1 (5 26. 4.-, 2 QQ 26. 4. Mombasa. 



Occasionally seen in company with the preceding bird, 

 at times alone or in pairs on the outskirts ot woods, where it 

 frequented the under-growth and bushes. 



Of this King- fisher three forms are recognised: 



1. Halcyon albiventris albiventris Scop. 



Wing 105 — 110 mm. 

 Range: South Africa. 



2. Halcyon albiventris orientalis Ptrs. 



Wing 97—105 mm. 



Range: East Africa, from Witu to Mozambique. 



3. Halcyon albiventris erlangeri Neum. — Bull. Brit. Orn. Club, 

 vol. XXI, 1908, p. 71. 



Wing 92—97 mm. 



Range: Southern Somaliland. 



According to Reich enow (op. cit.) //. a. orientalis is 

 found in Mombasa, from where my three specimens were pro- 

 cured. V. S m e r e n (Journ. E. A. and Ug. N. H. Soc, vol. VI, 

 1918, p. 255) also calls his specimens from Mombasa Halcyon 

 orientalis. Provided the three forms mentioned are good and 

 constant ones, and, judging from the wing measurements, which 

 distinguish them, my specimens should hQ H. a. erlangeri Neum., 

 which Zedlitz (J. f. 0., 1915, p. 28) says is only known from 

 South Somaliland. 



That H. a. orientalis is found in East Africa is certain 

 (compare Lonnberg: Birds coll. B. E. A., 194, p. 74; but, 

 no figures are given for wing-length) and in that case this race 

 and H. a. erlangeri should occur side by side. They are cer- 

 tainly, however, not found nesting together, if so then these two 

 forms may possibly be synonyms. 



These three specimens are all in moult, and only in one of 

 them is the upper back black; in the other two it is dark-brown. 



Irides dark-brown. Bill coral red with dark tip; legs dirty red. 



Wing: cf 98 mm., culmen 45 mm., tarsus 17 mm. 



Wing: 9995 — 96mm., culmen 43— 44mm., tarsus 15 — 16mm.
