armature in the specimens investigated by me (cf. for other details pp. 702 — 706 below): Somewhat 

 distally of the middle this bristle has two rows of proximally pointing spines along about 

 a quarter of its length. The distal spines in each of these rows are situated close together; 

 these spines are situated in pairs in the two rows. From the eighth or the tenth pair, counting 

 distally-proximaUy, the two rows approach each other and the spines push alternately in between 

 each other, so that a single, though not a quite straight, row is formed; at the same time the 

 distance between the spines increases, some of these being often even rather sparsely situated 

 (about the same as in pi. 6, fig. 5, G. W. MCLLER, 1894). In profile I saw about 20 — 25 spines
