 Beddard, ' Quart. Journ. Micr. Sci./ xxx. 



Genus 14. Teleudrilus, E-osa, 1888. 



The eight setse, in couples, are rather far apart. 



The clitellum includes Somites xiv — xvii. 



The male pore is median on Somite xix ; the pair of 

 oviducal pores between Somites xiv and xv; a median 

 spermathecal pore between Somites xiii and xiv. 



Nephridiopores in line with outer setse. 



The testes in Somites x and xi, enclosed in a sac-like con- 

 tinuations of the sperm-sacs, which lie in Somites xi and xii. 

 The ciliated rosettes are in the latter somites. 



The two prostates open into a median copulatory sac, 

 communicating with the exterior and receiving another 

 median sac. 



The ovary is continuous with the wall of the ovisac, into 

 which the funnel of the oviduct opens. There is a commu- 

 nication betw^een the ovisac and the neck of the spermatheca 

 on each side. 



[The gizzard occupies Somites vi and vii (? also v) ; there is 

 a pair of lobed calciferous diverticula in Somite xiii, and 

 ventral diverticula in ix, x, xi. 



Nephridia simple, as in Eudrilus.] 



Species 1. T. raggazii, Rosa, 1888; Africa. 



See Rosa, 'Ann. d. Mus. Civico del Storia Nat. d. Genova,' 

 Series 3, vi, 1888. 



Genus 15. Pontodrilus, E. P., 1881. 

 The eight setse are separate. 

 The clitellum, which is complete, occupies Somites xiii to 



XVII. 



The male pores in Somite xviii. 

 The prostate is tubular and convoluted. 

 Sperm-sacs. — Two pairs, in xi andxii. Testes and funnels 

 in IX, X. Ovary and oviduct as usual.
