Description of Ligula Mansoni, a new Human Cestode. By 

 Prof. T. Spencer Cobbold, M.D., F.E.S., F.L.S. 



[Eead December 21, 1882.] 



On the 29th of June, 1882, I received from Dr. Patrick Manson, 

 of Amoy, a small bottle containing numerous flattened shreds bear- 

 ing but slight resemblance to ordinary tapeworms. Tbey were 

 preserved in spirit. The donor, who had the advantage of seeing 

 tbem in the fresh state, recognized their parasitic character, but 

 entertained a doubt as to their cestode nature. I have often 

 received flattened fibrinous clots resembling parasites ; but from 

 the first I conjectured that we had here to deal with immature 

 Lisules. The bottle bore a label with a brief notice to the 

 following effect : — " Tape-like parasites from subperitoneal fascia 

 of Tchai, [who] died, after operation for lympho-elephantoid 

 scrotum, of dysentery, and ulcerated stricture of the oesophagus." 

 The date of this " find " was Sept. 21, 1881 ; but it was not until 

 the 26th of September of the current year that I found leisure 

 to renew my examination of the specimens. In the interval Dr. 

 Manson furnished me vsrith full particulars of the patient. The 

 MS. was forwarded to the Editor of the ' Lancet,' and the case 

 was published on the 14th of October last. In the account of 

 the post mortem there given, Dr. Manson more explicitly states 

 that " a number of parasites, twelve in all, were found lying in 

 the subperitoneal fascia, about the iliac fossse and behind the 

 kidneys. A single parasite was found lying free in the right 

 pleural cavity. Some of these parasites were coiled up in knots, 

 and others lay extended. On being drawn from under the 

 peritoneum, they exhibited languid movements like those of 

 tapeworm." Further on he states that the worms had a "dead 

 white" appearance and "moved distinctly when taken out of 

 the body." 



When I removed the parasites from the bottle, they came
