quite marked from others. I hope later to deal at further length 

 with the nephridia when I have obtained other species for com- 

 parison. 



As far as I can make out at present, the nephridia in this 

 species are evidently disappearing; and in this feature, coupled 

 with the fact that the so-called " excretophore " cells are very 

 large and exceedingly abundant in the organism, lends some 

 special interest to the question. 



Blood- system — The blood-s} 7 stem of Glossiphonia has been so 

 thoroughly worked out by Oka, that very little can now be 

 added to our knowledge of that system. In general arrange- 

 ment the system in this species agrees very closely with that in 

 other species of the same genus. One conspicuous feature is the 

 very well developed channels in connection with the diverticula 

 of the stomach. As already stated, the intimate relation of these 

 vessels with the diverticula of the stomach seems to point to the 

 conclusion that the stomach functions in connection with diges- 

 tion and absorption. 



Glossiphonia inflexa, sp.nov. 



A single specimen of this species was obtained by Mr. H. L. 

 Kesteven near Waverley, Sydney. 



The body is broad and flat, and of a pale sage-green colour. 

 It is semitranslucent. The marginal portion of the body is very 

 thin, and in the preserved specimen folded under the ventral 

 surface. 



The length in an unextended condition is 14 mm., the breadth 

 4*5 mm. 



The surface is very smooth, and the annulations are not very 

 distinct, except near the margins of the body, and at the anterior 

 extremity. The total number of annuli is seventy. 



No eyes are present, and sense papillae are present only in the 

 middle body-region, where they occur on every third annulus. 



The anus is situated on the dorsal surface of the last annulus, 

 and has a much folded contour.
