[217a]

Genus 46. Species "Isoplexides" not in little book— I think "Echii" = "Isoplexides"

Have reckoned it so.

Genus 180. Species "tristis" not in little book.—

Four of the species which are marked with a x are also marked with an asterisk, and so not counted in the list— this reduces the no. to 35

[217A]

First mark all vars, (corrected as I have done) from big to little Book on left side

~~Then mark with cross those in Mr Wollaston's list~~

Make 3 sets of 4 & upwards, 3, (2 & 1)

Do not count any species marked with one or two asterisks.

Count when list made out how many genera with 1 species

[216b]

Species marked by cross
