MK. R. B. SHARPE ON THE CUCULID.E 



June 1 7, 



The sexes differ conspicuously — an unusual character in this sub- 

 family. 



Genus 5. Rhopodytes. Type. 



Rhopodytes, C ib. & Heine, Mus. Hein.Th. iv. p. 6 1 ( 1 862). R. diardi.

The species which I would place in this genus are the following : 

 — typical— R. diardi, R. trisiis, R. viridirostris, R. borneensis ; 

 less typical — R. erythroynuthus, R. ceneicaudus. All these have 

 stiff bristles on the forehead, and the bare face is highly rugose : in 

 R. diardi the bristles on the head and neck are wonderfully de- 

 veloped. All of them have rounded nostrils ; but the two last- 

 mentioned birds are scarcely typical, as the bare face extends to the 

 nostril, and is not separated, as in R. diardi, by a narrow loral line 

 of feathers. It is possible that a comparison of the birds in spirits 

 would discover other differences. 



Genus 6. Rhinococcyx, gen. nov. 



Although Phamicuphaes curvirostris, which 1 make the type of this 

 new genus, bears the greatest resemblance to Rhopodytes erythroyna-

thus, so much that, as Lord Walden has pointed out, they are scarcely 

 to be separated specifically, I must point to the well-marked struc- 

 tural difference of the nostril as a good generic character. The out-
