circumstances that have placed me under obligations to several 
persons and institutions. These I would here acknowledge, 
and that most gratefully: first of all to Mr. Alexander 
Agassiz, through whose generosity it was that I was enabled 
to occupy a table at the Zodlogical Station at Naples for 
some months during the fall and winter of 1894; next, to 
Prof. Dohrn and all those associated with him in making 
the Naples Station the realized ideal of what such an institu- 
tion should be; and last, but by no means least, to Prof. 
F. E. Schulze, who so kindly and generously placed the 
excellent facilities of the Zodlogical Institution of the Uni- 
versity of Berlin at my service for some months.

My specimens were all collected by myself at Santa Barbara, 
California, during a brief visit there in the last days of Decem- 
ber, 1892. 
They were all found upon the beach where they had been 
thrown by the waves; I saw no colonies in their original posi- 
tions. As they were found in abundance and in a perfectly 
fresh condition, I conclude the species must be plentiful at 
this point, and that it lives on the sea bottom not far from 
the shore. This latter supposition is likewise supported by 
the fact that most of the colonies are attached either to 
shore-inhabiting seaweeds, or to Szyela rubra, an Ascidian very 
common at Santa Barbara on the piles of the wharf, and on the 
rocks in shallow water. It is almost certain that the dredge, 
when brought into use here, will bring it up from its natural 
abode in quantities. On account of its obvious abundance at 
this point, I have been somewhat surprised at not finding it 
elsewhere on our coast; but there is little doubt that further 
work with dredge and tackle will bring it to light at other 
places. 
As the only killing reagents with which I was provided on 
my visit to Santa Barbara were picro-sulphuric mixture and
