the Miillerian and Wolffian ducts unite, thus leaving a single duct 

 on each side ; and these unite with one another and with the urethra 

 at the same point to form the rudimentary urogenital chamber. 



It is thus interesting: to observe that the course of the iliiUerian 

 ducts in the voung of the Kangaroo is essentially the same as that 

 in the adult Opossums. 



0. Description of a new Fruit-pigeon of the Genus Caj-po- 

 phaga from the Lonisiade Archipelago. By H. B. 

 Tristram^ F.R.S. 



[Received December 9, 1831.] 



I have lately received from Lieut. G. E. Richards, R.N., a collection 

 of birds made by him in the Solomon Islands, New Britain, and several 

 neighbouring islands. 



The collection from New Britain and the Louisiade Archipelago 

 consists of 62 species. 10 of which are represented in the collec- 

 tion both from Blanche Bay, New Britain, and from St. Aignan's 

 Island, Louisiades. These are chiefly species which call for no re- 

 mark, such as Lorius hypcenoclirous, Esacus magnirostrig, Charadriui 

 fultus. &c. 



But there is one fine Fruit-pigeon which appears to me quite new, 

 and which is represented by three specimens, one male and two 

 females, all from St. Aignan's, Louisiade group. This I propose to 

 describe as 



Carpophaga salvadorii, sp. nov. 



C. capile, collo et thorace paUide vinaceis, annulo alio constricto ad 

 basin eujusque mandibula, pectore et dorso superiors Icete cinaceis, 

 hoc colore sensim transeunte in castaneum quo abdomen et crissum 

 iinguntur ; scapularibus resplendenti-nigris, figuram conspicuam 

 tanquam Y conjunctim formantibua ; alis et dorso inferiore 

 schist aceis : supracaudalibus et cauda nigris ; hac fascia lata 

 alba duos pollices ante terminum instructa j rostro cinereo ; iarsis, 

 pedibus etiride rubris. 

 Long. tot. 16"75, alcB 10'3, caudce 6. 

 Hab. St. Aignan's Island, Louisiade Archipelago. 

 I have named this bird in compliment to Prof. Salvadori, to whom 

 naturalists owe so much for his unwearied labours in elucidating the 

 avifauna of Papuasia. 



C. gahadorii differs from C.pinon, to which it is closely allied, by 

 its rosy-coloured head, while the head of its congener is ashen grey. 

 by the richer maroon colour of its upper back, by its lower back and 

 rump being black instead of slate-grey, and by the light maroon of its 

 upper back becoming more intense as it descends, instead of being, 

 as in C. pinon, vinous shading off into slate-grey. The white tail- 

 band is also much wider. The sexes are identical in plumage.
