Synoptic Collection. 
Miss J. M. Arms has continued her work on this collection and 
is gradually bringing it into its final shape. Progress is neces- 
sarily slow since it is the preparation of a general exposition of the 
natural relations of forms in the animal kingdom and the work 
involves the selection and judicious exhibition of such obvious 
facts as can be advantageously used to prove the truth of the plan 
of classification. This, although necessarily for the most part a 
compilation, is also original work in so far as the treatment and 
arrangement of the results are concerned and therefore consumes 
a large amount of time. 
The descriptive text on the Protozoa has been finished. It con- 
sists of 108 pages and is illustrated by 217 figures drawn by Miss 
Martin, 181 of these figures are new while the remainder, which 
were previously in the collection, have been redrawn. The 
new figures, representing 32 species, are distributed among the 
classes of Protozoa as follows: Monera 18, Amoebina 44, Foram- 
inifera 37, Heliozoa 6, Radiolaria 13, Infusoria 63. 
The following specimens of Foraminif era have been mounted by 
Miss Arms for the collection : Orbiculina adunca showing the 
spiral and annular mode of growth, Nodosaria soluta, Globi- 
gerina ooze, Globigerina rubra, Orbulina universa, the same 
showing Globigerina-like shells in the interior, and Polycystines 
from the Radiolarian marl of Barbados. 
Specimens of the species of Peneroplis, found in the Bailey col- 
lection, and finely illustrating the spiral and rectilineal mode of 
growth, have been selected and mounted for the collection by 
Mrs. E. D. Ramsay. 
The descriptive text on the Mesozoa has been written, and a 
plan for the arrangement of the Porifera, according to the prin- 
ciples of a natural classification, has been made, and descriptive 
text on the calcareous, silicious, and horny sjDonges has been in 
part prepared by Miss Arms. 
Microscopic preparations of spicules of the following genera 
have been mounted and given to the Society by Mrs. E. D. Ram- 
say : Hyalonetna, Euplectella, Geodia, Suberites, Cliona, Spon- 
gilla, Chalina. 
Specimens of the silicious skeleton of Tethya, and the stato- 
blasts and spicules of Spongilla, have been selected and transferred 
from the Bailey collection to the Synoptic collection.
