Grube, in his description of this species, distinctly says, 

 " eyes four." In his description of " P. debilis,'" he affirms it 



* Quatrefages, in the definition of this genus, says, " Caput oculis destitu- 

 tum." Savigny distinctly assigns two eyes as a generic character ; and Audouin 

 and M.-Edwards, in their ' Littoral de la France,' distinctly affirm the existence 

 of a similar number, and represent the species P. aurifera as possessing two of 

 Ihese organs. M.-Edwards gives a similar representation of them in the figure 

 he gives of this same species in Crochard's edition of Cuvier's ' Regne Aninjal.'
