has arms 130 mm. long and cirri XIII, 38 — 40, 35 mm. to 40 mm. long; the dorsal spines 
begin on the fifteenth to the seventeenth ; the longest cirrus segments are half again as broad 
as long. A third has arms 115 mm. long and cirri XIV, 34 — 41, about 30 mm. long; the 
dorsal spines begin on the tenth to the thirteenth segments; on several of the cirri the two to 
eight spines following the first three or four have a longitudinally elongate chisel-like apex, or 
are longitudinally paired ; the longest cirrus segments are half again as broad as long ; the colour 
is whitish, becoming purplish toward the end of the cirri and arms. The fourth has the arms 
115 mm. long and the cirri XVII, 41 — 43, 35 mm. to 40 mm. long; the longest cirrus segments 
are half again as broad as long ; spines are developed from the twelfth onward ; the colour is purple. 
In the two specimens from Stat. 164 the arms and cirri are slightly stouter than in the 
preceding, and the cirri are proportionately shorter with a less marked production of the distal 
ends of the segrrtents; in one the arms are about 140 mm. long, and the cirri are XVII, 34, 
27 mm. long; the longest cirrus segments are from half again to twice as broad as long; 
spines are developed from the tenth or eleventh onward, and the earlier spines are double as 
described above; the colour is violet, the cirri yellow becoming violet distally in one example. 
These two closely resemble specimens at hand from Western Australia. The cirri are 
proportionately shorter than in those from Lombok, and the dorsal and ventral profile of the 
individual segments is much le.ss concave so that they appear much smoother, as in the Western 
Australian variety. 
Remarks. — The chief feature of this species is the long stout cirri which taper only 
very slightly if at all distally, and are composed of short appro.ximately equal segments which 
are never so long as broad; as I remember it the type, from Ceram, and those just described 
from Lombok have the cirri much less curved than the others which I have e.xamined; but the 
latter were killed by immersion in fresh water, which may account for their condition; those 
from Lombok have the longest pro.ximal cirrus segments with the most produced distal ends. 
My notes on the type, which I examined during a recent visit to Paris, are as follows : 
"Les cirres sont gros et larges, distalement comprimes; du 12^ ou [3"= article on trouve 
des epines dorsales qui sont assez proeminentes; le premier article est tres court; les suivants 
augmentent progressivement jusqu'aux 8^ ou 9^, qui atteignent en longueur une moitie de la 
largeur; tous les articles des cirres sont a peu pres egaux en grandeur. II y a dix bras, qui 
sont robustes; les plaques radiales sont cachees; I'article IBr,, est tres court, a peu pres entiere- 
ment uni avec les voisins; I'article IBr a.xillaire est presque triangulaire, et atteint une largeur 
de deux fois la longueur, ils ne se touchent pas tout a fait lateralement; les tubercules synarthriaux 
ne sont que legerement developpes; les articles brachiaux sont extremement courts, un peu 
imbriques; les pinnules sont comme dans Y Amphivietra inilberti decrite par Carpenter (c'est 
a dire X jiniphimetra molleri). La couleur est d'un noir brunatre".
