 Of this genus an excellent little monog-raph was published by 

 Dr. J, E- Benedict in 1897. He assigns to it fifteen species, and 

 gives figures of the thirteen which had come under his own 

 observation- The genus may be defined as follows: — 



Sides of head in a dorsal view entire and not laterally produced. 

 Side-plates of perason coalesced with the segments. Pleon con- 

 sisting of a single segment, with c ne pair of lateral sutures at the 

 base. Eyes lateral- Second antennas with well developed multi- 

 articulate tidgellum. Alaxillipeds with thrte-jun l d palp, 

 or in other words, maxillipeds five-jointed. Uropods with a 

 sinele b'-anch. 



Dr. Benedict distinguishes two sections of the genus, the first 

 having the distal end of the pleon emarglnate or bicuspid, the 

 second having the end bluntly pointed. 



Miss Richardson, in her aralytical key to the genera of 

 Idotcidae, assigns to the group including Synidotea the character 

 of having the 'Scgs all ambulator}-" In 5". Jiirtipcs, however, the 

 first pair are shorter and stouter than the rest, with expanded 

 penultimate joint and reflexible finger constituting a prehensile 

 hand. Also they close so firmly upon the mouth that their amibu- 

 latory function lias probably been relinquished-

 On the description given by Miers, and quoted by Benedict, 

 little criticism is needed, but IMiers says- without reserve, that 

 the legs are long and sleiidcr, whereas the fir^t pair are rather 

 short and stout." Also he speaks of the distal emargination in the 

 telsonic se£i-ment as small an«l shallow. It seems to be variable..
