proves to be a Lipeurus, or at least it agrees with L. heterographus in 
most particulars. Occurs also on ducks. (See L. heterographus, also 
technical notes.) 
THE CHICKEN GONIODES. 
: (Goniodes diassimilis Nitzsch.) 
Although this species has been known for a considerable time, it 
seems 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 com. 
municated by Mr. Thompson from Belfast, and that 
being a female I am precluded from describing the char- 
acteristics of the male. 
It is a large species, 2 to 25 mm. in length, 
and Denny describes it as tawny in color, 
smooth, shining, and pubescent, with large 
subquadrate head, a short trausverse pro- 
thorax, 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 we are aware 
of, though in all probability it occurs here as well as in Europe.

GUINEA FowL GONIODES. 
(Goniodes numidianus Denny.) 
We have only the record given by Denny (Monog. Anop. Brit., p. 
163, Pl. XIII, fig. 7) as authority for this species. His diagnosis of 
the species is as follows: “Pale straw-yellow, shining and smooth, 
margined with. black; head suborbicular; abdomen acuminate, with 
pitchy brown, interrupted transverse bands.” He states that “the 
_ only specimens of this species I have seen are two males, which I took 
from off a pintado (Numida meleagris).”. We have not had the oppor- 
tunity to search for this species and can not say whether any effort has 
been made in this country to obtain parasites from the guinea fowl. 
It is most likely that a careful examination of a number of the fowls 
would furnish examples of this species and possibly still others not yet 
recognized. 
THE PIGEON GONIODES. 
(Goniodes damicornis Nitzsch. ) 
According to Giebel, this species was first described by Nitzsch, and 
_ his reference is “ Zeitschrift f. ges. Naturwiss., 1866, XVII, 119.” It is
