164 JANTHOTHORAX BENSBACHI. 



and breast purplish blue, the feathers on the chest closely 

 set and rounded at the tip , the breast-feathers much longer ; 

 under wing-coverts, abdomen, vent and under tail-coverts 

 earthy brown ; from the flanks springs a very rich tuft of 

 straight egrettiform feathers, earthy brown on the basal, 

 sooty brown on the terminal half and reaching beyond the 

 outer tail-feathers. The basal half of the feathers in the 

 whole plumage of this bird is earthy brown. Jris red 

 (Bensbach), bill and feet black. Wing 20 cm.; tail 13, 

 central pair 22 ; culmen from base of skull 4,8 ; tarsus 4,2. 



Habitat: Mounts Arfak , N. W. New Guinea. 



This species has its nearest allies in the dark-colored 

 genus Craspedophora , and its bill does not differ much in 

 shape and size from that of C. intercedens. The distribution 

 of the metallic colors, however, is quite different. A re- 

 gular breast-shield is wanting , and the flank-tufts , bent 

 downward in Craspedophora , are straight. The most striking 

 difi'erence is found in the narrow, straight and very long 

 central tail-feathers , a characteristic which , as already said , 

 it has in common with Lamprothorax Wilhelminae Meyer, 

 This latter species , however , is related with Lophorhina , 

 and is showing no aflSnity whatever with Craspedophora. 



I am much pleased to name this species after Mr. J. 

 Bensbach , who kindly presented our Museum with the two 

 new species of Paradise-birds. 



Besides these two species the Leyden Museum recently 

 obtained a third species, also from the Mounts Arfak, which 

 turns out to be the above mentioned 



Lamprothorax Wilhelminae A. B. Meyer.

Our bird fully agrees with Dr. Meyer's typical specimen 

 and shows, like the latter, some remnants of the immature 

 plumage. The two long central tail-feathers are straight
