IIR MR. O. SALVIN ON ORNITHOPTERA VICTORI.E. [Feb. 7, 



No. 13. Bahalla Island, off Sandakan HarI)our, contains both 

 black and white nests, the collection of them being farmed out by 

 Government. The apertures are in the face of a precipitous sand- 

 stone cHff, some 600 feet high, and are entered from the summit, 

 the climbers being lowered down from the top by ropes. 



No. 14. Ulu Sembakong Caves. Natives informed me of some 

 valuable caves on the Sembakong River, which empties itself into 

 Sebuco Bay, East Coast ; these could only be visited by goinj^ 

 through the country with an armed force, as some of the head- 

 hunting tribes are hostile. 



No. 15. Some caves at Waleigh-waleigh, Kinoram E-iver, a 

 tributary of the Bongon River, a part of the northern Kinabalu 

 watershed ; these were visited some years ago by the late Mr. 

 Frank Hatton. 



No. 16. Mantanani. Tbese caves are situated in a group of 

 uninhabited islands of that name, about 20 miles off the north-west 

 coast of Borneo. Both white and black nests are taken, the collec- 

 tion being in the hands of two Borneo tribes who collect in alternate 

 seasons. 



I have now enumerated all those caves that are known at present. 

 Doubtless this vast territory contains others perhaps richer than 

 these, and in the course of time, when the country is more fully 

 explored, we shall be able to fix their position definitely on the map 

 of British North Borneo. 



6. A Note on Oniithoptera victoria, Gray. 

 By OsBERT Salvin, M.A., F.R.S. 



[Eeceived February 7, 1888.] 

 (Plate IV.) 



At the meeting of the Society held on the 1st of March last I had 

 the pleasure of exhibiting a male specimen of an Ornithoptera, from 

 tbe island of iNIaleita, one of the Solomon group. This specimen 

 Mr. God man and I considered to belong to the male of the long- 

 known 0. victorice, the description of which was based upon a female 

 example obtained by J. Macgillivray, but of which the locality was 

 not recorded. The females, of which specimens were also exhibited, 

 from Maleita Island agiee with the type, hence our determination 

 of the male. The male and the underside of the female have since 

 been figured by Mr. Henley G, Smith, on the first plate of his new 

 work ' Rhopalocera Exotica,' the male having been described in 

 the June number of the ' Annals and Magazine of Nat. Hist.' of last 

 year (1887). 



Mr. Woodford, the enterprising naturalist who captured these 

 specimens, has since returned to England, bringing with him a large
