25 8 ORDER VII. Monoculus. 



(in each of his genera but, according to 

 SchserTer, they are many in number, and 

 branched. Perhaps that Author miftook the 

 antennae for feet, and indeed mod of the 

 fpecies make ufe of the antennas to fwim, 

 and likewire to leap with ; he has changed the 

 generica! name of our author to that of Bran- 

 cbipus. The Monoculi are both oviparous and 

 viviparous; they live in fragnated waters jfome of 

 them feed upon plants, others attach themfelves 

 firmly to the bodies of different filh, whofe blood 

 they fuck for their nourifhment -, they fwim, or 

 rather fpring upon the water, with great agility ; 

 they are in general very fmall, but lay an amazing 

 number of eggs-, they lofe all motion, and 

 feem to ceafe to live in fummer, when the great 

 droughts have deprived them of water, but re- 

 vive when reftored to their proper element. 



Linnaeus relates* that one fpecies of them, 

 which is of a red colour, is fometimes fo nume- 

 rous as to make the waters appear as if changed 

 into blood.
