We believe that the above list is far from ‘complete, at least as 
regards marine animals. Our own observations enable us to ‘add 
at least two species of Polynée, one species of Syils, some sé

II. On the mode of producing light by Marine Invertebrate 
Almost all researches undertaken to discover the mann ner est 
ducing light in animals, have been made on insects, eS aly 
the Lampyri and Elaters. Spallanz nzani, Burmeister, but above 
_ all, Macaire,t have published results apparently decisive. These
