Parasite of Flying Fox. — This insect being supplied with such 

 claws, two to each foot, scarcely needs the adventitious aid of 

 either of the quaint zones of processes, or the equally curious 

 appendage at apex of thorax. The animal belongs to the Chirop- 

 tera, of the family Fteropodiz, or Rousettes. The term " Fox " is 

 in allusion to the dog-like form of head. The rough outlines (PI. 

 XVIII., Fig. lo) gives some idea of the head. They are native of 

 the eastern hemisphere, and are the largest of the bats. The 

 Kalong of Java, Pteropiis edulis, measures no less than five feet in 

 extent of wing and nearly two in length. They are nocturnal in 

 their habits, and are vegetable feeders. T. Smith-Rowe, M.D. 



The Rousette. — In addition to Dr. Rowe's remarks, I have 

 added a rough sketch (PI. XVIII., Fig. ii) of the skull of the 

 Rousette. In the East Indies, the chase of Pteropi forms a fre-. 

 quent amusement of the colonists. The flight of these animals is 

 slow and steady, and capable of long continuance. Their ravages 

 among the delicate oriental fruits occasionally cause much annoy- 

 ance to the inhabitants of these islands. Bevan Lewis.
