1889.] MR. E. MUYBRIDGE ON ANIMAL LOCOMOTION. 327 
The known species of birds of the island of Dominica are about 
60 in number, of which about 35 are Passeres, Picarize, and Psittaci. 
Of these five appear to be absolutely restricted to the island :— 
Blacicus brunneicapillus. Chrysotis augusta. 
Thalurania wagleri. bouquett. 
Chetura dominica. 
Besides these there are two peculiar subspecies, namely Mimocichla 
ardesiaca albiventris and Margarops montanus rufus. The great 
feature in the Dominican Ornis is the sole possession of two species 
of a peculiar group of large Parrots of the genus Chrysotis which is 
restricted to the Lesser Antilles, namely C. augusta and C. bouqueti. 
Of the other two known members of this group, St. Vincent has one 
(C. guildingi) and Santa Lucia one (C. versicolor). There ought to 
be a representative of this group also in Martinique, but it is not 
yet known tous. It is perhaps extinct. Besides the species and 
subspecies restricted solely to Dominica, this island has many other 
peculiar forms in common with its near neighbours of the Lesser 
Antilles. These will be found enumerated in Mr. Lawrence’s 
instructive index and analysis of the birds contained in Mr. Ober’s 
collections (Proc. U. S. N. Mus. 1878, p. 486), and in Cory’s 
‘ Birds of the West Indies.’ 
June 18, 1889. 
Prof. Flower, C.B., LL.D., F.R.S., President, in the Chair. 
The Secretary exhibited, on behalf of Mr. J. F. Green, F.Z.S., a 
very fine example of the Common Eel (Anguilla vulgaris) obtained 
from a pond at Lee, Kent, as mentioned in ‘The Field > of August 
25th, 1888. fe ay 
_ Mr. B. B. Woodward exhibited and made remarks upon a draw- 
ing of Arope caffra, a carnivorous Snail from the Cape Colony, taken 
from an example lately living in this country. 
Mr. B. B. Woodward also exhibited an example of a fossil shell 
from the Eocene of the Paris Basin, Neritina schmideliana, and a 
section showing its peculiar mode of growth. 
Mr. Eadweard Muybridge exhibited a number of projections with 
the Oxy-hydrogen Lantern. These had been selected from his ela- 
borate work on Animal Locomotion now being prepared for publication 
under the auspices of the University of Pennsylvania, and illustratea 
successive phases of motion, such as occur during a single stride of 
the walk, amble, trot, gallop, &e., of Horses, Dogs, Elephants, and 
other animals, both wild and domestic, and of birds while flying.
