 61 mm. ; length of telson, 20 mm. ; length of antennule, 267 mm. ; length 

 of antenna, 315 mm.; length of antennal scale, 19 mm. 



Tliis species, like all the JVemalocarcm, 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.
