Viscount Walden on a supj^osed new Sjiecies of Cnchoo. 305 



h. Column yellowish white ; tentacles and disk pellucid white, 

 with a very pale blush of rose when not fully expanded ; 

 radial hands opaque white, very few. [A. single speci- 

 men.) 



Size. 



When fully expanded, from 2 to 5 inches across. 



The whole appearance strongly resembles a Tealia, ; but 

 its almost total want of warts distinguishes it from T. digitata^ 

 another deep-sea species (which I have not seen). It may, 

 perhaps, be a link between Tealia and 8tom])Ma Yax. jyyri- 

 glotta (Gosse, p. 223). 



XXXII. — Description of a supposed new Sjyecies of Cuckoo 

 from Celebes. By Arthur, Viscount Walden, P.Z.S. 



Hierococcyx crassirostris^ n. sp. 



A collection of birds recently made in North Celebes by 

 Dr. Meyer contains two examples of a Cuculine form which 

 appears to be undescribed. They severally represent a di- 

 stinct and very marked phase of plumage. Yet neither can be 

 affirmed to have attained its full livery. One example is in 

 the "hepatic" stage, the other may be wearing the adult 

 garb. 



Example No. 1 , hepatic plumage, has the nape, back, upper 

 tail-coverts, upper surface of the wings, and the quills bright 

 chestnut. The nuchal feathers, which are white at their base, 

 are broadly fringed with black, giving a barred appearance to 

 the nape. The interscapulars are obscurely edged with brown. 

 The shoulder-coverts have black subterminal marks, or are 

 else faintly clouded with black markings. The quills are 

 almost of a uniform chestnut above and below ; subterminally 

 they are more or less clouded with brown. The inner webs at 

 their insertions are pure white, which descends for about one- 

 third of their length. There are no bands or bars pn either 

 surface of the quills. The under shoulder- and tail-coverts are 

 pure cream-colour, devoid of any markings. The middle pair 

 of rectrices are broadly banded with black. The intervals be- 

 tween the black bands, and which are much narrower than the 

 black bands, are bright chestnut on the outer edges, but pure 

 white near the shaft. The two portions of each band divided 

 by the intervening shaft are unsymmetrical. The remaining 

 pairs are also broadly banded with black, but the intervals are 

 less chestnut, becoming nearly all white in the fifth pair. In this 

 outer pair the bands are nearly symmetrical. All the rectrices
