our gardens, and with which it might be useful for us to 
become better acquainted. 
The chetopoda are of no great utility to the human species. 
It appears, however, that the larger species may be made 
available in the way of food. Pallas relates that some inha- 
bitants of the coasts of Belgium eat the buccal portion or 
mouth of the aphrodita aculeata ; but this must prove a very 
poor resource indeed. 
The larger nereides, the arenicola, the clymenae, the tipun- 
culi, and even the lumbrici, are employed as baits with great 
advantage in hook or small net fishing. A tolerable number 
of fish are taken in this way alone ; and it has been remarked, 
that the fishing is more successful when these worms can be 
employed in the living state. 
These animals, notwithstanding the small number of cases 
in which they can be useful to us, are nevertheless more ad- 
vantageous than hurtful. The earth-worms themselves, by 
dividing the earth, facilitate the development of the roots of 
the plants of our gardens. 
As M. de Blainville, in his second class of worms ( cipoda ) 
has thought proper to include along with the last division of 
our author’s annelides (the abranchia asetigera ), intestinal 
worms, we cannot in this general sketch avail ourselves of his 
observations, valuable as they otherwise may be. We must 
therefore reserve what we have to say concerning these animals, 
such as Him do, &c. until we come to observe upon them in 
their proper place. We shall now proceed to consider suc- 
cessively the orders and genera of the Annelides of the text. 
We begin of course with the order 
TuBXCOLiE. 
Under the denomination of Serpul^E (our first genus), 
coming doubtless from the word Serpere , to creep, Linnaeus 
very early distinguished a pretty great number of marine
