Part V.Entelegynae (continued). Family Pholcidae. The genus Pholcius, Walck., was erected by C. Koch, in 1850, to family rank. Prior to this date, it had been included in the family Theridiidal. Simon, in his masterly work, has defined its position, and to this the student is referred. The family Pholcidae has since been divided into two subfamilies-- the Pholcinae and Ninetidinae. With the first of these, twenty genera are now associated, of which three occur in Australia; the second embraces only one (Ninetis, Sim.), and its habitat is defined as "Arabia felix."
