1. Preliminary Note upon Heliodrilus, a new genus of Eudrilidae. 



By F. E. Beddard, M.A., London. 



eingeg. 30. September 1890. 



This genus hears some ressemhlance to Hyperiodrilus which I have 

 briefly described in a recent number of this Journal, and it inhabits 

 the same locality, viz: Lagos, W^est Africa. 



The setae have the same arrangement and the diteli um appears 

 to occupy about the same number of segments. 



The male generative aperture is median and unpaired and 

 lies upon the XVII. segment. 



On the X. to the XVI. segment inclusive are a series of sucker- 

 like structures one to each segment. The last three of these are median 

 in position; the three anterior lie to the right of the middle line. 



The ovi ducal pores lie upon the XIV. segment in front of the 

 lateral setae. 



The integument has the same peculiar bodies which I have de- 

 scribed in Eudrihis ' ; they are scattered irregularly and are present on 

 all the segments except the first. 



The alimentary tract has no anteriorly situated gizzard but 

 6 gizzards — one to a segment — at the junction of the oesophagus 

 with the intestine. In each of segments IX, X, and XI is a ventral 

 oesophageal pouch (»Chylustasche« Michaelsen) which have the same 

 structure as in Hyperiodrilus; this however only applies to the last two;
