18C7.] MR. O. SALVIN ON THE BIRDS OF VERAGTJA. 133 



distinguish T. leucauchen from T. ossimilis, Cab., as pointed out by 

 Dr. Baird, L c, and are even paler above than Costa Rican specimens 

 which are referred to the former species by Baird. I am inchned to 

 confine the term assimilis to the Mexican form, as described by Baird, 

 and to refer all these intermediate forms to the Guatemalan T. leu- 

 cauchen. The two more clearly defined species are distributed as 

 follows : — T. assimilis is from ]Mexico only, T. leucauchen from the 

 forests of Northern Vera Paz (Choctum, &c.), and from no other 

 district of Gruatemala. The intermediate forms, viz. those with oli- 

 vaceous backs and partially fulvous under wing-coverts, are found in 

 the highlands of Gruatemala (Duefias abundant, Coban a single spe- 

 cimen, and one from Choctum, the district of the true leucauchen), 

 Costa Rica (Tucurriqui, 3000 feet), and Veragua. I cannot say that 

 this arrangement is satisfactory ; and had the work to be done over 

 again I should prefer to regard all as one variable species, the re- 

 presentative of the South Brazilian T. crotopezus, Vieill., the Cayenne 

 and Para T. phceopyfjus, Cab., and the Autillean T.jamaicensis, Gm. ^ 



I may here notice that the specimens in the collection of the ) } 

 Smithsonian Institution (22,3G0 and 32,G84), marked " Mexico " - ' 

 by jNI. E. Verreaux, possibly came from Guatemala, and originally 

 formed part of a collection which passed through my hands. I have 

 seen specimens of other species with the locality similarly marked, 

 which certainly were in this collection.

Santa Fe, Veragua. 



A single specimen from Santa Fe I believe to be the adult female 

 of this species. I have little doubt that the male is black, and 

 the species closely allied to T. ati-osericens, Lafr. R. Z. 1848, p. 3. 

 In this female the crissum is white, while that of the female of all 

 the allied species is coloured similarly to the abdomen. I append a 

 short diagnosis of this specimen, as Mr. Lawrence's description was 

 evidently taken from an immature bird : — • 



T. saturate brunneus, subfus pallidior: (/ula parce striata : venire 

 imo et crisso albis : tectricibus subalaribus et rcmirjibus ad 

 basin intits citinainomeis : rostro niyro, pedibus obscure cor^j- 

 linis : long, tola 9, alee 49, caudce '6'^ poll. Angl,

The proper systematic position for this curious bird seems to re- 

 main in considerable doubt. Diverse coloration of the sexes is not 

 found in any genus of Troglodijtida-, to which family both Baird and 

 Sclater are inclined to refer it. It may prove that Dr. Hartlaub was 

 not so far wrong after all in rcfcning the female to the Turdidcc. 

 Though I never observed this bird in Guatemala, it ranges thiougli-
