“That we have not to deal with an albino is evident not only from 
the color of the eyes, but also the character of the whole plumage, the 
white color having a normal appearance, while the dark colors are 
deep and distinct. 
‘“ After due consideration, I come to the conclusion that the present 
species is sufficiently distinct from H. leucocephalus, and consequently al- 
so from H. albicilla. There are two other species, however, of which I 
know only the names, viz, H. lewcoryphus (Pall.) and H. leucogaster (Gm.); 
but Dr. Dybowski, who is well acquainted with the former, asserts 
that it is quite a different bird, while Dr. Henry Guillemard, who has 
collected in Central Africa, and is autoptically familiar with the latter, 
repeated the same assurance when seeing my bird during a day’s visit 
here. Both received the impression that the species is still an un- 
known one.” 
It is, perhaps, needless to remark that Dr. Stejneger’s bird is very 
distinct from both H. lewcoryphus and H. leucogaster. 
2. ACROCEPHALUS DYBOWSKII Stejneger, MS. 
Sp. cH.—Adult $ (No. 89151, Petropaulovski, Kamtschatka, July 5, 
1882). Above, rather light olive-brown, more decidely olive, or some- 
what tinged with russet, on rump and tail, and slightly more grayish 
across nape; a distinct superciliary stripe of pale buffy-grayish, paler 
anteriorly; a rather indistinct gray loral streak, and a narrow brown 
postocular streak along upper edge of auriculars; auriculars, sides of 
neck and breast, and entire sides, light grayish-olive, the first very nar- 
rowly and indistinctly streaked, especially anteriorly, with white; re- 
maining lower parts dull white, very faintly shaded across jugulum 
with pale brownish-gray; crissum, buffy-white, and flanks tinged with 
deeper buff. Tail much graduated (the lateral feathers .65 of an inch 
shorter than the intermediz), all the rectrices showing indistinct, faintly 
darker bars, the inner webs (except of middle feathers) decidedly darker 
than the outer, and the four outer pairs distinctly tipped with pale 
grayish, becoming nearly pure white on tips of inner webs, these pale 
tips growing gradually narrower toward middle feathers. Maxilla dark 
brown; its edge, with the mandible, pale-brownish (in dried skin), the 
base still paler; ‘‘iris hazel”; legs and feet pale flax-brown (in dried 
skin), the toes slightly darker. Wing 2.85, the secondaries 2.15; third 
quill longest, second and fourth equal; tail 2.40, culmen (from frontal 
feathers) .48, bill from nostril .31, tarsus .90, middle toe .60. 
Dr. Stejneger sends the following interesting account of the habits of 
of this species: 
“The loud song, consisting of the syllables wit’she-wit’she-wit’she-witsh,, 
and somewhat resembling the sound made by whetting a scythe, was 
heard, especially towards night, from all sides, among the high grass 
and willows which cover the swampy slopes of the mountains with a 
thicket almost impenetrable to both foot and eye. It was but seldom I
