On the probable Existence of Accessory Eyes in a Fish. 
By Prof. R. LeucKkart. 
It has long been known that the bodies of certain Scopelinide are 
covered with very brilliant pigment-spots, grouped more or less regu- 
larly. Hitherto these spots had not been carefully examined; but 
Professor Leuckart, having investigated them anatomically in one 
species (Chauliodus Sloanz), endeavours to interpret them as acces- 
sory visual organs. This would certainly be a very unexpected dis- 
covery in a Vertebrate animal, especially as the number of these eyes 
amounts to more than a thousand, disseminated partly upon the 
hyoid and its dependencies, and partly on the head and belly, where 
they form two parallel longitudinal rows. Professor Leuckart’s 
opinion is founded upon the anatomical structure of the organs in 
question. They are in the form of small cylinders, the anterior half 
of which is occupied by a spherical body very like a crystalline lens. 
Behind this there is a sort of vitreous body. The layer of pigment 
which envelopes this supposed ocular bulb presents a silvery lustre 
and a structure identical with that which lines the eyes of the Pla- 
giostomi. It has, however, been impossible to detect on the nerve 
of the organ any membranous expansion acting the part of a retina ; 
but it must not be forgotten that the observations were made upon 
an animal preserved in spirits. The genus Stomias presents exactly 
similar organs. This genus has hitherto been placed among the 
Esocida, but erroneously, according to Leuckart: it must be united 
with the Scopelinide.—Bericht Versamml. deutsch. Naturf. und
