172 ARACHNIDES. 



we still presume that these latter Araneides and other large 

 species which weave no web, as also the Galeodes and Solpu- 

 gse, are the animals they collectively designated by that name, 

 and of which they distinguished several species. Such also 

 was the opinion of Mouffet, who, in his Theat. Insect., p. 

 219, has figured a Lycosa or Mygale, of the island of Can- 

 dia, as a species of Phalangium. 



Lister was the first and most successful observer of the 

 Spiders, whose habits he was enabled to study ; those of Great 

 Britain laid the foundations of a natural arrangement, of which 

 most of those that have been since published are mere modi- 

 fications. The more pecent discovery of species peculiar to 

 hot climates, such as the Jlraignee maponne described by the 

 abbe Sauvages, and some others, the use of the organs of man- 

 ducation introduced into the system by Fabricius, a more 

 exact study of the general disposition of the eyes, and of their 

 respective sizes, with that of the relative length of the legs, 

 have all contributed to extend this classification. Walck- 

 enaer has entered into the most minute of these details, and it 

 would be a difficult matter to discover a species that could not 

 find its place in some one of his divisions. One character, 

 however, existed, the application of which had not been made 

 general : I allude to the presence or absence of the third ter- 

 minal hook of the tarsi. Savigny, so far as this is concerned, 

 has given us a new method, of which, however, I have only 

 seen a simple sketch(l).

We knew nothing of the observations of M. Savigny on the Spiders, which ac- 

 company the plates of Nat. Hist, of the great work on Egypt, until long after our 

 article relative to the same animals was printed. 



That gentleman Hist. Nat. ut sup. establishes the following genera in the 

 .family of the Araneides: 1. Ariadne, near that of Segestria, having but six eyes, 

 of which the two intermediate posterior ones are further forwards; 2. Lachesis, 

 near Drassus, but with the hooks of the Chelicerae, {forcipules, Savign.,) very 

 small; 3. Ehigone, also allied to Drassus as well as to Clubiona; thorax very high 

 before; second joint of the palpi spinous, and dilated into angle or tooth at the 

 extremity; 4. Hersilia, allied to Agelena and Theridion of Walckenaer; feet 

 long and slender, the superior nails bidentate; eyes united on an eminence, ar- 

 ranged in two transverse lines, and curved backwards; two very long fusi
