1894, Orville L Simmons, XXX.—Development of the lungs of spiders, page n72 more examples
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.
1878, Royal Microscopical Society (Great Britain), Journal of the Royal Microscopical Society, page 200From 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.
1895, Crosses W. H, The Annals And Magazine Of Natural History (sixth Series) Vol-xvi, page 142
