The Onifcus , with a blunt ^ forked tail 
This grows to near half an inch in length, and to about half it’s length in diame¬ 
ter. The back is fomewhat rounded, the belly flat; the colour a bluifh grey : it runs 
nimbly, and, on being touched, rolls itfelf up into a kind of ball. 
It is common about old trees, and under logs of wood arid Hones, Ray calls it, 
Afeiius afininus five vulgaris; others, Millepes. 
Onifcus cauda bifida , flylis bifur cis, UlilfCt 
The Onifcus 5 with a bifid iafi and the Jlyles of it forked * 
This grows to about half an inch in length; the breadth is nearly a quarter of an 
inch; the colour a pale brownifh grey, and the whole body fo thin, that it feems 
tranfparent: there are feven joints in it, exclufively of the head and the tail, and they 
are deeply divided. The articulation at the tail is rounded, flattifh, and larger than 
any of the others, and from this there grow two ilyles, which are each of them di¬ 
vided alfo into two parts at the end: the legs are flender, and moderately long ; they 
are of a pale brown, and tranfparent: there are feven of them on each tide, and the 
hinder ones are longer than the others: the antennas confifl; each of three joints. 
It is common with us in ponds and ditches, fometimes in running waters. Authors 
call it, Afellus Aquaticus, 
Onifcus cauda obtufa integerrima. 
The Onifcus , with an obtufe , undivided tail. 
This grows to half an inch in length, and is of an oval figure * it is black all over, 
except that the edges of the fegments are whitifh, and there is on each fide a whitifli 
fpot near the hinder legs: it’s fkin is tough and glofiy $ it runs nimbly, but on the 
flighted touch it roils itfelf up into a kind of ball, and will lie motionlefs a long time : 
it’s legs are fhort, and it’s tail obtufe, and not at all divided. 
It is found about the roots of trees in damp places, but is lefs common than the 
forked-tailed kind. Ray calls it, Afellus lividus major.

three quarters of an inch long ; it is undivided, and of a fomewhat triangular figure, 
and has two convex parallel rays on it’s under fide. 
It is found in moil of the northern feas, but no where more plentifully than on 
Tome of our own coafls. I have met with it about the Yorkfhire coaft abundantly.
