SPECTROSCOPIC INVESTIGATION OF ANIMAL SUBSTANCES. 113 
Henleyi, A. Chiltensis, Cardinia attenuata, and ©. elongata were found with 
the corals. 
Montlivaltia Victorie, Duncan. This coral grows to a height of five inches, 
and may be two inches broad; it is the largest simple secondary form, and 
has the epithecal wall so peculiar to the Liassic Monilivaltie. Its septal 
number is very great, and the endotheca is highly developed, It is very 
variable in shape. 
There are some fragmentary corals in the Marlstone, but their genera are 
doubtful; and the cast of a Montlivaltia was found by Mr. Charles Moore at 
Wells, but I cannot determine the species. 
Corals from the Upper Lias. 
The only species is that which was found years since, and which was 
described by MM. Milne-Edwards and Jules Haime, Thecocyathus Mooret,

Total number of Species of Corals from the British Liassie Strata." 
Lower Lias .... 64 species. 
Middle Lias.... 2 ,, 
Upper! Ties 3. is tks 
67 species. 
The descriptions and drawings of sixty-six of these species are in my 
‘Monograph of the Liassic Corals,’ 1867, 1868, Pal. Soc. 
The TLhecocyathus Moorei, Kd. & H., was described and drawn in the 
‘Monog. Oolitic Corals, by Milne-Edwards and Jules Haime, Pal. Soc. 
Report of a Committee appointed to investigate Animal Substances 
with the Spectroscope. By HK. Ray Lanxester. 
Dunine the year attempts have been made to obtain a supply of Sipho- 
nostoma or Sabelle for the purpose of investigating the derivatives of the 
body described by me last year as chlorocruorine ; at present a sufficient 
supply has not been obtained. The absorption-spectrum of chlorocruorine 
from Sabella, however, has been carefully observed and recorded. The 
Sponge-chlorophyll has been investigated with the object of determining 
which of the two green and two yellow bodies, spoken of by Professor Stokes 
as being present in plants, is present in the sponge; and some interesting 
results appear likely to be obtained when the history of plant-chlorophyll is 
more fully known. 
The feathers of twenty-two species of birds, mostly red, green, or blue, have 
been examined for absorption-spectra; none was obtained; but Prof. Church 
has discovered a red matter containing copper in the feathers of the Turacou; 
and to this body he gives the name turacin. The spectrum of this substance 
Ihave carefully examined and recorded. As stated by Prof. Church, it gives 
two absorption-bands, when in the feather, close to those of hemoglobin, but 
readily separable from them, and by no means indicating anything like 
identity in the bodies, as Prof. Church appears to haye thought.
