Pacific Alpheids II — Banner 
193 
Athanas Leach 
Athanas djiboutensis Coutiere, 1897 
For synonymy, see Banner, 1956. 
localities: One specimen each at E-l-290 
and E-l-388. 
discussion: The two specimens cannot be 
assigned positively to this species for they are 
both fragmentary, lacking their chela and 
some other appendages. However, the ap- 
pendages still remaining, and especially the 
form of the rostrum and the orbital spines 
about the eyes, compare almost perfectly with 
the specimens from Saipan identified as this 
species. 
Athanas marshallensis Chace 
Fig. 2 
Athanas marshallensis Chace, U. S. Natl. Mus., 
Proc. 105(3349): 17, fig. 8, 1955. 
localities: One non-ovigerous female 
from E-l-122. 
discussion: This specimen differs in only 
one way from the description and figure of 
Chace: in this specimen the extracorneal 
spines reach almost to the anterior margin of 
the eyes, instead of midway along the eyes as 
in Chace’s specimens. It is likely, however, 
that the eyes are rotated backwards towards 
the body, for the "collar” of the anterior 
carapace that usually fits snugly about the 
eyes is loose and stands out from the corneas 
in this specimen.
