Physalia pelagica. Portuguese man-of-war. *N. O. Physophoridae.
G. Bennett was stung by the animal on second and ring fingers. The sensation was as if stung by a nettle, succeeded in a few minutes by violent aching, affecting the finger-joints and spreading up arm, involving elbow-joint. The pain was worse by application of water, worse by motion, and worse when joints became affected. The pain spread to the shoulder-joint and pectoral muscles causing oppression of breathing. After half an hour the symptoms began to abate, leaving numbness of the limb and a vesicle at the spot which was stung.
*Compare: Medusa, Urt-u.
