and of the inferior wing coverts, and is very accurately represented by M. 

 Malherbe, (pi. 40). 



28. Campephilus albirostris, (Vieillot.) 



Amongst numerous specimens of this species in the Acad. Mus., there is 

 one which presents some differences in color, and may not be quite identical. 

 It is a female specimen, rather smaller than the females of C. albirostris, and 

 has the black of the breast more extended downwards ; the under tail coverts 

 are blacker, and the shafts of the tail feathers are clear lustrous black. This 

 specimen is labelled "Columbia," and was obtained in Europe for the 

 Academy by Dr. Thomas B. Wilson. 



29. Campephilus trachelopyrus, (Malherbe.) 



This species is singularly nearly related to C. rubricollis (Boddaert), but 

 does persistently retain one valid and reliable character. In C. rubricollis the 

 inner icebs of the longer primaries (only) are fine yellowish-brown or bay color, 

 while in C. trachelopyrus that color in the same feathers extends to the outer 

 web also. In the latter species there is, on this account, on the closed wing a 

 longitudinal band of that color, perhaps not sufficiently conspicuous in M. 

 Malherbe's figures of the male (pi. 8, fig. 2).

Although in his description here cited, Professor Baird relies mainly on the 

 fact that this species has a transverse stripe of red on the nape, I suspect 

 that character to be not the most reliable, though the species I regard as en- 

 tirely valid. One specimen in the Academy Museum, which was received in 

 the Massena collection in 1847, is, I think, clearly this species, though the 

 nape is merely dull white, as in S. varius. This bird is very handsomely 

 figured in Professor Baird's plate above cited, and the distinction between it 

 and S. varius can be seen with the utmost readiness. 



31. Sphyrapicus thyeoideus, (Cassin.) 



Picus thyroideus, Cass., Proc. Acad. Phila., 1851, p. 439. 



Malh. Mon., pi, 38, fig. 1. Cass., B. of Cal. and Tex., pi. 43. 



Formerly a very rare species, this bird has been found recently in more 

 considerable numbers at Fort Crook, Northern California, by that true lover 

 of Natural History and industrious collector, Capt. John Feilner, of the U. S. 

 Army. The figures above cited seem to be either females or young males. 

 The most mature of Capt. Feilner's specimens are probably adult males, and 

 only differ from the females in having a few red feathers on the throat, and 

 the rather deeper yellow of the abdomen. 



32. Sphyrapicus Williamsonii, (Newberry.) 



Picus Williamsonii, Newb., Rep. Pac. R. R. Surv. and Exp., vi. p. 89. 



Malh. Mon., pi. 36, fig. 4. Baird, B. of N. A., pi. 34, fig. 1. 



This very handsome bird, also, has been obtained by Capt. Feilner at the 

 locality mentioned in the preceding article, and it is probably of not uncom- 

 mon occurrence in North-Eastern California.
