IV ■ i nun. long, moderate^ stout, strongly prismatic, evenly tapering to the 

 tip, the distal bonier of the Begmenta sharply, though narrowly, carinate, composed 

 ,,f n aegmenta. I\ aimilar to IV. 4.5 mm. long, with 12 segments. P. is 11 mm. 

 long, with 17 Begmenta, \cn Blender like the succeeding pinnules, though very stiff. 

 The Brat two Begmenta ere Blightly broader than long, the third and fourth half again 

 aa Long aa broad, and the following gradually increase in length, becoming distally 

 three or four times aa long aa broad; distal edges of the third and following segments 

 are produced and spinous. The pinnule resembles the lower pinnules in certain of 

 the more slender Bpeeiea of Colobometra. P, is similar to P., 11 mm. long, with 17 

 Begmenta. 1',, is similar to P„ 8 mm. long, with 18 segments. P 3 is 8 mm. long, 

 with L8 Begmenta, proportionately slenderer than P, and with much shorter segments, 

 which become aa long as broad on the third and twice as long as broad basally on the 

 tenth or eleventh. P, and 1\ are 7.5 mm. long, with 18 segments, and resemble the 

 preceding pinnules; the distal pinnules arc 12 nun. long, with 20-24 segments, which, 

 beyond the fifth, arc twice, and distally three times, as long as broad, with very 

 finely Bpinoua distal ends. 



The deposits along the amhulacra in this species are essentially the same as in

Nates. The preceding description was drawn up from the type specimen from 

 Slboga station 310. 



The anus in the six specimens from the Danish Expedition to the Kei Islands 

 station 54 are up to 55 nun. in length. 



The specimen from off Jolo in about 46 meters may be thus described: The 

 centn dorsal is thin disci idal with a broad flat dorsal pole; the cirrus sockets are 

 arranged in a single regular marginal row. The cirri are XV, 17, moderately stout 

 and strongly curved. The Oral two segments are more than twice as broad as long, 

 and those following are all about as long as broad, the fourth being sometimes, but 

 imt always, Blightly longer than broad. The third and fourth segments are rather 

 Btrongly constricted centrally, and the two following have somewhat flaring distal 

 ends. The opposing spine is prominent, conical, with the apex median, and rises to 

 a height equal to half the width of the penultimate segment. The terminal claw is 

 slightly longer than the penultimate segment, rather stout, and strongly and usually 

 evenly curved. The radials have a slightly and very finely roughened distal border. 

 The brachial structure resembles that of E. indinsus. The distal edges of the bra- 

 ohiala arc very finely spinous but are not produced. 



P c is about i\ nun. long and is composed of 15 segments; it tapers evenly from a 

 [airlj broad base to the tip. The first two segments are much broader than long, 

 the fourth is about as long as broad, and the remainder are about half again as long 

 as broad. The pinnule is not obviously prismatic, the dorsal ridge being so broadly 

 rounded as acarcerj to be evident. Each of the first five segments bears a conspicuous 

 sharp carinate process wiili the creel straight and parallel to the longitudinal axis of 

 the pinnule. On the first segment this crest occurs only in the distal half, but it 

 occupies the entire aide of the other segments. It is highest on the second-fourth 



Lenta, lower on the fifth, and very low on the sixth. P, is very slightly longer 

 than IV and also stouter it h composed of 14 segments, which become about as 

 long aa broad on the fourth and half again as long as broad distally. The first four
