THE extremely rare occurrence of this parasite and the
absence of any drawing of it, or of the lesions it causes, are
sufficient reasons for this short note.

Neumann says: "There are five observations on record
of verminous nodules of the trachea and bronchi of the
dog, caused by the Nematodes that Blumberg and Rabe
doubtfully place in the genus Filaria. Of these five obser-
vations, one is due to Renault, two to Blumberg and the
other two to Rabe. Body filiform, mouth surrounded by
two or three prominences or concentric lips of variable
height behind which are three unequal papillæ; pharynx
dilated Male 5 mm. long with the posterior extremity
rounded; two curved, unequal spicules. Female 9 mm. to
15 mm. long; vulva situated immediately in front of the anus.
"Ovoviviparous.—These worms, imbedded as they are
in the substance of the nodules, are very difficult to extract,
and their study is still incomplete."

In April of this year I found this parasite in a fox-hound
belonging to the Lahore Hunt.

The dog was whelped in Lahore at the end of January
1908. It was kept at Dalhousie all the summer of that year
and died in April 1909 in Lahore from contagious gastro-
enteritis.

On opening the trachea the appearance shown in the
drawing was found.

Altogether there were about 30 nodules 3.5 mm. long
and 2.3 mm. wide, through the surfaces of which the worms
protruded their head-ends, about half the worm being inside
the tumour and half in the lumen of the trachea.
