Sp. 14 (St. 56) Interarticular pores to the 6*'' internode. 5 inter- 

 nodals without cirri. Full number of internodals in the 3'' internode. 



Cirri 34 (VIP" cirrus-provided node); 34 (IX) 22 mm., 32 (XII). 



B — s 1 X 1,3 mm. R — s 1X3 mm. forming an angle with the 

 B— s. The arms broken. P^ (to the right on I Br 2 in 5 cases) 12; 

 9 mm. Disk 7 mm. Anal cone 5 mm. 



Sj). 15 (St. 56) 3 nodal joints without cirri. Full number of inter- 

 nodals in the 3'' internode. Interarticular pores to the 6^'' internode. 

 The distal internodes often have one of the middle internodal joints 

 provided with tubercles; this is an indication of the formation of a 

 nodal joint. One such middle node is perfectly developed between the 2'' 

 and 3** internodes, counted from the distal end of the stem. (Here there- 

 fore only 4 and 3 internodal joints appear.) The distal stem-joints al- 

 most perfectly round. 



Cirri 34 (IV) 22 mm.. 32 (VII), 30 (XI), 30 (XIII) 17 mm., 28 (XV). 

 The cirrus-sockets of the distal nodals do not quite reach to the proximal 

 border of the joint. Nevertheless, the usual type is to be found 

 already at the IX"' node, where the joints also begin to become some- 

 what pentagonal. 



The arms broken. P^ (to the right on I Br 2 in 3 cases) 12; 

 7 mm. Disk 6 mm. Anal cone 5 mm. 



6^). 16 (St. 56) 8 nodals without cirri. Full number of inter- 

 nodals in the fii'st internode. Interarticular pores to the 2'' internode. 

 The number of internodals when counted proximo-distally runs as fol-
