(Specimen and details as recorded). 

 The advent of a second example of this species from 

 Sumatra (cf, wing 198 mm.) has caused us to reconsider our de- 

 termination ; and Dr. Hartert who has examined the specimens 

 agrees with us that they are C. optatus. Though very like 

 C. canorus this species is too small to belong to either of the 

 two Asiatic local races, G. c. hakeri and C. c. telephonus. 

 It has nothing to do with G. mlcropterii.^, etc. 

 Page 154, No. 247. We should have stated that the wing lengths of 

 of E. s. scolopacea given by Hartert are those of males only : 

 tiius our males have wings only 1 mm. more than Hartert's 

 maximum. Without doubt, howoever, they are properly det- 

 ermined as E. s. malayana, for in a series of both sexes from 

 Central and Eastern Siam, the wings range from 198 to 

 222 mm. ; and with the exception of three specimens (wings 

 190, 196, 196) a large series of Malay Peninsula males have 

 winofs 197-212. mm.
