This original heading, and the absence of the erroneous synonym from
the MS., confirm the received opinion of the identity of the Museum

M. HIPPOCASTANUM. _M._ ecaudatus edentulus, fauce edentula integra,
spinis serie triplici.
Gualtieri's erroneously cited figure was not indicated in the
manuscript. No specific name had been originally attached to the
description.
M. MELONGENA. _M._ ecaudatus edentulus fauce patula lævi, spinis serie
duplici.
"Bonan. 3. f. 186" had been added to the synonymy by our author. The
details were less copious than in the published edition, "apice solo
acuminatus" being the meagre substitute for the entire description
from "Spira" to the end.
