with rings (mostly unpaired), and a 60 mm 
ringed portion where the segmentation is not 
apparent. This breaking down of the segmenta- 
tion is similar to that of S. sumatrense, but the 
rings are more like those of S. silone. The other 
two pieces are segmented, one being rather dark 
chestnut brown and more rigid. 
The diameter of the two lighter tubes is 
0.16-0.17 mm and the darker, sturdier one 
measures 0.18-0.19 mm across. The rings are 
very thin toward the ends of the tube (about 
9 /*), gradually becoming about 18-19 /x, and 
then, where the rings double, they measure 
about 36-40 [x long, or about the diameter 
of the tube. There are from 16-24 rings per \ 
segment.
