tunate in not meeting with a larger number of these 

 colouring matters yielding characteristic banded spectra. 

 One of the most striking results of the present series of 

 observations is the comparatively large number of animal 

 coloured bodies yielding banded spectra which have been met 

 Avith. It must, however, be remembered that in the present 

 instance also a very large number of animal colouring matters 

 occurring in animals of most various kinds spread over the 

 greater part of the world have been passed in review with 

 a very large proportion of negative results, and that the 

 results here published represent the fruit of work extend- 

 ing over a period of three years and a half. 



Professor Lankester in his paper on Blue Stentorin above 

 cited^ enumerates the few animal colouring matters known 

 at the time of the publication of his paper to yield banded 

 spectra. The list must now be more than doubled, and should 

 stand thus : 



Htemoglobin (for its distribution see Lankester, * Proc. 

 Royal Soc,' No. 140, 1873). 



Chlorocruorin (Lankester, ' Quart. Journ. Micro. Science,' 

 Nov., 1867, ' Journal of Anat. and Physiol.,' vol. iv.) 



Bonellein (Sorby, ' Quart. Journ. Micro. Science,' vol. xv, 

 166). 



Bile-pigments and derivatives. 



Chlorophylloid substances (in Spongilla fluviatilis, Sorby, 

 'Quart. Journ. Micro. Science,' vol. xv, p. 7). 



Turacin (A. H. Church, 'Phil. Trans. S. Soc.,' 1869, 

 p. 627). 



Aphidein and allies (Sorby, ' Quart. Journ. Micro. 

 Science,' vol. xi). 



Actiniochrome, from Bunodes crassicornis (H. N. Moseley, 

 ' Quart. Journ. Micro. Science,' vol. xiii, p. 143, 1873). 



Blue stentorin (Lankester, ibid., p. 139). 



Pigment of Odax and Labricthys (fish) (George Francis, 

 of Adelaide, ' Nature,' p. 167, Dec. 30th, 1875). 



Polyperythrin. 



Red colouring of Ccenopsammia. 



Two distinct colouring matters in Adamsia sp. 



Purple pentacrinin. 



Red pentacrinin.
