LAMELLISABELLA ZACHSI 



427 



The highly flattened spermatophores form rectangular plates with parallel 

 sides, suddenly tapering to a point at the filamentar end (Fig. 165C). The 

 base of the filament is a broad, flat triangle, bent down parallel to one of the 

 flat sides of the spermatophore. It then tapers rapidly into the very slender 

 and extraordinarily long filament, which forms a characteristic horseshoe- 

 shaped skein, fitting closely on to the flat surface of the spermatophore. The 

 sperm may be seen to lie within the spermatophore in two longitudinal rows, 

 orientated with axis across the rows. The spermatophores are 1 mm long and 

 0-45 mm across.
