Fig. 1. Genitalia of S. odorata. a, No. 119,032; b, penis-papilla of same 

 much enlarged; c, No. 119,035, with detail of penis-papilla; d, No. 119,034. 



The sole is tripartite in color, the side areas being somewhat darker. 

 The back and head are quite dark in most alcoholic specimens, black 

 in life, the tips of the tubercles lighter. 



The penis is small, containing a cylindric papilla with rounded 

 end, about two-thirds as long as the penis. The penial retractor is 

 inserted upon the epiphallus not far from its base. The flagellum 

 is present as a very minute but distinct bud in most of the specimens 

 opened, but in two it was not seen though looked for. In the speci- 

 men No. 119,032 (figs, la, 6,), the male organs are evidently not fully 

 developed, the penis and epiphallus being small and short, while 

 the retractor muscle is correspondingly longer, making the total 

 length about normal, the individual being of full size though not 

 adult. Measurements of the organs in mm. follow:
