After describing the parietal organ in Batrachians, Lacerta, Varanus , 
Anguis, Chalcides, and Spkenodon, and especially the two additional 
parietal “ eyes” in Anguis [discovered by M. Duval & Kalt, CR. Soc. 
Biol. (9) i, 1889, p. 85], the author sums up by stating that in his belief 
the question of the significance of this organ remains as obscure as ever ; 
a comparison with the ocelli of insects, although open to much criticism, 
appears to him not to be out of question.
