-specimen) 6.50, wing 2.80, tail 3.10, exposed culmen .75, bill from 

 nostril .55, tarsus 90. 



The measurements of five adults of C. brevirostris are as follows : 

 length (mounted specimens) about 7.00-7.30, wing 3.20-3.45, 

 tail 3.40-3.60, exposed culmen .65-. 85, bill from nostril .55-.60, 

 tarsus .95-1.00. 



10. Campy lorhynchus minor (MS. only?). Type, No. 2620, 

 locality unknown. 



This is a young bird in first plumage, and belongs to the same 

 group as G. nuclialis Cab. and C.pardus Scl. It may be referable 

 to one of these two species, but this I am unable to determine 

 from the material at hand. 



11. Thryothorus rufalbus (Rev. Zool. 1845, 337). Type, No. 

 2647, "Mexico." 



This specimen is clearly a t3 T pical example of the northern (Gua- 

 temalan) race which Professor Baird named Thryophilus rufalbus, 

 var. poliopleura (cf. Review, pp. 128, 129), which name must there- 

 fore sink into a pure synonym of T. rufalbus. There is in the La- 

 fresnaye collection another specimen marked as type of T. rufalbus 

 (No. 2649, "Columbia") ; but since only "Mexico" is mentioned 

 as the habitat in the original description, which furthermore agrees 

 exactly in all essential points with the so-called Mexican specimen, 

 there can be no doubt as to which is really the type. Unless the 

 name Troglodytes cumanensis Cab. (J. f. O., 1860, 408, ex Licht., 

 MS.) is found to be applicable to the southern form, I do not know of 

 any available name for that subspecies. According to Cabanis 

 (I. c), T. cumanensis, which is from Cartagena, differs in several 

 respects from the ordinary bird from the interior of Columbia (Bo- 

 gota, etc.) ; and if this proves to be really the case, the name in 

 question should be restricted to the coast form. Pending the de- 

 cision of this question, it may be well to provide a provisional 

 name for the bird which Professor Baird considered to be the true 

 T. rufalbus, the range of which extends from Nicaragua to the 

 highlands of Columbia, and I therefore propose for it that of Thryo- 

 philus rufalbus castanonotus . 



12. Thryothorus maculipectus (Rev. Zool., 1845,338). Type, 

 No. 2657, " Mexico." 



This specimen is identical in coloration with Mexican examples 

 in the National Museum collection ; hence, the allocation of the 

 name in a restricted sense to the Mexican form, as has been done 

 in my Manual of North American Birds (p. 552), is correct.
