SOME PARASITES FROM CEYLON.

GIGANTORHYNCHUS GIGAS (Goeze). 



Five or six specimens of this parasite were taken from the 

 stomach of a Sus cristatus killed at Batulu-oya. Judging from 

 their size they were all males. The position of the parasite in the 

 host is worth remarking. These animals usually come to rest in 

 the small intestine, notably in the duodenum, but the specimens 

 in question were found in the stomach. The secondary host of 

 G. gigas is some species of beetle, most usually in Europe the 

 cockchafer, Melolontlia vulgaris, but Cetonia aurata is also incri- 

 minated. In North America the beetle Lachnosterna arcuata 

 and allied species harbour the younger stages of the Gigan-

A single specimen was taken from the left lung of a Python 

 molurus, which also harboured the immature nematode, Ascaris 

 rubicunda (?) Schn. The duodenum of the same snake was 

 packed with the cestode, Bothridium py thorn's, Blainv.
