Specimens from Vuc;it;in ww "mterinodiate between Injpaedou :ind

 species from Salvador or from northern Honduras have V)een examined, 

 so tliat I am unable to say whethei' it is Jn/paedon or intermedins that 

 oeturs in those localities. 



TROGLODYTES MUSCULUS INTERMEDIUS (Cabanis). 

 Troglodytes intentmliui^ (.'akanis, Joiirii. of Orn., I860, \>. 407. 



Ti/pe locality. — San Jose, Costa Rica. 



Geogr'aphlcal distrihntion. — Costa Rica to southern Honduras. 



This is a dark form. ap})roaching true mtisculus^ from which it dif- 

 fers in havino- w shortei' tail, more heavily barred crissum. and barred 

 flanks. 



TROGLODYTES MUSCULUS INQUIETUS (Baird). 



Troglodytes inquietus Bairv, Rev. Ainer. Birds, I, 1864, p. 143 (Lawrence manu- 

 script). 



Type locality. — Panama Railroad, Isthmus of Panama. Colombia. 



Geographical dht I'lhut ion. — State of Panama, (x)lombia. 



Though seldom recognized as a distinct form, this race has b en 

 placed sometimes under inter niedius., sometimes under striatulu:. a 

 circumstance which of itself lays strong emphasis upon its inter- 

 mediate character; yet almost without exception Troglodytes in. inter- 

 medium and T. m. striatulus have been treated as distinct species. 

 While uiidoubtedl}^ close to the latter, ditfiu-ing chiefly in the more 

 rufescent and usually' somewhat darker upper surface, inquietus., under 

 the circumstances, is pro])ably l)est kept separate. From intermedius 

 it may be distinguished by its more grayish upper paits, more whitish 

 median and more grayish lateral lower surface, more plainly barred 

 flanks and lower back. Though superticially resembling the more 

 grayish specimens of clarus^ it has a nuich more heavily l)arred cris- 

 sum, l)arred and more rufescent flanks, with th(^ dark bars of the tail 

 usually more broken. 



TROGLODYTES MUSCULUS STRIATULUS (Lafresnaye). 



Thriothorus strlatuln.s LwuEssw a, Rev. Zuol., 184."), ]>. ."JoS. 

 Troglodytes columb.T Sto^e, Proc. Acad. Nat. Sci. Phila., 189W, p. 308. 

 Type locality. — Bogota, Colom))ia. 



Geograpliical distrihxtion. — Coloml)ia. excepting the Santa Ahirta 

 region and the State of Panama. 



This form is easily distinguishable from TroglodytiK m. intermedia^ 

 by its much less rufesc(Mit uppei' parts and usually more whitish under 

 surface. Examination of a good series of st/-iatt/l'is- makes evident the 

 existence of a wide range of variation that seems to ])e (juite certainly 

 but individual. The color varies fi'om warm yellowish brown or
