96 K. IMITSUKURI : STUDIES ON 



All these facts have puzzled me considerably, and the best 

 and most satisfactory solution seems to be the following assumption: 

 — There is a very extensive species which by reason of the law 

 of priority ought to be called H. lubrica Ludwig. This has 

 produced or is in the process of producing local varieties with 

 many intermediate forms. As belonging to the species indicated 

 I consider the following varieties : — 



(1) var. moehii (Ludwig) 

 Literature given aljove. 



Locality : — Hongkong (Ludwig '83) ; Mauritius (Théel '86). 



(2) var. glaherrima (Selenka).

It is acknowledged by all that H. erinaceus Semper with its variety 

 jjygmœa is identical with H. glaherrima. I append here its literature and 

 distribution : —
