34 MR. p. L. SCLATER ON TRAGELAPHUS GRATUS. [Feb. 6, 



island. The absence of any spot on the nape, the pure cinnamon of 

 the back and wings, and the different colour of the lower back and 

 rump render it at once distinguishable from either of its congeners. 

 We propose to describe it as follows : — 



OtIBIPHAPS INSULARIS, Sp. UOV.

 interscapulio, secundariis et tectricibus alarum omnibus pure

 ( Goldie). 



Obs. Ab O. nobili crista occipitali et macula nuchali absentibus, 

 colore dorsi purius cinuamomeo nee purpureo tincto, colore dorsi 

 postici viridescente nee onniino purpureo, et cauda breviore diversus. 

 Ab O. cervicali macula nuchali absente, colore dorsi purius cinua-

Mr. Goldie writes that he obtained the two specimens of this 

 Pigeon on an exceedingly rough range of mountains at an altitude 

 of over 2000 feet on Fergusson Island, one of the Dentrecasteaux 

 group. The call, he says, is a sort of ke-o, the " o " being pro- 

 longed. One bird was shot on a low limb of a large tree. He adds 

 that the iris is red, and the legs claret-colour with the scales of light 

 greenish yellow. 



Tlie two previously known other species of Otidiphaps have 

 recently been described, and a full account given of them, by Count 

 Salvadori in the third part of liis ' Ornitologia della Papuasia e delle 

 Molucche,' pp. 188-191. The discovery of a third species of this 

 remarkable genus is of great iaterest, and does credit to Mr. Goldie's 

 industry. 



It was on the same island that the Bird of Paradise which we 

 have recently described (Ibis 1883, p. 131) as Paradisea decora was 

 obtained.

(Plate VIII.) 



At the meeting of this Society held on the loth of June 1880, I 

 exhibited a skin of an Antelope from the Gaboon, which I referred 

 to an undescribed species of Tragelaphus allied to TV. speMi, and 

 proposed to call Tragelaphus grafusK I have now the pleasure of 

 being able to give some further information respecting this interesting 

 animal.
