or minutely striated. Colour yellowish-olive, painted more or less 

 with wavy, dark brown longitudinal lines. Aperture pinkish-white, 

 occasionally having the outer lip dotted with dark pink-brown marks. 



Hub. Same as P. sidcatus. 



This is a rare shell, if really distinct from sidcatus, from which 

 and from reyalis it may at once be distinguished by the shallowness 

 and irregularity of the ridges. 



Anculotus carinatus, Layard. 



Shell somewhat globose ; axis 5 lines, diam. 4 lines. Spire ex- 

 serted, short. Whorls inflated, rather square, sharply keeled round 

 the inferior angle, minutely longitudinally striated. Colour dull 

 olive, marked faintly with two or three broad bands of dark rufous- 

 brown, which are very apparent in the aperture ; columellar lip 

 white, stained with a light dash of the same rufous-brown on the 

 exterior margin. 



Hab. Streams in the Mahakeshwar Hills, Bombay Presidency. 

 Mus. Cuming. 



March 28. — Dr. Gray, Vice-President, in the Chair. 



Mr. Gould exhibited male and female specimens of a very rare 

 English Duck, described in 184/ by Mr. Bartlett, under the name 

 of FuUgula ferino'ides. The specimens exhibited were lent to Mr. 

 Gould by M. Van den Bergh, of Rotterdam. Mr. Gould men- 

 tioned, that only three instances of the occurrence of the bird in 

 England are on record ; one of the specimens is in the collection of 

 J. H, Gurney, another in that of Mr. Doubleday, of Epping, and 

 the third in the museum of the late Earl of Derby, at Liverpool. 



Characters of some New or imperfectly-described 



Species of Tanagers. 



By Philip Lutley Sclater, M.A., F.Z.S. 



I have been collecting Tanagers for some time, with the view of 

 ultimately attempting a monograph of the family. But the forms in 

 many of the genera are so closely allied, and the limits of the family 

 itself at present so unsettled, that a larger collection of species, and 

 a much greater familiarity with the subject-matter than I have yet 

 had time to acquire, are requisite before such a monograph can be 

 satisfactorily completed. Puzzling indeed to ornithologists would 

 seem the question, " What is a Tanager ?" as puzzling perhaps as to 

 political economists Sir Robert Peel's celebrated poser, " What is a 

 pound?" My ideas on this point, that is, I mean, as to the posi- 

 tion and extent of the family or subfamily of Tanagers, coincide, I 

 believe, nearly with those of Mr, G. R. Gray. 



ATanager I consider to be a dentirostral Finch — to be distinguished 

 from other more ty})ical FriuyUlidce by the presence of one or more 

 teeth or notches in the u})per mandible (sometimes further developing 

 themselves into serrations, as in certain species of Euphonia and Ta- 

 cky j)honiis), and the culmen being always more or less inflexed, never 

 straight. The colours of the grouj) are generally very brilliant. They
