Remarhs. — This proposed new species differs from the only other 

 known species, Colanthura tenuis Eichardson, in having a last peraeon 

 somite, which is shorter than the first pleon somite and a pronounced 

 pointed projection at the inner proximal angle of the propodal joint 

 of the gnathopod. In G. tenuis the seventh peraeon somite is longer 

 than the first pleon somite, and no projection is evident on the propodal 

 joint of the gnathopod.
