proximal pari willi a well-bordered, strong, median tooth visible in 

 side view as a liinh bidontate wing, which, together with the disto- 

 niedian tubert'lc of I Br 1, forms a strong synarthiial prominence. 

 The distal border of I Brax obtnse-angled, with (i — 7 pointed promi- 

 nences. II Br-s: 2, similar to the I Br-s, but with smaller and 

 weaker synarthi-ial tubercles. Arms probably XX |II branches l)roken),

 and (iistally (cf. above). In addition the most pi-oximal Br-s partly with 

 a moilian, dorsal prominence, which develops more distally to a dorsal 

 spine, |)artly with a pair of similar medio-lateral prominences, altei'- 

 nately most developed on the left and on the right. These lateral tu- 

 bercles, situated on both sides of i\nj median dorsal spine, disappear at 

 the 15"' to 20"' Bi--segmeiits and from these only the median dorsal 

 spine I'emains. The distal segments rather strongly pressed together
