Beddard, F. E. Nqte on the Air-sacs of the Cassowary. P. Z. S. 1886, 
pp. 145 & 146. 
The author finds that theMiitherto undescribed respiratory organs of 
Casuarius rosemblo those of Apteryx rather than those of Rhea, tho 
differences consisting in tho position- and slope of the dissepiments, and 
in the shape and size of the air-sacs, &c. The conclusions he draws are 
that Casuarius is near Apteryx , and that Dromceus should be separated 
from the former, and placed nearer Rhea and Struthio . 
. On the Syrinx and other Points in the Anatomy of the Capri - 
mulgidce. T. c. pp. 147-153, 3 cuts. 
The author begins by stating that Steatornis is a most remarkable 
genus, and is parallel, with regard to its bronchial syrinx, to Crotophaga 
( Cuculidce ), though differing in certain details. Ho says that in tho 
Caprimidgidce the variation of structure of the syrinx is parallel to that 
of Cuculidce , and that, as in the latter \cf. Zool. Rec. xxii, Aves, p. 50], the 
family may be divided into 3 types — (i.) Caprimulgus , Chordeiles , Nycti- 
dromus, GEgotheles (where the syrinx is tracheo-bronchial) ; (ii.) JBatra- 
chostomus, Podargus (where it is intermediate between the above and 
Steatornis, though nearer the latter) ; (iii.) Steatornis (where it is purely 
bronchial). He passes over Caprimulgus and Chordeiles, as being already 
known, and describes the syrinx in the other five genera (cuts of first 3). 
Remarks follow on the visceral anatomy \_e.g. y QZgotheles differs in having 
no coeca, Chordeiles in having no gall-bladder], and on the Myology
