bluish hkick spots. Vontrnm sometimes lighter. 



Remarks : — This species is confmecl to the sonthern half of 

 Japan. I have specimens not only from the Ogasawara Is. as 

 reported by Brandt, but also from the Okinawa Is. In Japan 

 proper there is a specimen from Satsuma. It is somewhat 

 remarkable that no specimen of this species has yet been found 

 in Misaki, seeing that v. Marenzeller reports it as from Eno- 

 shima close by. 



One Ogasawara specimen, not much contracted, agrees well 

 with the description given by authors in color and markings, i.e., 

 in being reddish brown with two rows of large, irregular, black 

 spots, 7 — S in one row. The contracted specimens often acquire 

 a peculiar appearance which serves for preliminary specific deter- 

 mination. The dorsum (in alcohol) acquires a purplish brown 

 tinge with papillae standing out as spots of a reddish brown. 

 Moreover, the surface 

 is marked out into 

 irregular polygonal 

 areas. 



Tables (textfig. Ki 

 /; — e) are rather 

 sparse. The disk usu- 

 ally consists of only 

 an aiuiulus or at the 

 most, has only a small 

 additional opening and 

 ajipcjirs like a rather 

 square disk (e). The 

 spire arises directly 

 from the annulus and ends above in a crown with four groups of 



m.
