as their external anatomy is concerned^ and cannot be 

 recognised with certainty. Kinberg's genera must be relegated 

 to oblivion. 



Branch II. Meganephrica. 

 The excretory system is in the form of large, greatly coiled 

 tubes unaccompanied by a network of small tubules. Each 

 nephridium opening into the ccelom by a funnel : usually a 

 pair in each somite, though the most anterior somites may be 

 deprived of nephridia. 

 A. A prostate is present. 



a. Male pores intersegmental, immediately behind Somite 

 X or XI ; clitellum developed around this and the 

 adjacent somites. 



Family IV. Moniligastridse, Glaus, Vejdovsky Rosa (= L. 



aclitelliens, E. P.). 



Genus 13. Moniligaster, E. P., 1872. 



Setse in four couples. 



Clitellum observed in only one species (M. sapphirina- 

 oides, A. G. B.), where it occupies Somites x to xiii ; it is ill- 

 marked. 



Male pores between Somites x/xi ; or xi/xii. 



Oviducal pore on Somite xii (or xiv). 



Sperm-sacs, one pair occupying Somite xi (Horst), or ix 

 and X (Beddard). 



Ovisac in Somites xiv to xvi, or fewer somites. 



Nephridiopores in a line with the outer couple of setee. 



Prostates small, or large and tubular. 



Testes in Somite ix (Beddard). 



Spermathecse in Somite viii or ix. 



The nephridium has a long caecal prolongation of the duct 

 beyond the point at which the short slightly coiled tubule 

 enters. There is apparently no modification of the anterior 

 nephridia. 



Gizzard moniliform, four-lobed, in all or some of the Somites 

 XIII to XXII (sometimes there is an additional gizzard ante- 

 riorly).
