Features additional notes in Gwillim's hand regarding crocodile's size and where it was found: on the drawing in pencil, a small number "51," "10 feet [unclear]," and "A [unclear] aligator taken from the ditch at Vellore." Other pencil inscriptions on the mat read, "Crocodilus palustris" (at side) and "Crocodilus palustris / A aligator taken from the ditch at _ ?" (at bottom). The "10 feet" on the drawing has been re-written underneath.
