! 2. In spite of this, they do not belong to the system of the lateral line, 
^ nor can they be considered as representatives of it. 
3. In their structure, they show such differences between one another, 
that they must be referred to different forms which are termed “eye- 
like,” “ pearl-like,’^ and “ luminous ” organs. 
4. The first form, though resembling the eyes of certain Invertebrates, 
cannot, on closer investigation, be considered as true eyes. 
5. The second and third forms, which are quite unlike eyes, cannot, on 
any account, be associated with these organs of sense. 
6. The structure of all these organs is such as to cause hesitation as 
to whether they have anything to do with organs of sense, as generally 
understood. 
7. On the contrary, there are reasons to believe that these organs 
should be referred to the group of pseudo- electric, or even truly electric 
apparatus. 
8. Through the “ tapetum,” these organs can incidently produce light ; 
from an observation on the living animal, it may be surmised that they 
are phosphorescent. They should consequently be considered simply 
as luminous organs, or as objects capable of producing light.
