From this table it will be seen that of the forty-five genera 
`- noticed, ten are common to the east coast of the Eastern conti- 
nent and the east coast of America only, four additional have the 
same distribution, including Australia and the Pacific isles, three 
are found on both coasts of the Eastern continent an 
eastern coast of America, seven exist only on the shores of 
the Pacific, eleven belong to the Eastern continent and the 
Pacific isles alone, four are found on both shores of America but 
not on the coasts of Europe or the western coast of Africa, three 
seventeen are found on the Pacific coast of America, twenty-five 
on the eastern side, seventeen on the western coast of the Eastern 
gontinent and in the Mediterranean. The cases of the Pacific 
genera which are cemmon to both coasts, e.g., Oregonia, Tel/mes- 
sus, Haplogaster, &c., are in several cases to be explained by the 
fact that they are boreal genera, and analogous cases will at once 
suggest themselves in regard to the fauna of the coasts of the 
North Atlantic. The cases of Liomera luta, which has been 
reported from China, the Pacific islands and C. St. Lucas, Cæno- 
bita rugosa from the Indian ocean, Australia, the Pacific, and of 
which there are specimens in the Museum of the Peabody Acad- 
emy of Science from Panama, and of Platyonichus bipustulatus 
from New Zealand, Japan, India and Chili, are paralleled by simi- 
lar facts in the distribution of Leptopodia siggitaria, Litinia dubia, 
Xantho vermiculatus, &c., which are found on the eastern shores 
of the Atlantic. Another fact to be noticed in comparing the 
fauna of Japan and the eastern seas with that of the Atlantic 
coasts of America is, that certain genera which are peculiar to 
one region are represented in the other by allied forms, for exam- 
ple, Leptopisa, Panopeus and Eucratopsis of the American waters 
are represented on the Asiatic coasts by Ziarinia, Heteropanope 
and Lucratt. 
An examination of Gunther’s Fishes shows a similar identity 
in the genera of the eastern coasts of the two continents, but in 
Edmund Perrier’s article on the Geographical Distribution of the 
Asteridæ no such similarity can be noted. It is my desire to 
Carry out the investigation of this resemblance further, and any 
facts or references bearing on the geographical distribution of 
marine forms will be very acceptable, and due credit will be given 
therefor.— 7. S. Kingsley, Norwich, N. Y.
