49G Mr. C. R. Nanijana Eao on the Anatomy of 



an inch in diameter and only 6 inches high. The writer was 

 looking for a tough stout specimen 8 inches high and 1| inch 

 ilii'-k. 



Gray had not noticed that at one of the tapering and 

 rounded ends there was a contracted opening with well- 

 defined margins that could easily be stretched several 

 millimetres. 



The writer failed to find the axial stem of sea-weed; but 

 there can hardly be any doubt that it has existed, and 

 possibly it still exists, but there is no need to mutilate the 

 specimen to find it. 



A dissection of one of the polyps showed four folds in the 

 branchial sac, and gonads only on the right side of the body. 

 (The writer only found two gonads, but one may have been 

 lost in removing the ascidiozooid from the very tough test.) 

 Accordingly, llartnieyer's identification of his specimens 

 collected near Freniantle is fully confirmed by comparison 

 with the recovered type. 



L. — On the Anatomy of some new Species of Drawida.

[Plates XV.-XVllI,] 



The adult anatomy of this genus of 01igoch?ete worms is 

 uovv fairly well established, especially by the investigations 

 of authors like Beddard, Ben ham, Bourne, Michaelsen, 

 Perrier, Rosa, and Stephenson. The present communication 

 deals with certain glands associated with the reproductive 

 apparatus of some new species of Draioida not hitherto 

 recorded so far as I am aware. The material at my disposal 

 has been a large collection of well-preserved worms collected 

 towards the middle of 1918 in the rain-forests of Coorg, at 

 elevations ranging from 2500 feet to 4000 feet. I do not 

 propose to add any remarks on the known species contained 

 in my collection, but will select for discussion the forms 

 hitherto undescribed, I have received from Dr. Stephenson 

 and Dr. Michaelsen, copies of their excellent papers relating 

 chiefly to those forms occurring in Ceylon and the Indian 

 Empire, and my thanks are due to them and also to Dr. N. 

 Aunandale, who courteously permitted me in June 1919 to 

 examine the named collection of the Oligocha^te worms 

 belonging to the Zoological Survey of India.
