of the chela. The larger and deeper of these two inconspicuous 
grooves runs back from the articulation of the movable finger ; the 
other, a little below the articulation, is shorter than the larger groove. 
The tip of the rostrum extends very little or scarcely in front of a 
line joining the anterior margins of the orbital hoods. 
Dr. Edmondson writes me that he is unable to find anv evidence of 
•/ 
these longitudinal grooves on the outer side of the palm, and that the 
rostrum of his C. Jwwaiiensis is even longer and sharper than indi- 
cated in his figure, that it extends to a greater distance beyond the 
orbital hoods than is shown in the figure, and that the terminal por- 
tion of the rostrum is verv narrow. 
The specimens we have are certainly distinctively dififerent froim 
C. hazvaiiensis on the basis of the character of the larger chela and 
the rostral length alone. Therefore, in spite of the close agreement 
between our specimens and the type of the species in almost all other 
points, I venture to refer to them as the Clipperton Island subspecies' 
of Edmondson's species, 
Crangon paracrinitus IMiers variety .4 
These four specimens seem to bridge the dififerences existing be- 
r t * ' 
tween the species proper and' ifs^ known variety hcngalcnsis Coutiere. 
As in that variety, our specimens lack the spine with which the minor 
chela of the typical is armed. On the other hand, the proportions of 
the carpal joints of the second legs are more like those of the typical 
specimens than those of the varietal form. The rostrum of our speci- 
mens is small, there are no orbital grooves, and the hands and carapace 
are smooth. I do not feel justified at this time in giving these variants 
of C. paracrinitus a name.
