Male, — The bursa of the male is completely closed^ but 

 possesses a long dorsal lobe. In addition to this and i\\Q

The main trunk o£ the dorsal ray is exceedingly stout and 

 rather short. The externo-dorsal rays are detached at a wide 

 angle and recurve towards the dorsal side of the bursa. At 

 about 0*2 mm. behind the point of origin of the externo- 

 dorsal rays a pair of stout branches leaves the main trunk. 

 Each of these, soon after leaving the main trunk, divides into 

 two slender branches, of which the outer is distinctly the 

 shorter. Just behind this point the main trunk divides into
