COLLURIO. 



Rostrum pedesque ut in genere Lanio.

 To the latter group the following Himalayan species belong.

 corpore infra, macula medid alarum, caudce tectricibus, rectricibus 

 duabus lateralibus, caterarumque, quatuor mediis exceptis, basi 

 apiceque albis ; occipite, nuchd, dorsoque imo albescenti-griseis ; 

 dorso medio lateribusque abdominisferrugineis. 

 Rostrum pedesque nigri. Caput superne albo nigroque colore in 

 duas fere partes transversim divisum. Longitude corporis, 8 ; alae 

 a carpo ad remigem 3tiam, 3^--; rostri, -4-; tarsi, ; caudte, 84. 

 Bay-backed Shrike, Lath.? Gen. Hist, vol.11, p. 13. ^.6. 

 This bird appears to be the same as that referred to in Dr. La- 

 tham's work, the description of which is taken from one of the draw- 

 ings of General Hardwicke, to whom the species is inscribed. 

 COLLURIO ERYTHRONOTUS. Coll. strigd froniali per oculos ad 

 medium colli extendente, alis, rectricibusque quatuor mediis ni- 

 gris ; capite supra, nucha, dorso superior i, rectricibusque latera^ 

 libus pailide cinereis ; corpore infra, alarum macula media, remi- 

 gum interiorum apicibus, rectricum lateralium marginibus omni- 

 umque apicibus, albis ; scapularibus , dorso imo, abdominisque la- 

 teribusferrugineis. 



Rostrum pedesque nigri, illius mandibula inferior! ad basin flaves- 

 centi. Striga per oculos nigra, supra graciliter albo marginata. 

 Tectrices alarum inferiores albae. Longitudo corporis, 104^ ; alee a 

 carpo ad apicem remigis 3tia3, 3^; rostri, ^ ; tarsi, \^; caudcz, 4^. 



This bird was observed to bear a great resemblance to the de- 

 scription of the grey-backed Shrike of Dr. Latham, (Gen. Hist. vol. ii. 

 p. 9. sp. 3.) but to differ from it in the colours of the lesser wing- 

 coverts and tail ; the former being all black in the Himalayan spe- 

 cies, and blue-grey, ending in pale rufous in Dr. Latham's, while the 

 tail in the former species had four black middle feathers and the 

 rest cinereous, but in the latter had the two middle ones only black, 

 the rest being white. In a group exhibiting so much similarity in 

 the disposition of the colours as the present, such differences are 

 material as distinguishing species. 



COLLURIO TEPHRONOTUS. Coll. fascia frontali pergracili ad 

 medium colli per oculos latius extendente nigra ; capite, nuchd, 

 scapularibus, dorsoque saturatius cinereis ; collo anteriori pecto-
