In this important work Leydig describes and figures the arrangement 
I of the so-called “ eye-like ” organs in the following species : — Gonostoma 
I denudaium, Raf., Ichthyococcus ovatm (Cocco), poweriw (Cocco), Argyro- 
I pdecus liemigymnus (Cocco), Scopelus rissoi, Cocco, humholdti, Risso, 
j benoiti, Cocco, honapartii^ C. & V., rafinesquu^ C. & V., and ? metopo- 
i clamjnis, Cocco. 
j The author’s conclusions are : — 
1. In certain Fishes, particular organs are arranged so as to resemble 
the organs of the lateral line.
