Whether Williamson's ^^ record of G. crispifrons from the Muang 

 Song Forest, Prae, belongs to this form or not, it is impossible to say. 



The two males from Hin Lap measure: Wing, 75-78; tail, 68-70; 

 culmen, 17-18 mm. The single female: Wing, 72; tail, 64; culmen, 

 16.5 mm. 



CORYTHOCICHLA BREVICAUDATA VENNINGI (Harington) 



Turdinulus hrcvicaudatus venningi Harington, Bull. Brit. Orn. Club, vol. 33, 

 p. 44, 1913 (South Shan States). 



Two males, Fang Meton, Doi Nangka, May 4 and 6, 1931. 



This is a larger form than C. h. leueostida and has the breast and 

 belly tawny without any whitish to the center of the breast. It is a 

 very distinct form. 



Deignan" obtained three specimens on Doi Angka, 4,900-5,500 

 feet, April 22, 26, 1931 ; de Schauensee -^ took two females at Chiengdao 

 at 3,000 and 5,000 feet that he identifies as C 6. hrevicaudata, but they 

 are probably this form. He had no comparative material and neither 

 have I, but my two specimens agree with the description and measure- 

 ments of venningi better than thoy do with brevlcaudata. Two closely 

 related forms would hardly occur in the same area. Deignan ^* 

 records two from Doi Sutep. 



The two specimens collected by Dr. Smith measure: Wing, 66-69; 

 tail, 54=(one imperfect); culmen, 16.5-17 mm. De Schauensee gives 

 the measurement of the wings of his two females as 66 and 64 mm. 

 These are rather small, but they are females. The South Shan States 

 are nearer geographically. 



Gj^ldenstolpe -^ records it from Doi Par Sakeng and Deignan ^^ from 

 Doi Sutep, 3,800 feet, as hrevicaudata. 



If the above specimens are correctly determined, the range of 

 C. h. venningi would then be the southern Shan States, Burma, 

 Yunnan, and northern Si am.
