Tyrannula stolula, var. dommicmsts, from Eastern St. Domingo, is described - 
as differing from T. sagrce and T. hahamensis in the distinct yellow abdo-

Tyranniscus gracilipes is an undescribed species from Pebas in Eastern

bling M. chrysoccplialus (Tsch.) from Peru; but that has a stouter bill, the 
feathers surrounding the crest and on the sides of the head are of a clear ash- 
colour, the throat is buff, and the breast-feathers are olivaceous in the mid- 
dle. G. N. Lawrence, Ann. Lyc. N. York, 1867, p. 470. [It is probably

The species so termed are those belonging to the group sepa- 
rated by Bonaparte as Otomela (11. Z. 1853, p. 436-438), a name 
which the author does not adopt. In this group the males have a 
plumage similar to that of the females of Lanius collurio and L. 
bucephalus ; and their relationship to the first shows itself most in 
L. cristaius. The species of the group have all rufous tails and 
no white speculum on the primaries ; but they are also in great 
confusion, which the author has successfully, as it seems to us, 
reduced. Eight species are referred to it, and their synonymy 
and tables of dimensions of specimens from various localities 
are given in much detail. All but one belong to the Indian
