196 INSECTS AFFECTING DOMESTIC ANIMALS. 
a rather large species, a little more than 2 mm. in length and of a 
bright-brown color. The head is very much rounded in front and 
strongly angular behind. It occurs only on 
pigeons, but upon these appears to be rather 
common, though not yet met with in our own 
collecting. 
THE LITTLE PIGEON GONIODES. 
(Goniodes minor Piaget.) 
Piaget (Les Pédiculines, p. 256) has described 
as a distinct species, under the above name, a 
form quite similar to the preceding but smaller 
and presenting some differences of the antennz 
and form of the head. According to this

quata. It has not to our knowledge been re- 
corded in this country as yet, but is likely to be found along with the 
other forms. 
LOUSE OF TURKEY. 
(Goniodes stylifer Nitzsch.) 
Nitzsch describes this species in Germar’s Magazine (III, 294), and it 
has been frequently mentioned since that time. It was also described 
by Schrank under the name of Pediculus meleagris (Faun. Ins. Aust., 
504). It is alarge species, 3 mm. or more in length, and quite readily

distinguished from other common species by the hind angles of the 
head, which are extended backward into long styles, from the ends of 
which extend strong bristles. The thorax is angular, with a black mar- 
gin, and the abdomen is pale, with transverse bands of dark color. 
The species probably has a distribution equal to that of the turkey 
itself, and with the other species common to this fowl render it pretty 
thoroughly infested.
