In this portion of his excellent catalogue the author includes, 
besides the Bpheniscid(By the families Colymbida, PodiclpidcBy 
and Alcid(By under the common name Urinatores — an arrange- 
ment, we think, not to be followed, and one which, when we take 
into consideration the fact that he subdivided a preeminently 
natural family like the Falconidce into no fewer than nine groups, 
we cannot but regard as illogical. Heliornis (including Podica 
and Podoa) is also placed here, notwithstanding that its anatomy 
(Brandt, Beitr. zur Kenntniss der Naturgesehichte der Vogel, St. 
Petersburg: 1839, pp. 117-122; and Jerdon, B. Ind. hi. p. 721) 
and habits (Blyth, J. A. S. B. xxviii. p. 415, and Tickell, tom, cit. 
p. 455) have been shown to be essentially those of t\iQ Rallidce,
