lu July 1863 a number of shells and zoophytes were 
brought in by my son, Mr Strethill Harry Wright, which 
were dredged in the neighbourhood of Inchkeith. They 
were placed in vessels of sea-water, and in a few days a 
number of the rhizopods, to which I have given the name 
of Boderia, appeared on the sides of the glass. The animal 
(fig. 1) consists of a simple mass of deep brown, sometimes 
orange, sarcode, enclosed in a very delicate membranous 
envelope, from openings in which it protrudes long pseu- 
dopodial branches, generally three or four in number, but 
sometimes more numerous, especially in the larger specimens. 
Its shape is variable, sometimes presenting the appearance 
of a conical mass with pseudopodia spreading over the glass 
to which its base adheres ; at other times, that of an ex- 
' tended plate with many angles, from each of which protrudes 
a pseudopodial branch. In the majority of individuals a 
single large nucleus (fig. 1, a) only appears, spherical and 
transparent, but in others three or four such bodies occur 
This animal was first named Turneria, after W. Turner, M.B., who kindly 
assisted me In the examination of it ; but as " Turneria" was found to be 
preoccupied, " Boderia," one of the ancient names of the Firth of Forth, was 
adopted.
