He records a Pulex cancriforniis or Cancer inacrourus rufescens, which is found under stones on 

 the beach or in the stomachs of fish. Further, he gives in plate i. figs. 12-13, a very

 antennia brevissimis, corpore latiore, and states that it is found on large Meduste (Boeck).

Scopoli changes the Linnaean name Aptera into Pedestria for his seventh order. He defines 

 Ca7ice)- thus : " Palpi (2) chelati. Oculi (2). Cauda inermis," and names the species numbered

 Bernhardus, Diogenes, Istrianus, Nutrix, Cruentatus, Ma7iiis, Locusta, Pulex. The last
