Struthionidae. 



Struthio massaicus Neum. — Rchw. I. p. 10. 

 1 (5 ad. 20. 9.; 1 Q ad. 20. 9., Thika. 



These two specimens were shot by Director L o v e n while 

 on a shooting trip in the Thika districts. Being unable to make 

 an examination on the spot I give Mr. Lovcn's brief description: 

 "The male: head, bill and legs milk-coloured with a bluish tint; 

 metatarsus and toes milk-coloured, somewhat pinkish in front. 

 The female: head and neck grey with a greenish hue, bill dark 

 grey, dark-coloured, darkest at the edges; legs and toes light 

 grey, scales brownish grey." 



This Ostrich was common in the regions around Nairobi 

 and further southwards and I frequently saw them running about 

 the plains in large flocks. They were plentiful in the Game 

 Reservations. 



L V 6 u also brought home a number of the eggs of this 

 species, which he found on the same day as these individuals 

 were shot. 



Larldae. 



Larus cirrocephalus Vieill. — Rchw. I. p. 44. 



Ongwaee . . . ki-kaviroudo. — Kanyange . . . ki-kamba. 

 1 (5 ad. 21. 8., Kendu. 



This species was very common at Kendu, on the Gulf of 

 Kavirondo, and occurred in large flocks on the shore. This Gull 

 was also found in considerable numbers at Lake Naiwasha. The 

 specimen is in summer dress.

Irides not uniform pale yellow (Reichenow) but had 

 nearest the pupil a rather wide pale-yellow ring surrounded by 

 another of chocolate-brown colour; bill dark red; legs coral red.
