bluish black spots. Ventrum sometimes lighter. 



BemarJxS : — This species is confined to the southern 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. Maeenzeller reports it as from Eno- 

 shima close by. 



One Ogasawara specimen, not much contracted, agi-ees well 

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

 in being reddish brown with tw^o row^s of large, irregular, black 

 spots, 7 — 8 in one row. The contracted specimens often acquire 

 a peculiar appearance w^iich serves for preliminary specific deter- 

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

 tinge w^th papillae standing out as spots of a reddish browm. 

 Moreover, the surface 

 is marked out into 

 irregular polygonal 

 areas. 



Tables (textfig. 16 

 b — e) are rather 

 sparse. The disk usu- 

 ally consists of only 

 an annulus or at the 

 most, has only a small 

 additional opening and 

 appears like a rather 

 square disk (e). The 

 spire arises directly 

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