On the Phosphorescence of Marine Invertebrata. 195 
thusiasm the magnificent spectacle presented by shoals of Pyros- 
omas, which in the dark look like streams of fused metal. en- 
derson ascribed the light of the gulf of Guinea principally to the 
Scyllari_ and to Salpas.* Certain Acalephs, Mollusca, Crustacea, 
Annelids, Rotatoria, Lumbrici, Turbellariz, Echinoderms, Zo- 
ophytes and Infusoria have been successively pointed out as 
capable ophosphorescence ; and if we do not here go into more 
detail on this point, it is because the subject has been so fully 
treated by Ehrenberg. In the work which the illustrious Secre- 
tary of the Berlin Academy has devoted to the phosphorescence 
of the sea, he has enumerated 450 authors who have treated 
more or less fully pf the production of light by organized beings ; 
to this memoir we refer those readers who are curious to un- 
derstand thoroughly the history of the question.t We annex a 
table, cited almost’ entire from M. Van Beneden, in which are 
numerated the various species of invertebrate animals whose 
phosphorescence has been established.
