laterally, therefore appearing broad in lateral view. The transition 

 and following segments have the distal dorsal edge everted, forming 

 a minute sharp tubercle in lateral view, at first subterminal but 

 becoming median on the antepenultimate; the opposing spine is rep- 

 resented by a minute median tubercle only slightly larger than the 

 tubercle on the preceding segment; the terminal claw is slightly 

 longer than the penultimate segment, rather stout, and strongly 

 curved, more so basaUy than distally. 



The radials are even with the edge of the centrodorsal in the 

 median line, but extend up interradially and entirely separate the 

 bases of the IBr^; the IBr series are widely separated, their sides 

 making nearly a right angle with the sides of the adjacent IBr series. 

 The union of the elements of the IBr series is very close, appearing 

 almost like a syzygy in external view. 



The 10 slender arms are from 30 to 39 mm. long; the brachials, 

 which are proportionately long, have strongly produced and over- 

 lapping spinous distal ends. 



The mouth is marginal and the anal tube subcentral; the anal 

 area is completely covered with smaU thin calcareous plates. 



Locality. — Eig Tor, Gulf of Suez, Red Sea. Eight specimens, col- 

 lected by Dr. Robert Hartmeyer. 



Remarks. — The type material consists of eight specimens. That 

 which was selected as the type-specimen has the arms 30 mm. long; 

 the cirri are IX, 11-13, 5 to 6 mm. long; syzygies occur between the 

 third and fourth brachials, again between the tenth and eleventh or 

 eleventh and twelfth (usually the latter) and fourteenth and fif- 

 teenth to seventeenth and eighteenth, and distally at intervals of 

 three (more rarely two) oblique muscular articulations. Another 

 specimen has the arms 33 mm. long, and the cirri VIII, 10, 4.5 mm. 

 long. A third has the arms 39 mm. long, and the cirri XIV, 11-12 

 (usually the latter) 5 mm. long. A fourth has the cirri IX, 12-13. 

 The remaining four specimens are similar to these. 



The type-specimen is in the Berlin Museum.

The centrodorsal is very large and massive, thick-discoidal, with a 

 very slightly convex polar area 7 mm. in diameter; the cirrus sockets 

 are arranged in a single crowded, slightly irregular marginal row. 



The cirri are XX-XXII, 32-34, 15 mm. long, rather slender, 

 decreasing slightly in diameter from the base to about the eighth 

 segment, then remaining the same to near the end, the terminal
