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

 It is a somewhat shrimp-like form, allied to the living Nebalia and the Silurian 

 Ceratiocaris. 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.
