ANNELIDS. I 



then I agree perfectly with him, but when he adds a little later: „Dagegen ist es ohne Zweifel 

 rich tig, eiue Gattung wie Antinoc, mit der Art Antinoe Sarsi Kinberg 1862 als Typus aufzustellen 

 weil hier ein ganz neuer Typus von Neuropodialborsten hinzukommt", I do not know whether he is 

 right or not. I am most inclined to urge that the author in these words is laying too much stress on 

 the shape of the neuropodial sete which, in the whole, vary very much within the group under 

 consideration. 



On the following pages twentynine species of the genus Harmothoe are dealt with. 



As to the genus Lepidonotus I shall first point out the peculiar shape of the eerjhalic lobe, 

 the two frontal prominences of which are continued in the paired tentacles, a type of head which this 

 genus has in common with some other genera, viz. the genus Alentia, the genus Drieschia and the 

 new genus Bathynoe\ established in this paper. Whether all the forms with the cephalic lobe of the 

 Lepidonote type will prove to form a natural group or not I have no decided opinion at present 



A junction of Lepidonotus and Gattyana in one genus, such as Levinsen was inclined to make, 

 I find entirely unjustified; on the other hand I find it unnecessary to discuss this view, as I believe it 

 has scarcely any other follower among specialists. According to my opinion the genus Gattyana is much 

 closer related to the genus Harmothoe than to Lepidonotus. We have thus the species Harmothoe 

 villosa which evidently represents a transitional form between these two genera. But this question is 

 discussed later on under the species under consideration. 



The new genus Batliynoe is closely allied to the genus Lepidonotus, but must be maintained 

 as a special genus. It is a deep-sea form of great interest.
