72-121 mm.) resembling Calothorax in the long, slender, decurved 
bill and in coloration, but adult males with tail longer than wing, 
the lateral rectrices rounded terminally and gorget not elongated 
laterally, the adult females with tail deeply forked or strongly 
double-rounded. 
Bill much longer than head, sle der, terete, rather strongly 
decurved; culmen rounded except basally, whcre contracted into a 
rather indistinct ridge; tomia smooth; mandible with the usual 
longitudinal median groove. Nasal operculum broad and strongly 
convex (especially anteriorly) nude, but mostly concealed by the 
decumbent frontal feathering, which extends forward considerably 
beyond anterior end of nostril, forming a short and obtuse point 
or antia on each side of culmen. Tarsus feathered, except on posterior 
and lower portions; middle and outer toes about equal in length, 
the inner slightly shorter, the hallux shorter than inner toe. Wing 
less than twice as long as exposed culmen, the outer primary longest, 
normal in shape. Tail in adult male slightly longer than wing 
(D. eliza) to more than one and a half times as long (D. enicura), 
forked for nearly two-thirds (D. eliza) to more than three-fourths 
its length (D. enicura), the lateral rectrices rounded terminally 
(slightly expanded in D. eliza); in adult females tail nearly two- 
thirds (D. eliza) to more than two-thirds (D. enicura) as long as 
wing, forked (but with third rectrix longest) in D. enicura, strongly 
double-rounded in D. eliza.
