Monendum tamen puto, nullum horum auctorum, si Caram atque Meckelvm exceperis, licet exactam Astaci dederint speciei externae descriptionem, internam naturam singularis huius sceleti penitus de- texisse, et nexum atque originem singularum huius sceleti partium gene- tice demonstrasse; sicuti in universum nullam accuratiorem expositio- nem invenire potui, quae formationem articulationem in evertebratis de- monstret; nam quod Stravss-Dverkheim9) commemoravit tantum spe- ciem fortuitam externam tangit neque veram naturam rei ipsius demonstrat- 1) Insekten- Belustigungen (Nurnberg 1755. 4.) 3.
