2. Pristorhamphns versteri meeki, subsp. n. — Hab. Mt. 

 Goliatli (5000 ft.), Central Dutch New Guinea. 



Adult male. Underside darker grey ; about half the 

 second tail-feather white, the white portion measuring BO- 

 SS mm. Tail 75-79 mm. (5 males examined.) 



3. Pristorhamphns versteri o/bescens, subsp. n. — Hob. IVIts. 

 of British New Guinea (Owen Stanley Mts., Upper Aroa, 

 Mam bare and Angabunga Rivers). 



Adult male. Underside lighter, more whitish-grey ; much 

 more than half the second tail-feather white, the white 

 portion measuring 41-4'9 mm. Tail 75-85 mm. (10 males 

 examined.) 



Dr. Ernst Hartert described a new form of African 

 Shrike as follows : — 



Malaconotus interpositus, forma n. 



This form is intermediate between the birds with a 

 chestnut chest-band (M. approximans^ and those with an 

 entirely yellow underside (M. catharoxanthus) , and is thus 

 very similar to the Senegal form, M.poliocephalns. From the 

 latter it differs only in having the brown band of the chest 

 more distinct and confined to the pectoral region, while in 

 the latter the pectoral band is not confined and extends over 

 the sides of the abdomen. 



We have received seven specimens from the districts north- 

 west of Lake Tanganyika, collected by Mr. Rudolf Grauer 

 in tlie years 1908 and 1909. A specimen from Caiala in 

 Eih^, Angola, procured by Dr. W. J. Ansovge, seems also to 

 belong to this form*. Eight skius o£ M. poliocephalus have 

 been compared. 



Obs. I have not employed trinomials for this form, because 

 I am not quite sure whether forms with a uniform pale yellow 

 underside and those with a brown breast occur together. 



* [Examples from the north-west of Lake Tanganyika obtained by 

 Mr. Douglas Carruthera, and from the neighbourhood of Lake Mweru, 

 procured by Mr. Alexander Whyte, do not appear to differ in any way 

 from typical examples of Lmuarius 2)olioce2)halus from West Africa
