Var. a. Flava, castaneo-vittata. 



In this pretty variety a single chestnut band borders the base of 

 each whorl, and on the body- whorl there is in addition a broad, sub- 

 central, chestnut band. 



Var. b. Castanea, albo vittata. 



In this variety the rich chestnut is relieved by a white band that 

 borders the upper part of the last two whorls, near the suture. 



Var. c. Castanea, fusco vittata. 



In this variety the upper part of each whorl near the suture is 

 banded with brown.

Hitherto this form has only been discovered in the Western World. 

 Mr. Cuming received the specimen above described from a captain 

 of a ship, who said he had got it from a native of one of the Feejee 

 Islands. A glance at the western species will satisfy the observer 

 that the species above described is distinct. — W. J. B. 



Mr. Waterhouse exhibited two new species of Birds from the So- 

 ciety's collection, and pointed out their distinguishing characters. 

 The first is a small species of Pints, believed to be from the north- 

 west coast of South America, and is remarkable for the absence of 

 spots and markings, and the brilliant red colour of the upper parts 

 of its body and wings : this red colouring commences on the back of 

 the neck, and is continued to the tail, as well as over the whole of 

 the wings ; that is, over the visible portion of each feather, the inner 

 shafts being of a brown colour. The whole of the upper surface of 

 the head is of a brown-black colour ; the sides are pale brown ; the 

 throat is pure white ; the chest and whole of the under parts of the 

 body are of a dirty white colour, indistinctly tinted with yellowish. 

 The tail is of an uniform blackish brown colour, with the exception 

 of the two outer feathers on each side, which are pale brown ; on 

 the apical half of the external feather there is a very obscure indi- 

 cation of bands. The beak is of a very pale horn-colour. 



The principal characters may be thus Ijriefly exi:)ressed : — 



Pious CALLONOTUS. Pi. cttpite pallide fusco, supra fuliginoso ; 



corpore supra alisque sanguineis ; guJd,pectore abdomincque albes- 



centibus ; caudd obscure fused ; rostro albescente. 



In size and general form this species agrees very closely with the 



Pieus minor of Europe, but its beak is rather longer in proportion, 



being nine lines in length. 



The second new species is one of the Icterine group, and in most
