1893. NOTES AND COMMENTS. 329 
In regard to one of those belonging to the former genus, the describer 
observes that specimens may subsequently show a transition from 
the supposed new form to one which he has previously named S. hosei, 
in which case the former will have to be reduced to the rank of a 
variety. Nevertheless, he adds, ‘‘in the absence of such intermediate 
forms, and in view of the great constancy in the coloration of S. hoses 
already noted, it seems best to give a name to the striking variation 
from it now described.” We venture to have doubts as to the 
wisdom of this course. 
PicTURES AT BRIGHTON. 
Ir is not often that Art and Science go hand in hand, therefore 
two collections of pictures now exhibited on loan at the Brighton 
Corporation Art Gallery are of an unusually interesting and instruc- 
tive character, from a scientific point of view. The series of African 
scenes, lent by Mr. Robert White, painted in oils by Mr. Thomas 
Baines, the well-known explorer, illustrate the geology, zoology, 
botany, and ethnology of the South and West regions of that 
continent. The successive river-terraces of the Great Zambesi, and 
its winding, deep-cut, cafon-like gorge, are well depicted by the 
artist, a brother of Mr. Geddes Baines, discoverer of the Dicynodonts. 
There is a picture of the spot where remains of one of those extra- 
ordinary reptiles were first found. Miss C. F. Gordon Cumming 
exhibits a series of water-colour sketches of Ceylon and Fiji, including a 
fine set showing the river-terraces, silica-deposits, sulphur, mud, and 
hot springs of the volcanic district of New Zealand, where the whole 
aspects of the region were so completely changed by a subsequent 
convulsion of Nature, that these pictures portray scenes no longer in 
existence. The luxuriant flora of Ceylon is well illustrated, and 
there is a capital sketch of the sacred Singalese relic ‘‘ Buddha’s 
tooth,” whether ‘‘ shed ” or ‘‘ removed ”’ tradition is silent. 
FAUNA OF THE PLONER-SEE. 
WE are glad to welcome the first number of the Forschungsberichte 
aus dey Btologischen Station zu Plén (Berlin: Friedlander), by Otto 
Zacharias, the Director. The number opens, as it should do, with a 
list of the Fauna of the great Pléner-See, the compilation of which 
has brought to light many new forms, all duly described and figured 
in the succeeding pages. These include a Rhizopod, a Heliozoan, a 
Mastigophore, an Infusorian, a Turbellarian, and eight Rotifers. If 
so good a result is achieved in making up a first list, we may expect 
a large addition to our knowledge of fresh-water life from the work 
done at the Biological Station at Plon.
