The ribs are beautifully ornamented by three rows of close, sharp, 

 erect, slightly curved scales. 



Mr. Sowerby also characterized a new species of Rostellaria.

The whorls of this species are flatter than in Rostellaria curviros- 

 trum ; the last whorl is much shorter and the anterior canal is straight. 

 The outer lip being irregular, led me at first to suppose that the spe- 

 cimen from which the description is taken might be one of the com- 

 mon species in which the completed aperture had been prematurely 

 formed, it being well known that R. curvirostrum, in a young state, 

 has the beak straight. But a slight difference in the shape of the 

 whorls, the broad chestnut bands on the upper part of them, and the 

 fact of several other specimens precisely similar having been seen by 

 Mr. Cuming at Berlin, have determined me to describe this as a new 

 species, which I now do with little hesitation. 



Mr. Gould exhibited a new species of Parrot belonging to the 

 genus Coryphilus, whch he characterized as follows : — 



CoRYPHiLus Dryas. Cor. vittd frantali metallice viridi, ccerulc' 



scente verticem versus ; hujus plumis elongatis et saturate caruleis ; 



dorso et alis obscur^ viridibus, urapygio, cauda tectricibus, et crisso 



pallide viridibus, caudce rectricibus albis, marginibus pallide vire- 



scent'i-caruleo tinctis ; loris albis, pectare vittd saturate cccruled 



ornato ; abdomine albo, femoribus saturate cceruleis. 



A band of verditer- green crosses the forehead, changing into blue 



towards the crown, the feathers of which are lengthened and of a 



deep blue, with a narrow line of shining paler blue down the centre 



of each ; back and wings dull verditer-green ; rump, upper and under
