It is in some respects fortunate that, so far, nothing has 

 been written about these puzzling annelids in English, save by 

 Southern and myself. We are thereby saved a great deal of 

 confusion, and our British records can now be made in a satis- 

 factory manner. As I j^m. engaged on a Monograph of British 

 Oligochsets for the Bay Society, I should be greatly obliged if 

 readers would send me specimens of white worms, earthworms, 

 or waterworms from different localities. Address : 110, Wilmot 

 Eoad, Swadlincote, Burton-on-Trent. 



Addendum. — Since the foregoing was sent to press I have 

 found a further species of Henlea, which agrees in so many 

 particulars with H. tenella, Eisen, mentioned on p. 467, that I 

 record it provisionally under that name. There are three dorsal 

 and four to five ventral setae. The ces.ophagus widens in segment 

 eight, and the nerve ganglia are enlarged in front. Eisen's 

 description does not allude to the presence of a row of vacuoles 

 or glandular cells, such as I find in each segment just in front 

 of the setse. The brain is mobile, but agrees with Eisen's notes. 

 As the Continental authorities have recently added several new 

 species, and given fuller details, it is possible that the new record 

 may eventually be found to agree with one or other of these. 

 Locality: Acresford, Ashby-de-la-Zouch, Nov. 28th, 1911.
