498 NOVITATES ZOOLOGICAE XXIV. 1917. 



The following material is in the Tring Museum, in addition to which, that of 

 the British Museum has been examined : 



T. (J. doliatus : 11 o'cJ, 9 ?? ad. 

 T. d. fratercidus : 35 <J<J, 26 ?? ad. 

 T. d. tohagensis : 8 o"o, 7 ?? ad. 

 T. d. cat us : 12 ^Jo^ 14 ?? ad. 

 T. d. submdiatus : 7 <?<?, 6 ?? ad. 

 T. d. difpcilis : 8 oo^ 6 92 ad. 



r. nigrescens occurs together with T. d. doliatus, and judging from the 

 description {Field 3Iiis. of Nat. Hist. vol. i. No. 7, p. 290, and No. 10, p. 337) 

 a race of it has been described from Zulia. Venezuela. 



Thaninophilus bernardi baroni, subsp. nov. 



A series of seven skins in the Tring and British Museums collected by 0. T. 

 Baron in North-west Peru (TrujiUo and Yonan River) differ from typical T. b. 

 bernardi from GuyaquU, Puna I., and Tumbez (Brit. Mus.) in both sexes being 

 much darker above, especially the females, which are rich dark chestnut mstead 

 of brown or brownish chestnut ; ear-coverts and sides of the head in the female 

 more blackish ; bill generally longer. Wings also longer. W'ings in the males 

 86-88, in the females 80 mm., as against typical males with wings measuring 

 Guayaquil 80, Puna I. 81, females Guayaquil 75, Puna I. 76. Birds from Puna 

 Island are slightly more greyish above and therefore slightly paler than birds 

 from Guayaquil. 



Type: o ad., Yonan River, 3,000 ft., north-east of Trujillo, 15. vi. 1894. 

 0. T. Baron coU. 



Note on Myrmeciza longipes griseipectus. 



There is a curious variation in the males of this subspecies, and there are 

 probably several forms of it. It was described, under the name of Myrmeciza 

 swainsotti griseipectus from the Orinoco, the type being from Caicara. The four 

 Caicara specimens have all a very light rufous upperside and small black spots 

 on the wings. Seven Guiana specimens have the same light rufous colour of the 

 upperside and no black spots on the wings or only indications of the latter. The 

 specimen from Munduapo (one) and four from the Caura River are darker chest- 

 nut and have all large, strongly marked black spots on the wings. The two 

 o birds from Obidos, on the Amazons River, are quite as dark as those from the 

 Caura and Munduapo, and equally heavily spotted. The females of all the sub- 

 species of longipes have spotted wings. 



Therefore there seem to be three different subspecies instead of one, because 

 in M. longipes longipes (8) and pananiensis the males (6) have always unspotted 

 wings and the variation in the shade of rufous on the upperside is small. 



Further material should be examined, to clear these questions. 



Synallaxis luiirufa meridana, subsp. nov. 



Differs from 8. unirufa unirufa by its darker, more rufous colour throughout, 

 and especiall}' the dark-chestnut tail, which is much darker than the rest of 

 the upperside, while in S. unirufa unirufu the tail is almost uniform with the 

 head and back. Wings 59-62, tail 90 mm.
