APHANIPTERA. 31 
the pro-thorax. Mr. Haliday first discovered the antennz of this 
species. They are two-jointed, short and flat, the first joint having 
a bristle near its internal apex, and the other crowned with spines. 
This species is common on the dog and fox, and most other 
members of the Canida. 
Pulex galling, Bouché. ° 
Deep black above, testaceous below. Differs from zvritans in 
being smaller, more compact, and in the length of the antennz, 
which are lanceolate, the last joint being thin. Maxillary palpi 
slender and filiform. Femora bare ; tibize and tarsi spinose. 
There is a curious comb-like fringe to the pro-thorax. 
This species is common on the domestic fowl, and especially in 
the nests. Hundreds may be got by putting the hand in the nest. 
It is also found on other birds, as the thrush, robin, and in the nests 
of the blackbird. Mr. Dale believes a species described by West- 
wood from Ceylon as Sarcopsyllus galiinaceus, to be identical with 
the one just described.* 
The larve of Gad//ine are darker than those of the domestic flea, 
and are found in birds’ nests. 
P. galliné is also recorded from the nests of the house-martin and 
from those of the sand-martin, in the cracks in the clay. ‘Those 
from the nest of the sand-martin were darker than those from the 
house-martin, and they may be a distinct species.” F 
We have found P. Airundints in the nests of the house-martin, but 
never Gadling, although repeated searches have been made. PP. 
hirundinis does not seem to be given by Verrall; it nevertheless 
seems to be a perfectly distinct species. May not the Ga/dine, 
recorded above, be the same? 
Pulex hirundinis, Sam, Curtis, and Walker. 
Differs from Gadline by being testaceous, and by not being so 
elongated and having shorter antennz. There is also a black band 
on the hinder part of the thorax, | 
Abdomen and legs setose. Antennz four-jointed ; the basal joint, 
having three or four long bristles attached to it, can be entirely 
withdrawn into the pits. Eyes small and lateral. Maxillary palpi 
slender, the top segments having a few hairs. Labial palpi setose at 
the tips. Joints of tarsus gradually decreasing from the first to 
fourth, the fifth being larger than the fourth, and with more bristles 
on each side. 
This species may include P. columbe and Fringilla of Walker,
