same two officers were deputed to investigate the course of tlie 

 Uiliong and to verify its identity with the river known in Tibet 

 as the Tsang-po.* In the course of this journey Captain Bailey 

 was able to secure a few fragmentary botanical specimens and 

 some ripe seeds. The specimens include four species of 

 Mecono^sis, all of them distinct from the one raised in 1914 in 

 Greenwich Park. Two of the four were collected in July, 1913, 

 m the upper Eong-chu Valley, in the extreme east of the 

 province of Kongbo in South-Eastern Tibet, between the 94° 

 and 95° meridians. The other two were obtained in September, 

 1913, near the 92° meridian, in the district of Tawang, 

 in the Tibetan province of Monyul. The district in which 

 these September specimens were collected, though politically 

 Tibetan, belongs geographically to the Himalayan region, 

 and bears to the country inhabited by the Akha tribes approxi- 

 mately the relationship which Chimdro bears to that in which 

 the Abors dwell. All four differ from every species of Mcconopsis 

 hitherto recognised by certain well-marked characters, but, 

 having regard to the meagre and incomplete nature of the material 

 available, it has been thought preferable for the moment to ex- 

 clude two of them from our key to the species and to refer to them, 

 as varieties, under the two fully-known species to which they 

 seem respectively most nearly allied. The remaining two, despite 

 the imperfect nature of the specimens, exhibit, however, features 

 so distinctive that there is no room for doubt as to their claihi 

 to specific rank or for uncertainty as to their position in the 

 genus. So far only one species of Meconopsis raised from seed 

 obtained by Capt. Bailey during this journey has flowered. 

 The seed was gathered on Pen-la, 17,000 ft._; the plants raised 

 prove to belong to the Kepalese and Sibkim species. M.
