submerged reef flat was sandy with 
scattered coral; the reef front consisted of vigor- 
ously growing coral. The stations ranged from 
the shore, where there were freshwater springs 
below the low tide zone, to the outer face of the 
reef front. The stations were not in numerical 
order. 
BBS 11. On a vigorously growing coral reef, 
in depths to about 20 ft, on the eastern side of 
Apia Harbor near Matautu.

DISCUSSION: In addition to these specimens, 
and those previously reported from Saipan and 
under the name A. johnsoni (Banner 1956: 
321), there are some in the collections from the 
Cook, Society, and Marshall islands to be re- 
ported upon in later papers, a total of 17 speci- 
mens. Unfortunately many of these specimens 
are small and broken, and most are lacking their 
chelae. 
This series of specimens appears to bridge all 
but one of the criteria used by Chace to separate 
A. johnsoni from A. gardineri. He stated that 
the rostrum in the form found in the Marshall 
Islands was triangular instead of rounded; in 
this series both types of rostrums occur, and in 
one large specimen from Eniwetok the rostrum 
is rounded. In A. johnsoni the second antennu- 
lar article is 2.5 times as long as broad, while 
in A. gardineri the same article is 4 times as
