 p. 42 (1). 



I. Suez; 10 fathoms.- — One broken specimen; the cirri are XXV, 

 14-16 (usually 15-16), 10 mm. to 13 mm. long, comparatively stout; 

 the first segment is short, the second about as long as broad, the fourth 

 or fifth the longest, about two and one-half times as long as the me- 

 dian diameter ; the following segments decrease slowly in length so 

 that the antepenultimate is about one-third longer than broad. The 

 longer proximal segments are constricted centrally and have enlarged 

 distal ends ; there are no dorsal processes ; the opposing spine is 

 prominent, terminal, and directed obliquely forward ; the cirri as a 

 whole are rather strongly compressed laterally. 



The ten arms are apparently about 40 mm. long, and resemble 

 those of /. nana. 



Pj is short, evenly tapering, about 5 mm. long, with eight seg- 

 ments which become twice as long as broad distally ; P 2 is consider- 

 ably larger and much longer, but evenly tapering and very slender 

 distally, 9.5 mm. long with twelve segments which become much
