(Figs. 1-25.) 
Eighteen specimens of a nematode worm (figs. 1-2) have been for- 
warded to this laborator}’^ by Dr. St. Joseph B. Graham, of Savannah, 
Ga. , with the history that they had been taken from a sore on the leg 
of a negress at Darien, Ga. All of the specimens are immature; they 
are not especially well preserved, and on this account they have pre- 
sented considerable difficulty in technique and interpretation. Ac- 
cordingl}^, it has been impossible to give a complete description of the 
species. But as the worm seems to be a new parasite for man, and as 
certain points in the anatomy could be recognized, it seems advisable 
to place the parasite on record, notwithstanding the fact that several 
important points are open to different interpretations and that the 
description is therefore necessarily incomplete. 
Medical history of the case. — For the following medical history 
of the case I am indebted to Dr. P. S. Clark: 
In August, 1896, I was called to see a negress; age, 57; occupation, washerwoman. 
I found her suffering with pain and swelling in and around her left ankle and instep. 
She said she could feel something moving in the swollen places, but there was no 
abrasion on the skin. I gave her a linament with which to rub the affected parts. 
This did not seem to be' of much benefit. She continued to suffer for twelve or 
eighteen months, when suddenly she discovered a w'orm coming out of the most 
swollen place; and worms continued to appear singly at intervals for a month, when 
the opening healed and the pain and swelling subsided, her foot became entirely 
well, and gave no further trouble. She died in 1903 of tuberculosis of the lung. 
I think there were as many as two or three dozen of these worms extruded from this 
opening during the above-mentioned period.

Medicine, at Philadelphia, Pa., March 27, 1906.
