Onifcus, A P T E R A. 259 



Genus XII. Oniscus. 

 Linn. Syft. Nat. page 1069* 



The Onifcus has fourteen feet. 

 The antennas are fetaceous, and 



The body of an oval form. 



Geoffroy adds to the above characters of the 

 Onifcus, that the antennae are bent. He has fe- 

 parated the Onifc. Aquaticus^ Linn. Syft. Nat. 

 No. 1 r, from the other fpecies, under the gene- 

 rical name of Jfellus, on account of the number 

 of antennas in that infect, which are four ; two 

 of thefe are longer than the others, but they 

 are all bent : he obferves that the head, in both 

 thefe genera, is intimately joined to the thorax. 



Schseffer has followed Geoffroy in this divi- 

 fion of the Linnaean genus, and obferves, that 

 the feet of the Afellus are made for running, 

 that the body is oblong, and the mouth furnifli- 

 ed with two palpi.
