NOVITATES ZOOLOaiCAE XXIV. 1917. 499 



Habitat : Andes of Merida (Escorial, 3,000 ni. ; Walle, 2,l(i5 m.). 



Type : J ad. Escorial, 15. v. 1903, Salomon Briceiio Gabaldon & Sons coll. 



We have a male, apparently not quite adult, collected by 0. T. Baron at 

 Guayabamba, 5,500 ft., on September 23, 1894. This bird closely resembles 

 topo-tyfjical Bogota birds, but is stUl a little lighter on the upperside, and the 

 bill is shorter than in Colombian and Merida specimens. 



Sclateria naevia trinitatis, subsp. nov. 



o ad. Upper- and underside much jDaler than in 8. n. naevia, more slaty grey 

 than dark slate-colour ; there is generally more white on the underside, especially 

 on the throat. $ ad. Also much paler on the upper- and underside, the white 

 centres to the feathers of the breast and abdomen mostly larger. Size the same 

 as that of S. n. naevia. 



Hab. : Trinidad. 



Type: S Caparo, Trinidad, 10. iv. 1902. E. Andre coll. 



We have received 4 cjr? and 2 $5 from Caparo, Andre coll., and a o and a $ 

 from Savana Grande, Trinidad, 18. ii. 1897, Dr. Percy Rendall coll. 



Of S. naevia naevia wc have before us three males and two females from 

 Cayenne, three males and one female from Surinam, and a female, collected by 

 F. Schwanda at Miritiba, State of Maranhao, Brazil, 18. ii. 1908. This seems 

 to be quite a new locality for this species, though Dr. Snethlage records it from 

 Para, Ilha das Onfas, St. Antonio do Prata, and Rio Acara. 



The subspecies of Pseudocolaptes boissonneautii. 



Hellmayr and SeOern, Archiv /. Naturg. Ixxviii. p. 99 (1912) gave a short 

 review of the subspecies of P. boissonneautii, but the case is not so simple, and 

 much more complicated, than they thought. 



We have nothing to say about P. boissonneauiii slriaticeps from the coast- 

 mountains in Northern Venezuela, which is quite distinguishable, but we cannot 

 unite the birds from Merida, of which we have 12 adult and 2 juvenile specimens, 

 with the typical boissonneautii from Colombia. They differ fi'om the latter not 

 only in the throat being distinctly yellowish as in striaticeps, but there are also 

 other differences. The chest has a less scaly appearance, as the feathers have 

 no blackish edges and are more yellowish ; the abdomen is generally, but not 

 always distinctly lighter, but the tail is always lighter from above and below. 

 Ill our opinion the Merida form is therefore undoubtedly nearer related to 

 striaticeps than to P. b. boissonneautii. In fact it differs from striaticeps only 

 in the more blackish crown of the head, the less scaly chest, and the lighter 

 rump and tail, and under wing-coverts and lining of the wing. The length of 

 the bill is variable, differing accordmg to sex and age, and also individually. 

 'We call this form 



Pseudocolaptes boisonneautii meridae, subsp. nov. 



Type : " J " (but evidently $, having the bill very Long), Vale of Merida, 

 IG. ii. 1888, Salomon BrLcono Gabaldon coll. (Tring Museum). 



OiJy one form has been recognised in Peru, but this cannot be quite correct. 

 P. boissonneautii flavescens was described from Marajmioc (cotype in Tring) in 

 Central Peril, whidh is the ttorra typHca. thotigb a skin from CuferVo in NorthLTii
