of the Genera of the Araneae. 61 



De Geer, t. vii. p. 251 ; Clerck, |)l. iii. fig. 1 ; Lister, t. xix. 

 fig. 19. 



Both these species are congeneric, but in 1810 Latreillo 

 selected as the type of the genua '* Araign^e renversde 

 sauvage," De Geer, which is identical with A. triangularis^ 

 Clerck. 



Type, Linyphia triangularis (Clerck), 1757. 



TETliAGNATHA, Latreille, 1804, Nouv. Diet. xxiv. p. 135, 

 col. 1, line 5. 



One species only was included under " Les Spiraliformes " 

 by Walckenaer, Faun. Par. p. 203, namely Aranea extensa, 

 Fabr. p. 407. 1. 



Type, Tetragnatha extensa (Linn.), 1758. 



Araneus, Clerck, Svenska Spindlur, 1757, p. 22^ &c. 



This genus includes sixty-seven species, which were first 

 split up by Latreille in 1804, Nouv. Diet. p. 135, col. 1, 

 line 8. 



Under Aranea Latreille places three species only, thus 

 limiting the genus to (1) A. clavipes, Fabr., (2) A. diade- 

 mata, Clerck, (3) A. spinosa, Fabr. 



Neither the first nor the third species, however, nor any 

 species congeneric with them, was originally included in the 

 genus by Clerck, and therefore A. diadematuSj Clerck, alone 

 can be the type. 



Latreille had no power or right to select A. domestica, 

 Fabr., as the type of the genus Araigu6e, Aranea, or A. dia- 

 dema, Linn., the type of Epeira, Walck., as he does in his 

 selections of 1810, having already himself, in 1804, limited 

 the genus to one species only, A. diadematuSy Clerck. 



Type, Araneus diadematus, Clerck, 1757. 



Heteropoda, Latreille, 1804, Nouv. Diet. xxiv. p. 135, col. 1, 

 line 36. 



Under this genus are included " Les Cordiformes " of 

 Walckenaer, Faun. Par. torn. ii. p. 227 (1802), witii Aranea 

 venatoria, Linn., in addition, and anotiier species bearing no 

 name. 



" Les Cordiformes " include twenty species : — Aranea ob- 

 longa, argentata, rhombuica, pigra, bilineata, aureola, cespitum, 

 tigrina, truncata, emarginata, rotundata, Jloricola, violacea, 

 cilreo, calycina, cristata, fucnta, dauci, diana, and delicatula. 



The genus was first broken up by Walckenaer in the
