286 PROCEEDINGS OF THE ACADEMY OF _ [Nov.—Dec., 
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. 1a, b,), 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:
