on the septa in the quite immature Goniada (12, Part II, 

 PI. 35, fig. 33), or in the Phyllodocids. In these worms, as 

 in Syllids, the rudiments of the genital funnels in some of 

 the anterior segments amount to merely a few cells gathered 

 together just above the point where the nephridium is at- 

 tached to the septum. 



No further development is undergone by the rudiment of 

 the genital funnel (in the non-reproductive segments) in such 

 forms as Haplosyllis, where ripe genital products are only 

 stored in the posterior reproductive buds; but in a mature 

 Pionosyllis, for instance, every stage is found, on passing from 

 before backwards, between a nephridial funnel to which the 

 coelomic epithelium appears to have contributed but little, and 

 the more posterior perfectly developed genital funnels which 

 have entirely superseded the nephrostomes (figs. 21 and 35).

This account of the excretory organs of the Amphinomidae 

 is based chiefly on an examination of sections of Euphrosyne 

 foliosa, Aud. and Ed., from the coast of Normandy, and 

 Eurythoe sp., from Ceylon. 



Ehlers (6), describing the nephridia of Euphrosyne 

 racemosa, says : " Die Segmentalorgaue finden sich fast in 

 alien Korperringen,. deun ich sah sie ohne Unterbrechung bis 

 im zwanzigsteu Segmente. Sie liegen dort paarweise in 

 jedem zunachst unter der Riickenoberflache, mit ihrer ausseren 

 Miindung am medianen Rande des Kiemeubesatzes. Jedes 

 dieser Organe ist eine langgestreckte zweischenklige Rohre, 

 die vom Aufhangepunct an der ausseren Miindung sich unter 

 der Riickenwand nach hinten wendet und wohl zwei oder 

 drei Segmente durchzieht. . . Weder an den Miindungennoch 

 im Lichten der Rohre habe ich Flimmerung gesehen " (p. 78). 



I must confess that I am quite unable to confirm this 

 author's extraordinary account, aud am driven to the conclu- 



' Since I hope some day to be able to publish a description of the anatomy 

 of a large Amphinomid I obtained in Ceylon, the structure of the excretory 

 organs in this family will be only very briefly dealt with in this paper.
