PART 5 A MONOGRAPH OF THE EXISTING CRINOIDS 279 



about as long as, or ratlior longer than, broad, becoming less and less obliquely wedge- 

 shaped distally, and finally oblong and elongate. All the brachials are perfectly 

 smooth, with no ornamentation of any kind. 



Syzygies occur between brachials 3+4, 9+10, and 14+15, and distally at intervals 

 of 2 muscular articulations. 



Pi is 9 mm. long, very flexible and slender, composed of 35 to 40 short segments 

 most of which are about as long as broad with all the angles cut away and hence 

 appearing rounded, those in the terminal third becoming slightly elongated; the 

 articulations are enlarged, and the whole pinnule suggests a string of small beads. 

 Pa is 5 mm. long with 12 to 15 segments, of which the first two arc about as long as 

 broad and the fourth and following rapidly become elongated and the distal very 

 slender; the fifth, sixth and seventh segments bear a large rounded gonad. The 

 following pinnules to Pg are similar, but the gonad gradually moves nearer the base of 

 the pinnule, on Pg extending from the third to the sixth segment. The distal pinnules 

 are 12 mm. long with 20 segments of which the first is very short, almost bandlike, the 

 second is almost triangular, the third is about half again as long as broad, the foiu-th 

 is about t\vice as long as broad, and the remainder become progressively elongated. 



Color. — The color in alcohol is yellowish white with a large black spot on either 

 side of each syzygial pair; the inner half of the articular faces of the syzygies is also 

 black. 



Locality. — Albatross station 2134; off Santiago de Cuba (lat. 19°56'06" X., long. 

 75°47'32" W.); 464 meters; February 27, 1884 [A. H. Clark, 1918] (1, U.S.X.M.,
