 two plumose hairs at the center, which is dentiform. 



One of the larger specimens has the total length, from tip of 

 telson. 45 mm; length of carapace from orbit, 8mm; of rostrum, 

 9mm; of telson, 7; of the four longer antennular, flagella from

 flagella from base of stalk, 10; length of stalk, 4; antennal scale, 

 8.5, length of second leg, 18.5 mm ; chela, 5 ; carpus, 4.5 ; merus,

This species is nearly colorless and transparent when living, and 

 not very easy to see when swimming. Common at Bermuda, in 

 1898. It occurred in schools close to the shore and around 

 wharves. It was also in the early collections of J. M. Jones. It 

 is widely distributed in the warmer parts of nearly all the oceans.
