and is naked and somewhat incised. Sacculi are closely set along the pinnule ambu- 

 lacra but are rather farther apart on the arms. The color in alcohol is white with 

 deep purple bands on the arms, especially at the syzygies. 



I examined this specimen at the Leyden Museum in 1910. It fits closely the 

 description of the form I called pulchella. The projection of the distal ends of the 

 lower pinnule segments is not greatly accentuated. The purple bands on the arms 

 are very narrow. 



The specimen from Siboga station 164 has the arms 50 mm. long. P 2 is greatly 

 enlarged with strongly marked processes. P 3 is small, like P 4 . 



All five of the specimens recorded by Keichensperger from Nuhu Tawun, Little 

 Kei, agree almost completely with Carpenter's description of the type specimen from 

 Andai, New Guinea. The smallest has an arm length of only about 43 mm. The 

 cirri are XI, 15; the middle segments appear somewhat longer in relation to the 

 width than in the larger specimens. The longest cirrus is 6 mm. long. P 2 is com- 

 posed of 12 or 13 segments and shows prominently the distal serrate produced ends. 

 The arm length of the largest specimens reaches 105 mm. (see page 234). These have 

 the cirri XII-XIV, 18-20, from 8 to 9 mm. long. The cirri are stout with broad 

 segments which on the dorsal side bear a prominent keel with evident small teeth. 

 The serration of the proximal pinnules is sometimes very strongly developed and 

 sometimes only feebly developed (pulchella). In the middle arm region the syzygies 

 are fairly regularly spaced, mostly with an intersyzygial interval of 6-8 muscular 

 articulations. A large individual is wholly dark brown-violet. The others have 

 more or less broad light violet bands and spots. The smallest is dorsally light reddish. 



The specimen from Siboga station 258 has rather slender cirri with 16-17 segments 

 which beyond the eighth are about as long as broad. P 2 is much enlarged, much 

 larger than the other pinnules, 7 mm. long, with 17 segments most of which are about 

 as long as broad; the lateral processes are small and narrow (anterodistally) and 

 are armed with fine spines. P a is absent on all the arms of three postradial series, 

 six arms in all. This individual approaches the African occidentalis. 



The specimen from the Danish Expedition to the Kei Islands station 54 has the 

 arms 40 mm. long. P 2 is slender with the processes on the distal angles of the segments 

 unusually long. 



The specimen from the Danish Expedition to the Kei Islands station 43 is small 

 and slender. 



The specimen from Banda has the arms 70 mm. long. P 2 is very stout, sharply 

 prismatic, with the distal angles of the segments prominently spinous. The color 

 is deep purple, the cirri flesh color. 



The 10 specimens from the Danish Expedition to the Kei Islands station 75 

 are all small, as is that from station 74. 



The specimen from the Danish Expedition to the Kei Islands station 104 is very 

 small. 



One of the specimens from Singapore was described as a new species under the 

 name of Ol'lgometra pulchella in the following terms: 



The centrodorsal is discoidal with the large polar area circular, flat, and unmarked. 

 The cirrus sockets are arranged in a single marginal row. The cirri are XIV, 16-23 

 (usually about 18), 7 mm. long, and comparatively slender. The first segment is
