hair-like black shaft-lines ; throat rusty buff, with black

POMATORHINUS TICKELLI HAINANUS, n. Subsp. 



Differs from P. tickelli tickelli in its smaller size, less 

 rufous and more olive brown upper surface and flanks, 

 shorter and more blackish bill. Wing 97-101, tail 95-97, 

 bill from base 35-41, metatarsus 37-38 mm. Colour of 

 bill dark mouse-grey, not pale brownish as in P. t. tickelli. 



Represents P. t. tickelli of Tenasserim in Hainan, whence 

 I have received a series of 14 males and females collected at 

 No-tai, Laimui-Mon, and Mt. Wuchi. (Type d , No. 90 a, 

 No-tai, 30.ix.1902, Katsumata Coll.) 



ClSSA KATSUMATiE, n. Sp. 



In general appearance like C, chinensis, but differs strik- 

 ingly in the colour of the inner secondaries ; these are 

 reddish chestnut, almost blood-red, with wide greenish-blue 

 (in fresh plumage probably quite green) tips, much wider 

 and less pale than in C. chinensis and without even an in- 

 dication of the black snbterminal bars which are so con- 

 spicuous in C. chinensis. The tail is shorter. Wing 138, 

 tail (apparently full-grown) 138, tarsus 46 mm. 



This interesting new form will probably prove to be 

 a subspecies of Cissa chinensis, but so far I have only a 

 single female, No. 183 a, Mt. Wuchi, Hainan, 21.iii.1903, 

 Katsumata Cull. 



Named in honour of its discoverer.
