264 ELEMENTS OF ORNITHOLOGY. 
The suborder Zurylemi contains two families, those of the 
Green Broadbills, or Calyptomenide, and those of the Broad- 
bills > par excellence, the Eurylemide. 
The suborder of Humming-birds, Trochili, contains but a 
single family, Zrochilide *, and subfamily Trochiline. 
The second order, Coraciiformes, contains probably more than 
523 species, including the Kingfishers, Swifts, and Hornbills, 
with their allies, and these, again following Mr. Seebohm, we 
group in three suborders, namely, (1) Coracie, (2) Halcyones, 
and (3) Bucerotes. 
The characters of these groups may be thus stated :— 
Order II. CORACIIFORMES. 
Hallux present and connected with the flexor longus digi- 
torum, and not with the flevor longus hallucis; plantar tendons 
not free; no ambiens; young born nearly naked; wing- 
coverts large ; anterior toes united together at the base for some 
distance ; outer toe a little shorter than the middle one, and 
with three joints ; inner (or second) toe either joined to the 
middle one for some distance, or absent ; bill long and tapering ; 
nostrils basal, above the middle of the mandible; tongue not 
extensile. 
Suborder 1. Coracie. 
Spinal feather-tract well defined on the neck, but forked on 
the upper back; oil-gland generally present but not tufted ; 
palate variously formed; a semitendinosus present (except in 
the Swifts) ; ceca present (except in the Swifts) ; basipterygoid
