is hoped, however, that in the systematic portion of this 
study it will be possible to give the exact descriptions and 
names. 
The species of annelid found at Ringsend which gave me 
the greatest pleasure, was a pecuHar Tubificid with Pachy- 
drilus-hke setae. Full particulars will be supplied later, but 
it may here be remarked that I have found the same 
species on the east coast of England, and have been led to 
beheve that it is identical with the Lumhricus lineatus of 
the earlier authors. It is quite distinct from Lumhricillus 
lineatus, a true Enchytraeid which is found in similar 
localities. The Ringsend specimens contained at least one 
adult. It is found by digging in the moist sand, and might 
easily be mistaken for ClitclHo or one of the other estuarine 
forms of annehds. 
Enough has been said to shew that a number of additions 
will be made to the annelid fauna of Dubhn, as a result of 
my \-isit. One might hope for great things if other districts 
could be explored in the same systematic way.
