3. On the Spermatophores of the Earthworms of the Genus 

 Benhamia. By Frank E. Beddard, M.A., F.R.S. 



[Eeceived November 19, 1901.] 

 (Text-figures 92-94.) 



At the present moment little is known of the spermatophores 

 in this genus, except the fact that they occur in several species. 

 So far as I am aware the following is the extent of our knowledge 

 on this matter. Dr. Micbaelsen has reported upon the structure 

 of the spermatopbore of Benhamia monticola^ in the following 

 words : — "Past jede der nntersucbten Samentaschen entbielt eiiie 

 grosse Spermatophore, die den grossten Theil des Eaumes der 

 Tascbe in Anspruch nahm. Eine solchs Spermatophore hat die 

 Gestalt einer langbalsigen Karaffe. Der Bauch derselben liegt 

 in dem Hauptraum der Samentasehe, der rohrenformige Hals in 

 dem Ausflihruugsgaug. Das aussere Ende des Halses schieu bei 

 den herauspreparirten Spermatophore offen zu sein ; doch ist es 

 moglich das ein Verschluss abgefallen ist." A briefer note in the 

 same memoir concerns the spermatophore of Benhamia itiolensis.
