304 BIRDS OF EGYPT. 



Entire length 30 inches; cuhnen 3"5 ; wing, carpus to 

 tip, 20 ; tarsus 3'1. 



Fig. Gould, B. of Eur. pi. 430. 



334. Larus fuscus, Linn. Lesser Black-backed Gull. 



This Gull ranges up the Nile into Nubia, where I fre- 

 quently saw it in small flocks, generally towards sunset, 

 passing northward in April. On the 24th of that month, 

 near Erment, I shot a specimen out of a small flock, ap- 

 parently the same that I had seen on several consecutive 

 evenings during our retiu-n journey down the river. I have 

 taken my description from this specimen. 



Entire plumage pure white, except the back and wings, 

 Avhich are deep slate-colour, with the primaries black ; a large 

 white spot on the first primary near the tip ; ends of the quills 

 and greater scapulars white ; legs and beak yellow, with the 

 base of the gape and a spot on the lower mandible vermilion ; 

 irides pale yellow ; eyelids vermilion. 



Entire length 23 inches ; culmen 2*3 ; wing, carpus to tip, 

 17; tarsus 2-5. 



Fig. Gould, B. of Em", pi. 431. 



335. Larus LEUCOPHiEUS, Licht. Mediferranenn Hernnc/- 



Gull. 



This Gull is a very abundant resident in Egypt and Nubia. 

 I believe it to have been the species of which I saw flocks oc- 

 casionally in Nubia, apparently migrating northward in April. 

 Von llcughn (Syst. Ueb. p. G9) probably refers to this species
