452 NOVITATES ZOOLOOIOAI: XXVll. 1920. 



described, though at the end of the description, p. 324, stands " $ ad." On the 

 plate the male only is figured, and this agrees with the lettering of the plate, but 

 on p. 323 it is erroneously said that the figure is that of the female ! On p. 324 

 Hartlaub wrote that four specimens were obtained at Langomeri, an adult male 

 and female, and two young birds. We have all these four in the Tring Museum, 

 and the sexes are correctly stated on the labels. The female, which has no black 

 frontal hne, was not described by Hartlaub at all, though he says, " Zunachst 

 erhielten wir nur das ausgefarbbe Weibchen " ! I suppose he meant to say 

 " Mannchen " instead of " Weibchen," and that the " ? ad.," at the end of the 

 description of the male means that it was the author's intention to describe the 

 9 as well, which, however, he did not do.

Lanius excubitorius intercedens Neumann, Joum. f. Orn. 1905. p. 228 (" Hauasch-Gtebiet, siido-

Neumann compared his bird with L. excubitorius jyrinceps, which he thought 

 were L. excubitorius excubitorius, and his intercedens are tjrpical excubitorius. 



520. Lanius antinorii mauritii Neum. = Lanius antinorii mauritii. 

 Lanius antinorii mauritii Neumann, Journ.f. Orn. 1907. p. 595 (Koroli Mountains, West Somaliland). 



Type and unique specimen : ^ ad., Kovoli Mts., 18.iv.l905. Maurice de 

 Rothschild leg. 



It was daring to describe this form from one specimen, and it is desirable to 

 have a series to confirm its validity, but the differences pointed out by Neumann 

 are very obvious, so that the new subspecies appears to be very distinct. 



521. Malaconotus interpositus Hart. = Malaconotus poliocephalus interpositus. 



Malaconotus interpositus Hartert, Bull. B.O. Club, xxix. p. 36 (1911 — North-west of Lake Tangan- 

 yika).

 No. 4,019. 



This form is very closely allied to M. poliocephalus poliocephalus from Sene- 

 gambia to Nigeria, and must be confirmed by further research.
