Peripatus juliformis
Guilding, 1826

This species became the first velvet worm known to science when Guilding described it in 1826. He thought it was an unusual type of slug, and included it along with his Caribbean mollusks.[3] He named this genus Peripatus (1826). He included an excellent watercolor painting of the specimen, and a mention of the defensive mechanism of sticky liquid squirts. A translation into English from Guilding's description, originally written in Latin, shows how he first classified the specimen in the Class Moluska, and how astonished he was for discovering a new species.[4] The specific epithet juliformis is a Latinisation of juliform, a botanial term meaning catkin-like.
