Mr. Stuart Baker also described the following; new 

 genera, species, and subspecies from a collection of birds 

 collected by Mr. E. G. Herbert in Siam : — 



Nigravis herberti, genus et sp. nov. 



Whole plumage very dark rich brown ; the crown, fore- 

 head, lores, and a line under the eye black ; the shafts of 

 the crown-feathers highly glazed and showing up well. 

 Tail black showing very faint narrow bars in certain lights ; 

 chin and throat paler and upper breast tinged with grey 

 owing to the grey bases of the feathers showing through. 



" Eyes brown ; beak bluish white ; legs and claws 

 blackish brown'' {Herbert). 



Length of wing 78 mm. ; tail, central tail-feathers 72 mm., 

 outermost 56 mm.; bill at front 18 mm. ; tarsus 28 mm. 



This bird undoubtedly belongs to the Timeliidce, or Tur- 

 doidce ds they must now be called, but I know of no genus 

 in that family with which it can be placed. The wing is 

 typically rounded, the first feather being about half the 

 length of the 6th and the 6th to the 10th are subequal and 

 longest, whilst the outermost secondary is only 2 mm. shorter. 



The tail-feathers are broad and graduated and the tarsus 

 fairly stout but not very long ; the bill is like that of 

 ^^thostoma {^lurdinus), but the nostril is completely covered 

 by an operculum, and the feathers on either side of the base 

 of the bill grow right up to the posterior edge of the nostril. 

 There are three very short rictal bristles and the feathers of 

 the chin have fine hair-like tips.
