A MONOGRAPH OF THE EXISTING CRINOIDS 235 



6*. IIIBr series absent, or if present all or mostly 2. 



c 1 . Longest proximal cirrus segments about as long as broad sometimes slightly broader than 



long or slightly longer than broad. 



d 1 . Longest cirri, in fully grown individuals, with more than 30 segments. 

 e 1 . Larger, with 10-19 arms 100-150 mm. long. 

 f 1 . Outer cirrus segments with small carinate dorsal spines which develop gradually; 



proximal portion of the arms with a distinctly serrate profile. 



1 . Profile of the proximal portion of the arms strongly and roundedly serrate, the ser- 

 rations pointing distally; carination of the basal segments of the earlier pinnules 

 very slight, almost vestigial; 19 arms 145 mm. long (Amboina; about 2 



meters) sarae (p. 318) 



g 2 . Profile of the proximal portion of the arms angularly serrate, the serrations pointing 

 proximally; dorsal profile of arms beyond the proximal third smooth; carination 

 of the basal segments of the earlier pinnules conspicuous, though not exaggerated; 



10-16 arms 100-150 mm. long (Philippines; 38-44 meters) parilis (p. 319) 



/*. Outer cirrus segments with long and prominent dorsal spines, which begin abruptly; 

 elements of the division series and earlier brachials with the dorsal surface unmodi- 

 fied (Bagamoyo and Zanzibar to Waxin and from Kurrachi to Persian Gulf; 0-88 



[?89] meters) africana (p. 325) 



e 2 . Small and delicate, with 12-13 arms 70-85 mm. long (southern Japan). schlegelii (p. 329) 

 d 2 . Longest cirri with never more than 31, and usually much less than 30 segments; distal or 

 proximal ends of the earlier brachials produced (Ceylon and Bay of Bengal to Philip- 

 pines; 0-44 [?84] meters) bengalensis (p. 321) 



c 2 . All the cirrus segments much broader than long, the longest proximal segments being one- 

 third to one-half again as broad as long. 

 d 1 . Cirri very stout and strongly curved, with 29-30 segments; 10-13 arms 170-180 mm. 



long (Maldive Islands) flora (p. 333) 



d 2 . Cirri less stout and less strongly curved, with usually about 30 segments; 19-39 (most 

 commonly about 30) arms 75-85 mm. long (Delagoa Bay) delagoae (p. 334)
