a total of over ninty thousand. The accompanying sketches show 
firstly the general disposition of the teeth upon the lingual ribbon, 
as viewed under a 2-inch lens, then the structure of the individual 
teeth as demonstrated by -|th power. 
Of the genitalia the penis sac is subcylindrical, performing a 
half revolution at its apex, from which is continued a narrow 
tube containing the spermatophore at its junction with the 
vas deferens, and terminating in a flagellum. The genital 
bladder is small, seated on a short duct which communicates with 
the vagina near the common orifice.
