JBihliograpliical History. — Baker is said to be the first 

 author who has taken any notice of any of the animals of 

 this family. In his work, ' Employment for the Micro- 

 scope,' 1753, an anonymous correspondent describes at 

 some length an insect which has a bivalve shell, somewhat 

 resembling a small fresh-Avater mussel, and gives a figure 

 of it lying on its back, which is barely sufficient to enable 

 us to discern that it is a Cypris. 



Straus complains that he cannot discover any mention 

 made of the genus by Baker, either in the edition of 

 1743 or 1744, which are the only editions he has been 

 able to see ; neither is there, he says, any plate 1 5 in either 

 of these editions. He quotes the wTong work, however, 

 having referred to the ' Microscope made Easy,' instead 

 of Baker's second work, ' Employment for the Micro- 

 scope', in which he would have found the insect referred 

 to by Midler. 



Linnseus, in his 'Fauna Suecica,' 1746, describes a 

 species in a few general terms ; and, in the seventh 

 edition of the ' Systemge Natura,' 1748, he mentions a 

 species under the name of MohocuIks co?icJia pedata, but 

 gives no description. In the tenth edition of the same 

 work, 1760, he gives the description, as taken from the 

 ' Fauna Suecica,' but names it Monoculus conchaceiis. 



Joblot, in his ' Observations d'Histoire Naturelle faites 

 avec le Microscope,' 1754, describes a species, which he 

 calls pomon nomme Betouche, or Grain de Millet, from 

 its resemblance in size and colour to that species of seed, 

 and gives a figure of it.
