specimen of Cellepora fusca from the ' Rattlesnake ' collection and 

 thirty or forty years old, I detected several minute tailed corpuscles, 

 which can scarcely be any thing else than spermatozoa (see Plate 

 XXVI. fig. 11). ' 



EXPLANATION OF THE PLATES. 



Each square or division contains the chitinous appendages of a single species. 

 All the figures are magnified 115 diameters, and a scale =001 rnillim. is added.

Experiments with Light of different Wave-lengths. 



In one of my former papers (Linnean Journ. vol. xiv. p. 278) I 

 have given a series of experiments made on ants with light of 

 different colors, in order, if possible, to determine whether ants 

 have the power of distinguishing colors. For this purpose I 

 utilized the dislike which ants, when in their nest, have for light. 

 Not unnaturally, if a nest is uncovered, they think they are being 

 attacked, and hasten to carry their young away to a darker and, 

 as they suppose, a safer place. I satisfied myself, by hundreds of 

 experiments, that if I exposed to l^ght the greater part of a nest, 

 but left any of it covered over, the young would certainly be con-
