The spccinieus from tliis locality (lilfcr from the type only 

 in having tlic transverse lirte red. The speeimens in tlie 

 Cuming collection appear to have been over-cleaned with 

 acid, and consequently this red lineation, of which, however, 

 I can still find traces, may have been destroyed. The locality 

 given by llccve, '' West Colonil)ia,'' I regard as a mistake, 

 for Mr. (r. H. Sowcrljy informs me that he knows it for 

 a certainty as a Hong Kong species.
