ally. The IBrj (axillaries) are triangular, three times as broad as long. The 10 

 arms are 105 mm. long. The first brachials are 2.7 mm. long, twice as long exteriorly 

 as interiorly, interiorly united for one-third of their length. The second brachials 

 are twice as long exteriorly as interiorly. The brachials are distally somewhat over- 

 lappmg, giving the distal portions of the arm a somewhat serrate profile. There are 

 15 brachials for each 10 mm. of arm length, or 12-13 if the syzygial pairs are counted 

 as units. The proxunal portion of the arms is smooth, and a little flattened. The 

 elements of the IBr series have a sharp lateral edge, but never a mediodorsal carin- 

 ation. Syzygies occur between brachials 3+4, 8+9 (or 9 + 10), and 16 + 17, and 

 distally at intervals of from 5 to 9 muscular articulations. Pi is 12.5 nmi. long with 

 24-25 segments of which the second-fourth have a slight keel on the side toward the 

 arm tip. P2 is similar to Pj. P3 is 12 mm. long with 25 segments. P5 is 11 mm. 

 long with 21 segments. Pg is 8 mm. long with 23 segments. P, to Pj are without 

 ambulacral furrows, larger and stouter than the other pinnules, and carry gonads. 

 But the difference is not so marked as it is m T. ajra macrodiscus. The distal pinnules 

 are 14 mm. long with about 30 segments of which the first two or three are short 

 and the remainder are from half again to twice as long as broad. The disk is 13 mm. 

 in diameter. The color is red-violet.
