A MONOGRAPH OF THE EXISTING CRINOIDS 191 



in length and becoming about as long as broad on the fourteenth, and twice as long as 

 broad on the small terminal segments. The segments in the middle half of the pinnule 

 have the distal dorsal edge slightly swollen and prominent. P P is 26 mm. long, with 

 33 segments, and is similar in every way to P D . P x is 18 mm. long, with 25 segments, 

 similar to the preceding pinnules but proportionately smaller. The cirri, centrodorsal, 

 and division series are pinkish flesh color, the arms are slaty, and the proximal pinnules 

 and the outer portion of the middle and outer pinnules are pinkish. 



Of the specimens from Port Galera, Mindoro, one (original No. 202) has 58 arms 

 140 mm. long; another (original No. 224) has 51 arms; a third (original No. 150) has 

 40 arms and 35-38 cirrus segments; in this individual the proximal pinnules are very 

 large and stout, long, with 23-28 segments, and without a flagellate tip but tapering 

 gradually distally; a fourth specimen has 33 arms; this last in life had the bases of the 

 arms whitish or light straw color, the arms transversely barred with brown, the pin- 

 nules barred whitish and brown, and the anal tube straw color spotted with light brown. 

 In its present dry condition it is a uniform purplish brown. 



In the specimen from Pulo Condor, Cochinchina, as described by Gislen, the 

 arms are broken and the cirri have been lost. The centrodorsal bears sockets for 

 XXXIV cirri. The IIBr series are 4(3+4) and the IIIBr series 2, the latter usually 

 developed internally. There are 28+ arms. P P is about 15 mm. long, with 19 seg- 

 ments, very stout, tapering distally, composed of smooth and short segments of which 

 the longest are scarcely as long as broad ; there is a slight constriction at the articula- 

 tions, which makes the pinnule appear somewhat knobby. The pinnules are mostly 

 broken at the tips. The color is violet. Gislen says that because of the rather small 

 size and few arms this must be considered as a young individual. 



The specimen from Ulugan Bay, Palawan, is a magnificent example of the species 

 with 42 arms 184 mm. long and the cirri XXXIII, 29-35, 30 mm. long. The color in 

 alcohol is a uniform deep violet. 



One of the specimens from Bantayan Reef, Cebu, has 46 arms. In life the center 

 of the dorsal surface was dull ochre, and the arms were crimson shading to rich 

 chocolate at the tips. In the present dried condition it is a uniform brown. 



The single broken specimen from Isabela, Basilan, has 40 arms. The cirri are 32 

 mm. long and are composed of 32 segments of which the terminal 15 have a minute 

 submedian tubercle, which increases in size distally. The distal edges of the segments 

 of the proximal pinnules, which are large and very stout, are everted but not spinous. 

 The IIBr series are 4 (3+4). The IIIBr series are 4 (3+4) externally and 2 internally, 

 or all 4 (3+4). The following division series, when present, are 4 (3+4). 



In the fragmentary specimen from Ekalin, St. Matthias Island, the cirri and lower 

 pinnules are very slightly stouter than they are in the specimen just preceding, and 

 the segments of the lower pinnules have less prominent distal ends. 



The three fine specimens from Pitilu, Admiralty Islands, have 36, 44, and 47 arms 

 130 mm. long. 



The specimen from Ternate has 45 arms. 



The specimen from the Danish Expedition to the Kei Islands station 11 has about 

 40 arms 140 mm. long. The cirri are XXVII, 39-40, 35 mm. long. P D has 42 seg- 

 ments, and Pi has 42 segments and is 25 mm. long.
