of the San Juan River is also said by Hellmayr (P. Z. S., 1911, p. 1176) to 
have the back “rather more brownish than a Bogota skin.” 
Unfortunately I have seen no specimens of C. c. brunneinucha, described 
by Berlepsch and Stolzman from Central Peru (P. Z. S., 1896, p. 385). 
While chocoensis appears to be nearer this race than to castaneiceps, the 
pileum and nape in the Peruvian bird are said to be of the same color as the 
back, whereas in chocoensis as well as castaneiceps they are essentially the 
same color as the forehead. Doubtless a comparison of specimens would 
reveal other differences. Meanwhile the two races can apparently be 
distinguished by size alone, as the appended measurements of males indicate.

Microbates cinereiventris magdalene subsp. nov. 
Char. subsp.— Differmg from both M. c. cinereiventris and M. c. torquatus in 
having the tail tipped with whitish, the color both above and below paler, the tail, 
and particularly bill, longer; differs from cinereiventris, its nearest geographic ally, 
and agrees with torquatus, in having no postocular spot. Wing, 55; tail, 30; tarsus, 
24; culmen, 21.5 mm.. | 
Type.— No. 1383479, Am. Mus. Nat. Hist., o ad., Malena (alt. 1000 ft.), near 
Puerto Berrio, Antioquia, Col., March 10, 1915; Miller and Boyle. 
Remarks.— The discovery of this interesting race extends the species 
eastward to the Magdalena Valley. Although resembling M. c. torquatus 
of Panama and Costa Rica in the absence of a postocular mark, it is evidently 
wholly cut off from that race by cinereiventris to which form four specimens 
secured by Anthony and Ball in eastern Panama (Tacarcuna) are referable. 
This proposed race is based on only the type, which has been compared 
with the type of M. c. torquatus and sixteen specimens of M. c. cinereiventris, 
including four from Barbacoas, which may be considered topotypical. 
Xiphorhynchus lachrymosus alarum subsp. nov. 
Char. subsp.— Similar to X. 1. lachrymosus (Lawr.) but buffy, guttate spots on | 
the back smaller and narrowly margined with black and more widely with Dresden- 
brown, rather than broadly margined with black; spots below averaging smaller; 
lesser wing-coverts with much less black, the outer greater coverts margined exter- 
nally with brownish above instead of Bikok.
