NEW ENCHYTRMID WORM FROM INDIA. 799 



dorsal pores, it is clear that the present species cannot be safely referred to the 

 ^enus Fridericia, which is so distinctly characterised by the peculiar paired 

 character of its setae. There remains only Henlea and Bryodrilus, from which, 

 however, the species described in the present paper differs in several points. 

 With genera described more recently than those included in Michaelsen's 

 •omprehensive work just quoted, e.g. Hydrenchylraus%, I cannot identify this 

 semiparasitic Enchytraeid from India. 



It is true that four species, vis., Marionina glandulosa, Enchytrceus minimus, 

 E. parvulus §, and E. turicensis, possess, as does the species dealt with here, two 

 setae in each lateral, and three in each ventral bundle ; but I do not regard 

 those European species as identical with the present Indian form. 



In the meantime I place the species in the genus Henlea, where the charac- 

 teristic glandular pouches of the gut are occasionally absent (e.g. Henlea 

 dichsoni), in default of living material and a more exhaustive examination. I 

 propose to name it after Mr. Lefroy, who first directed attention to the species.

 permit of any certainty.
