432 Mr. R. B. Sharpe on Dr. von Heuglin^s 



to be right in considering S. pallida, Riipp., to be the young of /S?. 

 monacha. S. modesta is a new species described for the first time ; 

 but the name cannot stand, since it was conferred some months 

 previously on another bird by Mr. Tristram (Ibis, 1869, p. 206), 

 unless Dr. von Heuglin can show that he had complied with the 

 recognized rules in his application of it — rules which require rather 

 more publicity than that afforded by its display in a museum, 

 even though that museum be at Leyden. Again, his S. scoto- 

 cerca cannot be recognized, that species being RuticiUa fusci- 

 caudatn, Blanford (Ann. & Mag. N. H. 1st Nov. 1869, p. 329). 



The Turdidce of Dr. von Heuglin's work call for little remark ; 

 but I rather doubt if a comparison of the true Ixus nigricans, 

 from South Africa, with Abyssinian specimens, would confirm 

 the identity of the two species. 



As regards the twelfth and thirteenth parts, which have just 

 been received, I must notice that the care bestowed by the author 

 in the revision of the former parts falls rather short here ; and 

 there are several clerical errors, which seem to point to more 

 hurried composition, and somewhat mar the appearance of the 

 printing. Having drawn the attention of the author to this 

 omission, which the cai*e exhibited in the former portion of the 

 work renders the more conspicuous, I may proceed to observe 

 that in the family Amjjelidce are included Campephaga and Ce- 

 blepyris. It would be a great boon if some one would define the 

 limits of this family, which seems in the eyes of several ornitho- 

 logists to be a refuge for the destitute, whei'ein may be lodged 

 any kind of aberrant form whose place cannot be readily as- 

 signed. Thus we find in the * Vogel Ost-Afrikas ' Bradyornis 

 placed here by Drs. Finsch and Hartlaub. Now BradT/ornis 

 appears to me to be more of an aberrant Chat than anything 

 else, having certain allies in those peculiar African species which 

 cluster in the neighbourhood of the true SaxicolincB, and form a 

 tangled knot around that subfamily. Campephaga and Ceblepyris 

 I also regard as aberrant Shrikes ; but I wish to give no positive 

 opinion on this subject, as it requires more careful study and 

 much further consideration than my present oppoi'tunities have 

 permitted. To Ceblepyris pectoralis must be added our new Cam- 

 pephaga andersso7ii (P. Z. S. 1870, p. 69, pi. 4) from Damaraland,
