 pro\.- to be ver\ -cant\. The specimens are generally so thickly covered 

 with muddy particles adhering to the numerous curved processes of the bodv. 

 that it is rather difficult at tir*t si^ht to obtain a correct idea of their true 

 form- and wonderful armature. They move through the water in a somewhat 

 jerky manner, and ne\er lor long together.

 but wanting a sub-dorsal series. Rostrum very small, but well defined. Anterior 

 antenna' in female distinctly 4-articulate; posterior antennae about as in Anchorabolus. 

 Oral parts resembling in structure those ist the said genus; posterior maxil- 

 liped-. however, less slender. 1st pair of legs of nearly the same structure 

 as the 3 succeeding ones, inner ramus in all pairs very small and rudimentary. 

 uniarticulate. Last pair of legs without any inner expansion of the proximal 

 joint, digitiform process of this joint very slender and elongated.
