Alpheid Shrimp, IX— Banner and BANNER

Alpheus edmondsoni Banner 
Alp hern edmondsoni Banner, 1953. Pacific 
ScL 7(1) :78, fig. 26 a-p. 
LOCALITIES: Christmas Island: 5 specimens. 
DISCUSSION: Dr. Doty, one of the collectors 
of this species cited in our 1959 paper (Pacific 
Sci. 13:141), has corrected what was an apparent 
misinterpretation of the label of the specimen. 
The citation should read "Oneroa Island, Raroia 
Atoll. Tuamotu Archipelago . . . collected by 
Morrison, Doty, and Herre. . . .”

LOCALITIES: Canton Island: 1 specimen from 
BC 8; 3, BC 11; 3, BC 13; 2, BC 24. 
DISCUSSION: The characteristics, name, and 
synonymy of this species will be discussed in a 
future paper. 
The one specimen, a male, in BC 8 is ap- 
parently malformed. In all characteristics except 
the antennules and antennae it is like the usual 
specimens of this species, but the antennules, 
while symmetrical, are very short, so that the 
typically reduced scaphocerite reaches to the 
middle of the third article, and one carpocerite 
reaches to the end of the antennular peduncle 
while the other exceeds it by about one-fourth 
its length. This appears to be the result of an 
accident of inheritance or of environment.
