With regiml to ilie "species" fouuded by Messrs. Miller and 

 Lyoii, we cau ouly reiterate our opiuiou that the majority of them 

 should have been called sub-species rather than species. Their dif- 

 ferences are, for the most part, average differences, based on series, the 

 series overlapping in the characters used, and therefore, even though 

 insular in locality, trinomials, and not binomials, might well have been 

 used for them as indicating the nearness and more or less inconstant 

 nature of their relationship to older known forms. 



In conclusion, we would express our appreciation of the public 

 spirit and sympathy for science shown by the authorities of the 

 Federated Malay States, who have permitted the party the use of a 

 specially-chartered vessel for these explorations, and have therefore 

 helped materially in carrying out this extensive collecting trip. Of 

 these authorities the names of Sir John Anderson, g.c.m.g., Governor 

 of the Straits Settlements, and High Commissioner for the Federated 

 Malay States ; Sir William T. Taylor, k.c.m.g., Eesident- General, 

 Federated Malay States ; and H. C. Belfield, Esq., c.m.g., Eesideut of 

 Selangor, who was officiating as Resident- General at the time the Rhio 

 expedition was projected and carried out, should be specially mentioned. 

 Thanks are also due to H.H. the Sultan of Johore for facilities 

 afforded in his territories and to Mr. H. Spakler, Cousul-General for 

 the Netherlands, for providing introductions which were of much 

 assistance in islands under the Dutch Flag. 



[The whole of the collections reported on in the present article, with 

 the exception of those from Selangor and Perak, were made during a 

 cruise, which lasted from the commencement of June, 1908, to the 

 4th September, 1908. The vessel used was a large Chinese tongkaug, 

 or sailing lighter, of about 70 tons measurement, which had formerly 

 been used for conveying granite from the quarries of Pulo Ubin 

 in Johore Straits to Singapore. She measured about 70 feet in 

 length by 16 feet beam and drew when running light, as we used her, 

 about 5 feet. She was ketch rigged and carried a crew of four Hokkien 

 Chinamen and on a good breeze we could get six or seven knots out of 

 her, though, with the light airs prevalent at the season, our progress 

 was usually very slow and we took six days returning from Pulo 

 Tinggi to Singapore Straits, a distance we had covered on the north- 

 ward journey in 18 liours. 



Our party consisted, for the greater portion of the trip, of two 

 Europeans, four Dyak collectors and a couple of Malay servants, 

 \mt Karimon and Kundur were not visited by Robinson, who had 

 to return to Kuala Lumpur. We lived on board the tongkang, in 

 ^vhich a comfortable and commodious cn.bin had been built amidships, 

 collected from dawn until about 9 a.m. and again from 4 p.m. until dusk, 

 the intervening time being spent in skinning. We secured in all 

 i-ather over a thousand mammal skins and about two hundred birds. 

 The latter, however, are of no particular interest and only include one 

 rarity, the pigeon Cohonha grisea, G. K. Gr., ^vhich was shot on
