NUMBER OF SPECIES OF INSECTS. _Page_ 193.

Professor Huxley mentions that "Gerstsæcker in the new edition of Broun's 'Thier-Reich' gives 200,000 as the total number of species of _Arthropoda_." In this connection Mr. McLauchlan, when claiming that there are 200,000 species of Insects, adds, "In one order alone (_Coleoptera_) it is estimated that 80,000 species have been described."--_Nature_, xv. p. 275.
