70 
slightly longer segments distally which bear a few conspicuous spines on their overlapping 
distal ends; the distal pinnules are exceedingly slender, 7 mm. long with 17 segments of which 
the third and following are greatly elongated; the third bears a narrow carination. 
A second specimen is similar to the one described; the third, with the same arm length 
and number of cirri, has the production of the distal edges of the lower brachials and of the 
proximal pinnule segments more pronounced. 
The 55 specimens from Stat. 294 vary in arm length from 27 mm. to 65 mm., most 
of them being between 55 mm. and 65 mm. Even in the smallest the carination of the earlier 
pinnule segments is nearly as strong as in the adults, though more rounded and not truncate 
nor dentate distally ; but only the median swollen portion of the eversion of the borders of the 
brachials is developed. In these specimens the carination of the first pinnule segment is often 
much higher than the transverse diameter of the segment, fan-shaped, and with a dentate crest. 
A specimen from "Albatross" Stat. 5355, Philippine Islands, 44 fathoms (Cat. X" 36009 
U. S. Xat. Mus.), appears to belong to this species.

One of the specimens may be described as follows: 
Centrodorsal discoidal, the cirrus sockets arranged in two rows; the bare dorsal pole is 
2.5 mm. in diameter. 
The cirri are XXI, 18, 12 mm. long, comparatively slender; the segments increase in 
length to the fourth-sixth, which are about twice as long as the proximal diameter; the distal 
seven or eight are about as long as broad; the longer segments are centrally constricted with 
widely flaring distal ends. 
The distal edge of the radials and the proximal border of the IBr^ are slightly thickened 
and turned outward; there is a slight tubercle in the centre of the latter; the distal edge of 
the IBr series is everted, the middle fourth thickened into a transversely elongate tubercle; the 
central half of the distal border of the proximal discoidal brachials is everted and spinous ; the 
distal edge of the following brachials is slightly produced and finely spinous; the lateral borders 
of the IBr series are finely dentate. 
Pc is 5 mm. long, composed of 12 segments; Pj is 7.5 mm. long with 15 segments; 
Po is 12 mm. long with 16 — 18 segments, at first short, becoming about as long as broad on 
the fourth, twice as long as broad on the eighth or ninth, and slightly longer terminally; the pinnule 
is only moderately stout; the segments overlap slightly along the prismatic crest, where there is 
a slight development of spines on their distal ends; in profile the prismatic crest is slightly notched. 
The other specimen is similar; it has arms 50 mm. long. 
It is quite possible that this form should be regarded not as a distinct species, but as 
a strongly marked variety of E. indivisus, bearing the same relation to the latter that Cotylo- 
metra gracilicirra does to Cotylometra gracilicirra ornata.
