Badly preserved. 
Badly preserved; probably botk mature 
and immature specimens present. 
Gonads destroyed, cannot be measured. 
Badly preserved; the specimens witb 
well preserved gonads have tlie sizes 
10—16 mm. 
In the small specimens gonads are 
not visible; most specimens of 10 — 
12 mm. have gonads of 1—2 mm. In 
the larger the gonads are mostly 
destroyed. 
The immature specimens are ca. 10 mm. 
in size. 
Badly preserved. 
Specimens of all sizes up to 23 mm., ver' 
badly preserved so that investigatioi 
of the gonads is impossible. 
Well preserved. 
One specimen of 14 mm. (gonads 4 mm.), 
the others 4—12 mm. 
In some specimens the gonads are just 
visible as fine points; only in 10 specim. 
(9—13 mm.) they are somewhat pro- 
longed.
