1. Eig Tor, Gulf of Suez; Dr. R. Hartmeyer; Cat. No. 5601.— One 

 specimen. 



Centrodorsal thick discoidal witn a single marginal row of cirrus 

 sockets. 



Cirri XVI, 18 (only one remaining), 13 mm. long; the outer cirrus 

 segments are about half again as broad as long. 



The arms are about 80 mm. long; the carination on the brachials 

 is moderately developed. 



The lower pinnules are very stiff, especially P2, P3 and P4; P^ is 7 

 mm. lo;ig with 16 segments; Pg is 7 mm. long with 14 segments, 

 stouter basally than Pi; P3 is 6.5 mm. long with 16 segments; P^ is 6 

 mm. long with 16 segments; Pg, P3 and P^ sometimes have spinelike 

 tips resembling those of the proximal pinnules of the species of 

 Stephanometra, and are very stiff; P^ is also more or less stiffened; 

 Pg is 6.5 mm. long with 20 segments, slender, delicate, and distally 

 flagellate, not stiffened like the preceding ; Pg resembles P5 ; the distal 

 pinnules are very slender. 



2. Ras-el-Millan, Gulf of Suez; Dr. R. Hartmeyer; Cat. No. 

 5603. — One specunen, smaller than the preceding; the arms are about 

 50 mm. long; the cirri are XXIII, 16-17, 13 mm. long. Many of the 

 cirri are small, from 9 mm. long with 14 segments upward; these 

 all appear to be juvenile cirri which will be lost before maturity is 

 reached. The lower pinnules have the same sharp tips as those in 

 the preceding example. 



3. Aden; Prof. J. Miiller; Cat. No. 1050. — One rather small speci- 

 men. 



This new species is nearest to T. indica from Ceylon, from which 

 it differs in having fewer cirri composed of fewer segments, and less
