The first binomial valid name given to this species is that of Gnielin. 

 The name ungula, applied by Ketzius to an unidentifiable figure in 

 Gualtieri, is earlier, but the figure is not only unidentifiable but 

 bears not the slightest resemblance to the present species. 



The specimen received from Ancey was labeled by him Argiope 

 cordata and said to have been collected by Marshall. That it really 

 came from Guadeloupe may well be questioned. The specimens are 

 identical with the Mediterranean form. The usual variations in the 

 number of ribs, convexity and lateral extension, run through the 

 series above enumerated.
