(6) D. rufigula paraensis Lorenz-Liburnan. 
Dendrexetastes paraensis Lorenz-Liburnau, Verhandl. Zool. Bot, Gesellsch. Wien xlv. p. 363 (1895.— 
Para) ; idem, Ann. Hofmus, Wien xi. 1896, pp. 1-4. pl. 1. 
Hab. N.E. Brazil: Marco da Legoa near Parad (Princess Therese of Bavaria). 
Characters. Differs from D. r. rufigula by its stronger, stouter bill, slightly 
darker back, duller, more earthy brown under parts, and especially by having a row 
of distinct, though narrow, white streaks, laterally bordered with black, running 
along the upper margin of the ear-coverts, from the sides of the neck to above 
the eye. 
1. Immature, Marco da Legoa, Para, Zype. Wing 104; tail 100; bill 32 mm. 
Obs. I am under great obligation to H.R.H. the Princess Therese of Bavaria 
for the loan of the typical specimen. 
(c) D. rufigula subsp. 
Hab. North Brazil : Calama, right bank of the Rio Madeira. 
See above. More material is required to establish the status of this form ; 
it would not be scientific to base a new name on a single immature specimen. 
(d) D. rufigula devillei (Lafr.). 
Hab. Eastern Pera: Sarayacu (Castelnan & Deville), Iquitos (Whitely), 
Samiria (Hauxwell). Western Brazil: Bom Lugar, Rio Parts (Snethlage) ; 
Humaytha, Rio Madeira (Hoffmanns). : 
Characters. Differs from (a) and (6) by lacking the white longitudinal streaks 
on the nape and sides of the neck. Moreover, the throat is uniform ochreons, 
without any trace of white stripes ; the foreneck only shows a number of narrow buff 
shaft-lines ; the ground-colour of breast and abdomen is much more tinged with 
ochraceous. The bill, too, is paler, the upper mandible being light yellowish grey, 
like the lower one.
