Show 604 MR. R. B. SHARPE ON THE CUCULIDAE L*June 17) The sexes differ conspicuously-an unusual character in this subfamily. Genus 5. R H O P O D Y T E S . Type. Rhopodytes, Gib. & Heine, Mus. Hein.Th. iv. p. 61 (1862). R. diardi. Fig. 9. Head of Rhopodytes diardi. The species which I would place in this genus are the following: -typical-R. diardi, R. tristis, R. viridirostris, R. borneensis ; less typical-R. erythrognathus, R. eeneicaudus. 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 developed. All of them have rounded nostrils; but the two last-mentioned birds are scarcely typical, as the hare 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 Phcenicophaes curvirostris, which I make the type of this new genus, bears the greatest resemblance to Rhopodytes erythroyna- Fig 10. Head of Phanicophaes curvirostris. thus, so much that, as Lord Walden has pointed out, they are scarcely to be separated specifically, I must point to the well-marked structural difference of the nostril as a good generic character.
