NOTE ON GNATHOSTOMUM SPINIGEEUM. 
By S. N. hitter, G.Beng.V.C., 
Lexturer on Pathology, Royal Veterinary College. 
{From the Raymond Research Laboratory, Calcutta.) 
(With Plate V.) 
Since I published my note on the occurrence of Gnatliostomum 
spinigerum in the stomach of a domestic cat {Journ. Tropical Vet. Sci.) 
two other cases have been observed in this Laboratory. 
(A) While conducting an autopsy on a fox-terrier dog, born and 
bred in this country, two specimens of Gnatliostomum (</ and $ ) were 
found free in the peritoneal' cavity. On opening the stomach, a hard 
tumour with a sinus in the centre was noticed from which a third 
Gnatliostomum protruded into the cavity of the stomach. The sinus 
extended through the tumour (?) to the peritoneal cavity. From the 
peritonal end of the sinus a fourth Gnatliostomum was protruding. 
(B) The carcass of a leopard {Felis pardus) was received Irom 
the Calcutta Zoological Garden for post mortem examination and 
report. The Superintendent informed us that the animal had been 
ailing for two or three days. Two other leopards in the same garden had 
died within two or three daj's with siniiliar symptoms. These animals 
were not however sent for autopsy. 
On opening the stomach two suppurating tumours (Plate V) of the 
size of large walnuts discharging semi-liquid pus were found in the 
mucous membrane. In the contents of the stomach, chiefly mucous, 
were found several free Gnatliostoma, and eighteen specimens were 
found in the tumours. The peritoneal cavity also contained several 
specimens which had no doubt escaped from the stomach through the 
sinuses leading to the peritoneum. Death was due to perforation of the 
stomach wall and gastritis caused by these parasites. 
This species has already been found in the wild cat (F. catus), in the 
puma {F. concolor) and in the tiger {F. tigris).
