A MONOGRAPH OF THE EXISTING CRINOIDS 373 



those of PI, but are less enlarged ; the third and following segments are from 3 to 4 times 

 as long as broad, the distal becoming shorter again with spinous distal ends. P 3 is 5 

 mm. long with 10 segments of which only the first carries a winglike process. This 

 winglike process on the first pinnule segment becomes less and less conspicuous out to 

 the tenth or fifteenth pinnules. The distal pinnules are 7 mm. long with 15 segments 

 of which the first and second are slightly enlarged, from twice as broad as long to as 

 long as broad, and the third and following are from 2 to two and one-half times as 

 long as broad; the 4 terminal segments are shorter and more slender with spinous 

 distal ends. 



In the other specimen the cirri are X, 28-31, about 11 mm. long; a dorsal spine is 

 developed from the twelfth segment onward. The radials are visible interradially. 

 The carination on the elements of the IBr series is very slight and indistinct. The 

 10 arms are 32 mm. in length. Syzygies occur between brachials 3+4, 9+10 and 

 13 + 14, thence distally at intervals of 3 muscular articulations. PI is 5 mm. long with 

 21 segments. P 2 is 6 mm. long with 14+ segments. P 3 is 4.7 mm. long with 13 

 segments. The distal pinnules are 6 mm. long with 13+ segments. 



Parasite. Gisl6n notes that on the first of the two individuals just described there 

 was a parasitic Eulima, probably a Sabinella (or Melanella) similar to, if not identical 

 with, that which I found on an example of Stenometra diadema from the same region 

 (see vol. 1, pt. 2, p. 649).
