4 PEOCEEDINGS OP THE jSTATIONAL MUSEUM vol. 77 



Of the islands here considered, all are within the 100-fathom line, except 

 Maratua and Kakaban, which appear to be volcanic. These two islands are 

 beyond the Sunda Shelf. Of the islands connected by shallow water with the 

 mainland of Borneo, all appeared to me to be built up from coral reefs, except 

 Pulo Pandjang and Pulo Raboe Raboe. On these two islands there were 

 deep yellow or golden-colored soils in places, much resembling those of the 

 nearby mainland of Borneo. 



It was the original intention to have Dr. Harry C. Oberholser 

 work up the Bornean collection as a whole, in conjunction with col- 

 lections previously made in that general area by Dr, W. L. Abbott, 

 but owing to his other duties progress in this has been slow. In 

 view of his preoccupation in other matters I have been requested to 

 report on the birds collected by Raven on the smaller islands sepa- 

 rately. In a preliminary paper ^ I have named one form from Mara- 

 tua and two forms occurring on Maratua as well as some of the other 

 small islands of this part of the Bornean coast. Of all the islands 

 visited Maratua is the only one that has developed a more or less 

 peculiar avifauna. This is not remarkable, as it is the only island 

 of any size amongst those visited by Raven and lies outside the 

 Sunda Shelf. 



Doctor Oberholser had used Raven's material in revisionary work 

 or the description of new forms, but in the case of the kingfishers of 

 the genus Sauropatis ^ the names of the small islands in the bay at 

 Maratua were used and their connection with that island lost or 

 buried. 



The present paper contains a list of all the birds collected by 

 Raven on these small Bornean islands. Outside of the novelties 

 found on Maratua there are several records of forms that have never 

 been taken on the main island of Borneo before to my knowledge. 



All measurements in this paper are in millimeters. 



I am indebted to Mr. Raven for making the map to accompany 

 this article.
