94 THE ZOOLOGIST. 



9. Chamcedrilus chlorophyllus, Friend. 



The last of the white Worms which I have to record is of 

 peculiar interest, because it appears up till the present entirely 

 to have escaped the observation of Continental investigators. It 

 may possibly have been found by Bretscher in Switzerland, but 

 if so his description has not been sufficiently detailed to allow of 

 its identification. I first described it (9) in 1913, but had found 

 it on many occasions previously, without being able to trace its 

 connection with any known species or genus. It is widely dis- 

 tributed in this country, and there was every reason to suppose 

 it would be found on the Continent. Found among beech-leaves 

 by the little brook in the woods between Oberbieber and Brauns- 

 berg, the Worm showed the following characters : Length, 6-8 

 mm., stretching to 10, and very slender ; segments 35-40. Setae, 

 3 per set, sigmoid. Septal glands five pairs, or four pairs with the 

 hindmost pair lobed so as to present the appearance of being 

 double. Large brown chloragogen cells and large irregular oval 

 coelomie corpuscles. Intestine yellowish. Brain about as long 

 as broad, incised behind. First nephridia behind the girdle, which 

 occupies an advanced position. 



This Worm is closely related to Bryodrilus and Buchholzia, but 

 differs in many important details alike from the one and the 

 other. 



I also found a Tuhifex, Stylodrilus, and various species of 

 LumbricidcB, none of which, however, are related to the Enchy- 

 traeids.
