BURNETT'S GONIOCOTES. 
(Goniocotes burnettii Packard.) 
A species described by Dr. A. S. Packard (Am. Nat. vol. iv, p. 94) 
is apparently much less common than some of the other species com- 
mon to the sadly infested barnyard fowl. According to Dr. Packard's 
description it differs from the G. hologaster of Europe, 
which lives on the same bird, in the short second joint 
of the antennae, which are also stouter, and in the long 
head, the clypeus being much longer and more acutely 
rounded, while the head is less hollowed out at the in- 
sertion of the antennae. The abdomen is oval and one- 
half as wide as long, with transverse, broad, irregular 
bauds along the edges of the segments. The mandibles

cotes burnettii Pack. 
are short and straight, two-toothed. The body is 
(After Packard.) slightly yellowish and variously streaked and banded 
with pitchy black. 
GONIOCOTES OF THE PHEASANT. 
(Goniocotes chrysocephalus Giebel.) 
This parasite of the pheasant was first described by Giebel iu 1866 
under the name of Goniocotes colchici which he afterward changed to 
the above. It is said to resemble the hologaster which affects the do- 
mestic fowl. 
THE CHICKEN GONIODES.' 
(Goniodes dissimilis Nitzsch.) 
Although this species has been known for a considerable time, 
not to have been abundant enough to receive frequent notice. 
Denny says: "I suspect this species of being 
of rare occurrence, as the only specimen which 
I have examined was communicated by Mr. 
Thompson from Belfast, and that being a female, 
1 am precluded from describing the character- 
istics of the male." 
It is a large species, 2 to 2£ millimetres 
iu length, and Denny describes it as tawny 
iu color, smooth, shining, and pubescent, with 
large subquadrate head, a short transverse 
prothorax, and a large abdomen with the side 
markings confluent, and the sutures with deep 
chestnut bands. It has not as yet been recorded 
for this country that Ave are aware of, though 
in all probability it occurs here as well as in < AfterI)enn y ■> 
Europe.
