are furnished on their outer margin with a row of peculiar tubercular 

 bodies. Each ramus of furca is provided with a row of roddikc 

 processes, which row embraces the furca obliquely from the outside 

 at the end of the proximal third of its length (fig. 29). The 

 rods arc longest in the middle of the row and become shorter by 

 degrees toward its both ends. Of this peculiar structure nothing is 

 given in Brady's description (/. c.) of the type species, but it constitutes 

 a very characteristic feature of the form which is here made into a 

 new subspecies. 



This cyclops is found in the vicinity of Sapporo, but seems to 

 be very rare.
