Mr. Darwin’s collection contains individuals of five species belonging
to this family, besides the drawing of a sixth; but the specimens
brought home are dry, and badly preserved. Two appear to have been
previously noticed; but it is difficult to pronounce upon the other
three with certainty, neither do they admit of being very accurately
described. These last, therefore, I shall not venture to name, but
merely point out a few of their principal characters, adding the
localities whence they were obtained.
The species, of which there is a drawing, I conceive to be certainly
new; and as its characters are very distinguishable, I shall name it in
honour of the gentleman, one of the officers of the Beagle, by whom the
drawing was made.
