HOPLOPHORIDZ. 159 
near the distal end. The inner blade is a trifle shorter than the telson ; it is 
also fringed along its whole margin with long hairs. 
Dimensions of a female specimen: length of body, rostrum included, 
139 mm. ; length of rostrum, 55 mm.; length of carapace, rostrum included, 
61 mm.; length of telson, 20 mm.; length of antennule, 267 mm.; length 
of antenna, 515 mm.; length of antennal scale, 19 mm. 
This species, like all the Mematocarcini, is very fragile. The long and 
slender rostrum is often broken off during life, and the attempt to restore it 
sometimes results in an abnormally small and otherwise monstrous rostrum, 
which might easily be mistaken for a specific character if ample material 
were not at hand.
