The color in alcohol is black tinged with purplish, the cirri somewhat lighter and 

 more reddish. 



Notes. In the specimen from Cambodia as described by Gisle'n the centrodorsal 

 is subconical, 6.5 mm. in diameter, with a small concave bare dorsal pole. The cirrus 

 sockets are arranged in about four rows. 



The cirri are XLIV, 41-51, from 28 to 40 mm. long. The longest earlier segments 

 are from one-third again to twice as long as broad, and the distal segments are twice as 

 broad as long. On about the twelfth segment a transverse ridge appears. Especially 

 when observed from the distal end of the cirrus this ridge is seen to be crowned with 

 small tubercles. At first the number of these tubercles is about 4, later rising to 7; on 

 the distal segments there is a decrease to 5, 3, and finally to 2. There are 3 tubercles 

 on the 3 to 6 segments before the antepenultimate, which last bears 2 spines only. 

 The opposing spine is simple. The terminal claw is short and strongly curved. 



The radials are visible as narrow bands. The IB^ are three tunes as broad as 

 long, smooth, well rounded dorsally, and diverging from their neighbors. The IBr 2 

 (axillaries) are pentagonal, one-third again as broad as long. There is a well-circum- 

 scribed and prominent synarthrial tubercle on the articulation between the elements of 

 the IBr series. Of the seven IIBr series present six are 4(3+4) and one is 2. The 

 IIBr] is twice as broad as long. Of the thirteen IIIBr series present, twelve are 2, 

 and one (abnormal) is 4(3+4). Of the eight IVBr series present, seven are 4(3+4) 

 and one is 2. There is a synarthrial tubercle or the articulation between the two first 

 elements of the IIBr series similar to that on the IBr series but smaller, and there are 

 insignificant tubercles at the following synarthrial articulations. 



PPP seems always to be absent. On the inner arms (P,), P a , P 2 , P b , and even P 3 

 may be absent. P D is short, smooth, and curved, with 15 segments. 



P! is 23 mm. long with 20 segments of which the first is twice as broad as long, the 

 second is half again as broad as long, the third is half again as long as broad, and those 

 following are about twice as long as broad. This pinnule becomes flagellate distally. 

 From the seventh onward the segments have everted and spinous distal ends. 



P 2 is 19 mm. long with about 18 segments. 



The pinnules following decrease in length. P 7 , is 5 mm. long with 13 segments, 

 and is smooth and slender. 



The color is brownish violet, the smooth disk brown. 



In the specimen from Pulo Condor the cirri are XXXVI, 49-51. There are not 

 more than 5 eminences on the transverse ridge. 



Of the ten IIBr series, eight are 4(3+4) and two are 2. Of the eleven IIIBr 

 series, ten are 2 and one is 4(3+4). Of the eight IVBr series, five are 4(3+4) and 

 three are 2. The remaining division series have been lost. There were probably 

 about 50 arms. 



The pinnulation is defective, as in the preceding specimen.
