COLE : AVES FROM YUCATAN. 131 



Not common; Gaumer (Boucard, Proc. Zool. Soc. Lond., 1883, p. 452) 

 gives it as "very rare" in Yucatan. In the specimen taken by me the 

 under side of the wings is unspotted, a condition which Mr. Nelson thinks 

 is due to immaturity. 



58. *Ceophloeus scapularis (Vigors). 



Delattre's Woodpecker. 



Maya name, ko-lon-te'. Means " master carpenter " ; so called because the 

 largest. 



One specimen : <£, March 23, 1904. 

 Not uncommon. Iris white. 



FORMICARIIDAE. 

 59. * Thamnophilus doliatus mexicanus Allen. 



Mexican Ant-thrush. 



Maya name, ta-ta-tsel. This name appears to be applied only to the female ; 

 the same name is given to Sittasomus and Dendrornis. 

 Three specimens : 



a. $, March 11, 1904. 



b. 9, March 12, 1904. 



c. sex % Yucatan (Xbac ?), 1901, G. F. Gaumer. 



Like Chapman I found this bird not common. Iris of male yellowish', not 

 noted in the female. 



DENDROCOLAPTIDAE. 



60. Synallaxis erythrothorax Sclater. 



One specimen : Chichen-Itza, 189 -, E. H. Thompson. 



Gaumer (Boucard, Proc. Zool. Soc. Lond., 1883, p. 449) gives the Maya 

 name of this bird as ' ' Tzapatan ' ' (oa-pa-tan) . 



61. * Dendrocincla anabatina typhla Oberholser 

 Proc. Acad. Nat. Sci. Phila., 1904, p. 452. 

 Wood Hewer. 



One specimen : Chichen-Itza, 189-, E. H. Thompson. 



The marked paleness of this specimen was noticed before it was compared 

 with Oberholser's description of the subspecies. It would appear to be a 

 characteristic condition of the Yucatan birds. 



62. * Dendrocincla homochroa (Sclater). Wood Hewer. 



63. Sittasomus sylvoides Lafresnaye. 



Maya name, ta-ta-tsel. Refers to its working about wood; the ta-ta is in 

 imitation of the tapping sound made with the bill.
