156 SMITHSONIAN MISCELLANEOUS COLLECTIONS [voL. 48 
Type.—Haematornis flavicollis SwAINSON. 
This genus is superficially close to Thescelocichla, but aside from 
the lengthened, conspicuously operculate nostrils, by which it may be 
readily distinguished, it has a somewhat shorter tail, and a much 
more arched bill. 
The four forms here referred to this genus are apparently only 
subspecifically distinct : 
Atimastillas flavicollis flavicollis (Swainson). 
Atimastillas flavicollis shelleyi (Neumann). 
Atimastillas flavicollis pallidigula (Sharpe). 
Atimastillas flavicollis tlavigula (Cabanis).

Pyrrhurus Cassin, Proc. Acad. Nat. Sci. Phila., 1859, p. 46 (type Phyllas- 
trephus scandens Swainson) (nec Pyrrhura Bonaparte). 
Chars. gen.—Similar to Bleda, but nostrils lengthened, conspic- 
uously operculate; rictal and nasal bristles weaker; culmen curved 
from base; gonys only slightly ascending ; bill shorter, somewhat de- 
pressed, its height less than its breadth at base, its height at base 
more than one-third the exposed culmen; tarsus about 1% times the 
length of exposed culmen. 
Description.—Tail about nine-tenths of wing, or slightly more; 
throat feathers not lengthened ; tarsus scutellate ; wing 4 to 41% times 
the tarsus; tarsus 1% to 134 times the exposed culmen; head not 
crested; nuchal hairs rather long, much branched; rictal bristles 
rather weak, not reaching half the length of the bill; bill of moderate 
length, somewhat depressed, higher than broad at anterior edge of 
nostrils, broader than high at base, the height at base more than one- 
third the exposed culmen; culmen curved almost from base; gonys 
but slightly ascending; maxilla with but one subterminal notch; 
nostrils lengthened oval, operculate throughout; frontal feathering 
not extending beyond posterior edge of nostrils; nasal bristles few 
and rather short. 
Type.—Phyllastrephus scandens SwAINSON. 
Captain Shelley has united Ptyrticus Hartlaub with the present 
group,” but an examination of even the description and figures of 
Ptyrticus® seems quite sufficient to indicate that it is very different; 
furthermore, it apparently does not belong in the same family! 
This genus was long ago named Pyrrhurus by Cassin,* but
