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, Picariee, and Psittaci. 

 Of these five appear to be absolutely restricted to the island : — 



Blacicus brunneicapillus. 

 Thalurania wagleri. 

 Chcetura dominica. 



Chrysotis augusta. 

 bouqueti. 



Besides these there are two peculiar subspecies, namely Mimocichia 

 ardesiaca albiventris and Margarops montanus ru/us. The great 

 feature in the Dominican Ornis is the sole possession of two species 

 of a peculiar group of large Parrots of tlie genus Chri/sofis 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 to us. 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. Cher'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 {Anr/uiUa vulgaris) obtained 

 from a pond at Lee, Kent, as mentioned in ' The Field ' of August 

 25th, 1888. 



Mr. B. B. Woodward exhibited and made remarks upon a draw- 

 ing of Mrope 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 A nimal Locomotion now being prepared for publication 

 under the auspices of the University of Pennsylvania, and illustrated 

 successive phases of motion, such as occur during a single stride of 

 the walk, arable, trot, gallop, &c., of Horses, Dogs, Elephants, and 

 other animals, both, wild and domestic, and of birds while flying.
