ALPHEUS Fabricius 
MEGACHELES GROUP 
? Alpheus lanceostylus Banner 
Alpheus lanceostylus Banner, 1959. Pacific 
Sci. 13(2): 136, fig. 3. 
LOCALITY: Samoa: 1 specimen from BAS 5. 
DISCUSSION: This specimen is lacking both 
the large and small chelae, and cannot be as- 
signed to this species with certainty. When 
compared with the type specimen for A. lanceo- 
stylus, no points of difference were found ex- 
cept for very slight differences in proportions; 
however, it also agrees quite well with A. ed- 
mondsoni (Banner). The specimen has been 
placed in this species because it has a slightly 
thicker antennular peduncle than is normal for 
A. edmondsoni.

Alpheus crockeri Armstrong 
Crangon crockeri Armstrong, 1941. Ameri- 
can Mus. Nov. ( 1 137 ) : 8, figs. 2, 3.

Alpheus tuthilli Banner, 1956. Pacific Sci. 
10(3): 338, fig. 9. 
LOCALITIES: Samoa: 1 specimen from BAS 
13; 4, BBS 3. 
DISCUSSION: Careful comparison of the des- 
criptions of A. crockeri and A. tuthilli, and of 
these specimens from Samoa with the speci- 
mens from Hawaii, leaves no doubt that A . 
tuthilli is a synonym.
