266 Zoological Society : — 



This fine species is named Lithodes (Fetalocerus) Bellianus in com- 

 pliment to the ablest of our British carcinologists, the learned and 

 scientific President of the Linnsean Society, Professor Thomas Bell ; 

 in whose fine collection it is preserved. It is to him I am indebted 

 for the loan of the specimen. 



May 27, 1856.— Dr. Gray, F.R.S., in the Chair. 



Mr. Gould brought under the notice of the Meeting a portion of 

 the Birds collected by Mr. John MacGillivray, the naturalist at- 

 tached to H.M. Surveying ship Rattlesnake, and lately sent home 

 by Capt. Denham, the Commander of the Expedition. They were 

 obtained on the Fijis, San Cristoval, Isle of Pines, and other islands. 



Perhaps the most remarkable of these birds is a species of Cen- 

 tropusy which exceeds in size every other member of the genus Mr. 

 Gould has yet seen. The single specimen sent home is not fully 

 adult, as is evidenced by some freshly moulted feathers of the tail 

 and wings differing in colour from the older ones. On account of 

 its large and robust form, Mr. Gould proposes to call this species 



Centropus Milo. 



Head, neck, mantle and breast tawny-white, remainder of the 

 plumage mottled brown and green ; some of the feathers being brown 

 indistinctly banded with green, while others are entirely green, the 

 mottled hue being that of immaturity, and the green the adult 

 livery : bill black. 



Total length, 26^ inches; bill, 2^ inches long by 1^ deep at the 

 base; wing, lOf ; tail, 14^; tarsi, 3. 



Hab. Guadalcanar Island. 



Remark. — The specimen is a male. Unlike the other members 

 of the genus, this species has bare orbits, with the colouring of which 

 Mr. Gould is not acquainted. 



For a fine species of Fruit-eating Pigeon from the Isle of Pines, 

 Mr. Gould proposed the name of 



Ianthoenas hypcenochroa. 



Head, neck, breast, and under surface vinaceous brown, with 

 glossy purple reflexions on the back of the neck, and a slight gloss 

 of the same hue on the sides of the neck and breast ; chin, sides of 

 the face and throat white ; all the upper surface, wings and tail dark 

 slate -grey, the margins of the wing-coverts and the feathers of the 

 back and upper tail-coverts glossed with bronzy green ; bill scarlet 

 at the base, yellow at the tip ; orbits naked and scarlet ; feet red- 

 dish flesh colour. 



Total length, 16 inches ; bill, 1^ ; wing, 9i ; tail, 7 ; tarsi, 1. 



Hab. Isle of Pines. 



Remark. — This is a fine species, about the size of the common 

 Pigeon of Europe. It pertains to the subgenus Ianthoenas^ the mem- 

 bers of which are very nearly allied to the birds constituting the 

 genus Carpophaga.
