 Semper Lubeckensis. 



Cette espece tres-remarquable est un exemple frappant du peu 

 de fixite du nombre, de la forme et de la disposition des denticules 

 des cuisses, dont le premier devient presque une dent. II y en ä peu 

 pres trois entre l'une de ces trois dents e l'autre, mais il est difricile 

 de les compter exactement; quelque-uns deviennent plus petits ou 

 disparaissent. La nature, dans ce caractere comme dans certains 

 autres, semble se complaire dans une ebauche, qu'elle laisse de plus 

 souvent inachevce." Sichel.
