Osyluth

An osyluth, sometimes known as a bone devil, is a tall, emaciated fiend with dried skin stretched so tight as to outline and emphasize every bone in its body. It has a skull-like head and a bony scorpion-like tail and exudes a stench of decay. An osyluth stands about 2.74m (9ft) tall and weighs roughly 227kg (500lbs). Osyluths often serve as the informers and police of the Nine Hells, monitoring and reporting on the activities of other devils.

Osyluths, along with hamatulas, make up the bulk of the Servants of Mammon, Mammon's personal army.
