    • 1878, Royal Microscopical Society (Great Britain), Journal of the Royal Microscopical Society‎[2], page 200:
      We must remember, finally, that the dipneumonous spiders can live for many months, that is to say, during the whole season of physiological activity, without food.
    • 1894, Orville L Simmons, XXX.—Development of the lungs of spiders‎[3], page n7:
      Morin (1888) * states that the lungs of the dipneumonous spiders arise in form of infoldings at the bases of the two appendages of the second abdominal segment.
    • 1895, Crosses W. H, The Annals And Magazine Of Natural History (sixth Series) Vol-xvi‎[4], page 142:
      From a morphological point of view the genus Aysha, and, indeed, the entire group of the Anyphænidæ, is of considerable interest on account of the retention by the tracheal stigma of a more primitive position than is found in most dipneumonous spiders.
