Description:
The penis-stilette is a greatly curved funnel which extends from a very broad, deeply indented base and suffers two changes of direction-one a half circle and the other a right angle bend at which point by a gradual reduction the genital canal terminates in a very sharp point. The external opening is terminal and oval in shape and is formed by an angular truncation of that part of the stilette. The sperm-cells possess a tactile feeler, an undulating midbody provided with two short setae, and a highly vibratile tail region. The setae appear early. A longitudinal row of chromatin granules extends from the origin of the lateroposterior pair of setae. p. 24
