( >n the specimen from Stat. 40 only a single undeveloped cirrus with 49 segments remains.

The largest specimen from Stat. 80 has the cirri XV, 36 — 39, iS mm. to 21 mm. long; 

 the cirri are slightly more slender than in the type series, with the long proximal segments 

 slightly more elongate; the dorsal pole of the centrodorsal is papillose; Pj is 5.5 mm. long 

 with 13 segments; 1\ is 9.5 mm. long with 14 segments; I' is 8.5 mm. long with 14 segments, 

 similar to I' . 1' is 6.5 mm. long with ii segments, similar to P 3 ; P 8 is 7 mm. long. The 

 elongated proximal pinnules are relatively ^horter and more recumbent than in the typical form. 



< )f the other specimens two have arms 40 mm. and 45 mm. long respectively ; the third 

 has arms 15 mm. long and cirri IX, 12, 3 mm. long, resembling the cirri of the species of 

 /'roiuttra, the segmen tly about as long as broad. On most of the arms P a and 



\\ have not as yet appeai 



The example from Stat. 310 has the cirri with 39 — 48 segments (one of each), 25111111. 

 to 35 mm. long; the longest cirrus segments are slightly longer than broad; P ï is 8 mm. long 

 with 19 segments; 1', is 12.5 mm. long with iS segments; 1' is 10.5 mm. long with 14 — 17 

 segments; P, is 9 mm. long with 15 segments; the lower pinnules are rather less stiffened 

 than usual in this species, and are slightly recurved ; the spines on the distal ends of the 

 pinnule segments are shorter and less prominent than is commonly the case; there are no 

 synarthrial tubercles. The size is the same as that of Ipecimens of this species at hand from 

 tin- Andaman Islands.
