Description, — As in Gates, F. B. I. 



Hab. — Manipur, Cachar, Naga Hills, and Chin Hills on the west of Burma, 

 where it was procured by Col. Rippon on Mt. Victoria, and by Capt. 

 Venning at Haka, and Mr. C. Hopwood, North Chin Hills. 



Stuart Baker says he has found this bird breeding in the higher ranges 

 close to Manipur. It appears to build a very neat and compact nest of 

 the usual type, and generally lays 3 eggs, rarely 2 or 4. These area 

 pale blue, and measure from 1"08" to "98" in length, and from •76" to '78" 

 in breadth.

Gates in F. B. I. draws attention to the differences between birds from 

 difl:erent localities. Dr. Hartert has divided them up into three well 

 marked geographical sub-species. 



This race is noticeable for its more highly coloured upper plumage, and 

 very rufous under parts. 

 Kab. — Nepal. 



Trochalopterum lineatum grisescentior, Hartert. 



The Simla Streaked Laughing Thrush. 



Hartert, Vog. Pal. i., p. 636 (1910). 



The greyer margins of the feathers much wider, and the streaks on the 

 upper plumage much paler. 



Hob. — From Hazara W. Himalayas, Kumaon, Simla, and Southern 

 Kashmir. Also Kohat, the N. W. Frontier, birds from this last locality 

 seem greyer still than typical Simla birds. Capt. Whitehead informs me 

 that this sub-species on the N. W. Frontier leaves the higher ranges in 

 Winter and comes down lower. This is very interesting, and I think if the 

 wings were examined it might possibly show that birds from these localities 

 had a longer wing than the more sedantary races. 



Trochalopterum lineatum gilgit, Hartert. 

 The Gilgit Streaked Laughing Thrush. 



Hartert, Vog. Pal. i., p. 636 (1910). 



Lower plumage greyer and paler; the shafts whiter and frequently 

 terminating in a triangular spot. 

 Hab. — Gilgit and N. Kashmir.
