This Palseozoic Phyllopod was first noticed and named by Mr. J. W. Salter. 

 It is a somewhat shrimp-Uke form, allied to the living Nehalia and the Silurian 

 Ceratioca;r!s. The carapace is simply bent on the back, so as to form two 

 subtriangular lateral flaps or attached valves. Several (eight or nine) abdominal 

 segments are exposed, ending with six delicate, tapering caudal appendages. Its 

 generic characters are recognised in a detailed description of its one best-known 

 species.
