there are no detailed descriptions given of the animal I shall be- 
gin by giving a description of it before I discuss the differences 
from subsp. indica. 
The cirri in their armature show two different types. Cirrus 
I and II have somewhat swollen segments armed with transverse 
rows of large spines, and are thus of the same type as the cirri 
of Lepas. In the rami of cirrus III to VI on the other hånd, the

segments are cylindrical with an anterior row of paired spines; 
of these pairs the four are well developed, the basal fifth pair is 
generally very feebly developed; the larger spines are those dis¬ 
tally seated on the segment. 
The rami are always a little unequal in length on the cirrus, 
and also differ in number of segments. In cirrus I the anterior 
ramus has 10, the posterior 14 segments; in cirrus II the corres- 
ponding numbers are 13 and 15. Also in cirrus III to VI the 
numbers of segments of the rami in the same way diffef by two 
in the cirrus; the number of segments in the anterior ramus in- 
creases from 18 in cirrus III to 21 in cirrus VI. — The interval 
between cirrus I and II is only little larger than the other intervals. 
Filamentary appendages are absent. Also real caudal
