head and mandibles, narrowed laterally like that of many Poly- 

 desmidae, furnished with four tubercles above and covered with 

 short hairs. Tergites marked with a median longitudinal sulcus ; 

 the anterior covered part of each elevated and thickly covered 

 with fine close-set blunt granules ; the median part of the ter- 

 gites is depressed forming a transverse furrow; it appears to be 

 coarsely hairy in front ; the posterior part is elevated like the 

 anterior, it is covered with short hairs, and is furnished on each 

 side of the middle line with two transversely set low tubercles. 

 The keel arises about the middle of its lateral surface, its an- 

 terior edge is thickened and strongly upturned close to the 

 body, the anterior angle strongly rounded, the posterior acute 

 and slightly produced, the posterior border lightly concave, the 

 anterior straight or slightly convex, the edges very finely ser- 

 rate. The keels are nearly horizontal, being however slightly 

 depressed and tipped a little forwards and downwards ; at the 

 anterior end of the body they are . directed slightly forwards and 

 at the posterior end backwards. There is apparently no trace 

 of a pore, but just above the edge of each lateral border there 

 is a tubercle which bears a seta on its summit; when this seta 

 is removed its articular socket closely resembles a repugnatorial 

 pore ; below the keel the tergite is finely granular in front, 

 smooth behind, with a row of setae along the posterior border. 

 Pedal laminae free. Anal somite posteriorly rounded. The copu- 

 latory feet formed from the two pairs of the 7 '-'^ somite and 

 completely external.
