2. Troglodytes hypaedon. 



"Troglodytes aedoni," Sclater, P. Z. S. 1859, pp. 363, 372; 

 Sclater et Salv. Ibis, 1859, p. 9. 



Similis T. acdoni ex America boreali, sed colore corporis subtua 

 omnino brunnescenti-rufo ; lateribus corporis saturatioribus, rufis, 

 neque transfasciatis : crisso nigro transvittato. 



Hab. In Mexico meridionali et Guatemala. 



Mus. P. L. S. 



This Wren, which I have heretofore not separated from T. a'idon, 

 is certainly as distinct from that bird as T. parkmanni and other 

 recognized species. It is in fact more nearly allied^to T. furvus of 

 South America than to the northern form ; but differs also from the 

 T, furvus in the deeper colouring of the under surface, the throat 

 and belly of the latter species being medially of a nearly pure white. 



3. Basileuterus uropygialis. 



Olivaceus, capite cinerascente : superciliis, ocuhrum ciliis et cor- 

 pore suhtus pallide cervinis, ventre alhescente : uropygio et 

 caudce dimidio basali pallide fulvis, hujus apice cinerascente 

 olivaeeo : rostra nigro, pedibus pallide carneis. 

 Long, tota 4*5, alse 2'7, caudae I'8. 

 Hab. In Brasilia. 

 Mns. P. L. S. 



I have one specimen of this bird in my collection, received from 

 M. Verreaux and marked " Brazil." It is most nearly allied to B. 

 semicervinus, mihi (P. Z. S. 1860, p. 84), from Ecuador; but the 

 uropygium and body beneath are much more lightly coloured ; and 

 the back is olive and head cinereous, almost as in B. stragulatus, with 

 •which it also nearly agrees in the coloration of the lower surface. 



4. Hylophilus insularis. 



Supra olivaceus, pileo et dorso superiors ochraceo-brunnescetitibus, 

 dorse in/eriore, alls extus et cauda viridescentibus : fronte, ocu- 

 lorum ambitu et corpore subtus pallide ochraceis, tibiis et crisso 

 virescentibus : tectricibus subalaribus pallide citrinis : rostro 

 corneo, subtus pallidiore, pedibus carneis. 

 Long, tota 4'7, alse 2*5, caudse 1*9, tarsi 0*7, rostri a rictu 0'6. 

 Hab. In ins. Tobago. 



I have a single specimen of this Hylophilus, presented to me by 

 Sir William Jardine, by whom it was received from Mr. Kirk, amongst 

 other birds collected in Tobago. It appears to belong to a well- 

 marked though hitherto unnoticed species of this little group, — the 

 bill nearly agreeing with that of H. thoracicus, though stronger and 

 rather more arched, and the feet being likewise rather large and 

 strong. The first primary is rather longer than in any other species 

 of the genus that I am acquainted with, measuring 1-6 (in.) from 

 the base of the wing to its extremity. In //. thoracicus, however, 

 it is perhaps quite as long proportionately, the wing of //. iyisularis 

 being generally larger than that of the former species. In its dull-olive
