The Descent of Man and Selection in Relation to Sex, Vol. I

Note 423 — Chapter IX

Reading edition

Aug. Vinson (‘Aranéides des Iles de la Réunion,’ pl. vi. figs. 1 and 2) gives a good instance of the small size of the male in Epeira nigra. In this species, as I may add, the male is testaceous and the female black with legs banded with red. Other even more striking cases of inequality in size between the sexes have been recorded (‘Quarterly Journal of Science,’ 1868, July, p. 429); but I have not seen the original accounts.

Explore with AITake your curiosity a little further.
