minor. The last two forms—hawarahiba and minor—are much darker than the new form as well as wsswriensis. 
Clark (2, c.) mentioned that の. s. wssurianus (error) [wsseriensis| Hartert was very common on Matsushima, July 
28,1906, but it probably belongs to the new form. 
The subspecific name is given in honour of Mr. Austin H. Clark.
