from its as.soeiate.s in the g-eniis Xi/lohvcco [^Barhatula), and to 

 unite it generically witii the species of the ocnera StocfolcHina and 

 SniHorhfx under the name IhK-cdtKHloit llartlaub." He bases this 

 s("i)arati()n of I>. dur/ia!ll n! U\m\ Xi/lohiicco apparently on the suppo- 

 sition thiit this species has the pro])ortion of the toes dift'erent from 

 that ohtainino- amono- the species of XijlohKcco^ and like that found in 

 SniHoj'hJs and Sf(tcf(>l;i^ni<i, i. e., the tirst toe about ecjual to the half 

 of the fourth; but in all i\\o full ij (i<h(ll and otherwise perfect speci- 

 mens of ihic'iullhii (examined by us the length of the tirst toe is 

 decidedly less than half the fourth, and thus exactly as in Xylohucco^ 

 thouo-h curiously enough in one or two examples that are apparently 

 innnature the proportions of the tirst and fourth toes are as in Sriiilo- 

 rh.'ix and Sfdctohenta. As there are al)Soliitely no other characters to 

 separate (htchaUlnl from Xylohucco, it must l>e replaced in that group, 

 and the two generic names founded upon it, Biiecanodon Ilartlaub" 

 and Claihinix Reichenow/-' be entered as synonyms under Xijlohucco. 

 Both Siiulor/u.s and SfactoJa'nia are perfectly good genera, as Doctor 

 Sharpe has always consistently claimed, and there seems to be no good 

 reason for uniting them as Doctor Keichenow has done. Their char- 

 acters, as well as those of the two othei- genera here involved, will 

 appear in the following diagnoses: 



I. Stactolaema. 



St(«i()l;vma Marshall, Proc. Zool. Soc Loud., 1870, p. ILS (type, Bucamodon 

 ancliii'tn' t^oeage). 



Bill large and swollen, the cidmen curved, witli no conspicuous 

 ridge; rictal and frontal bristles few or none, and, if present, very 

 weak; no naked space surrounding the eye; secondaries falling short 

 of the primari(>s by not more than two-thirds of exposed culmen; first 

 toe a))Out ecpial to half the fourth. 



The species of this genus are:

Bill large and turgid, the culmen curved thrcnighout, with a con- 

 spicuous crest on its basal portion; rictal and frontal l)ristles fairly 

 well developed; an unfeathered s])ace around the eye; secondaries 

 short, the ditierence between their tijjs and those of the primaries 

 more than the length of exposed culmen; tirst toe about equal to the 

 fourth.
