A MONOGRAPH OF THE EXISTING CRINOIDS 187 



5 IIBr series are 4 (3+4). The brachials are very short with their edges almost 

 parallel. In all of the specimens from Banda the distal edges of the brachials are 

 rather strongly everted and abundantly spinous. 



The Challenger specimens from Banda have not more than 18 cirrus segments. 

 In one of them the carination of the basal segments of the lower pinnules seems to be 

 almost entirely absent, although it is present in the others. 



Of the 2 specimens from Siboga station 240, at Banda, the larger has about 26 

 arms which are about 105 mm. long; 3 of the IIBr series are 2; the IIIBr series are 



3 (2 + 3). The cirri are XV, 24-26, from 22 to 25 mm. in length. 



The individuals from Siboga station 162 are small; 1 has 14 arms with all the 

 IIBr series 4 (3+4), and the other has 13 arms with 1 of the IIBr series 2 and the 

 2 others 4 (3+4). 



The specimen from Siboga station 250 has 14 arms 50 mm. long and the cirri 

 XIII, 14 mm. long. 



Of the specimens from the Danish Expedition to the Kei Islands, that from 

 station 11 has 19 arms 120 mm. in length; the 9 IIBr series are all 4 (3 + 4). 



One of the specimens from station 14 has 25 arms; there are 9 IIBr series, all 



4 (3 + 4) ; of the 6 IIIBr series 4 are 3 (2 + 3) and 2 are 2 (1 + 2). Another has 21 arms; 

 of the 10 IIBr series 8 are 4 (3 + 4) and 2 are 2; there is a single IIIBr 3 (2 + 3) series, 

 internally developed. The third specimen has 17 arms 120 mm. long; there are 

 7 IIBr 4 (3 + 4) series. 



The example from station 15 has 21 arms 85 mm. long; of the 10 IIBr series 7 

 are 4 (3 + 4), 2 are 2, and 1 is 1. The IIBr 1 series bears externally a IIIBr 3 (2 + 3) 

 series. The brachials are very short and their distal edges, which are parallel, are 

 very strongly produced and very spinous. 



Of the specimens from station 20, 1 has 14 arms 100 mm. long, there being 4 IIBr 

 4 (3 + 4) series present. Another has 13 arms 90 mm. long, with 3 IIBr 4 (3 + 4) 

 series. The third is much broken. 



One of the specimens from station 21 has 20 arms 115 mm. long; of the IIBr 

 series 8 are 4 (3+4) and 2 are 3. The brachials are very obliquely wedge-shaped, 

 about twice as broad as the longer side. The color is olive brown, with the dorsal 

 surface of the arms and the dorsal pole of the centrodorsal thickly and evenly sprinkled 

 with minute white dots which become much larger on the interbrachial articulations 

 and on the ventral perisome, and confluent along the sides of the pinnules. The 

 second specimen is undergoing adolescent autotomy; 3 IIBr series, 2 of 2 elements 

 and 1 of 4 (3 + 4), are just beginning to appear. 



Of the 3 specimens from station 26, 1 has 19 arms 95 mm. long; there are 9 IIBr 

 4 (3 + 4) series present. A second has 11 arms 95 mm. long; there is a single IIBr 

 4 (3 + 4) series. The third has 11 arms, there being a single IIBr 4 (3 + 4) series. 



The example from station 27 has 13 arms 120 mm. long; there are 3 IIBr 4 (3+4) 

 series. The brachials are very short with parallel edges and the distal edges strongly 

 produced and very spinous. 



One of the specimens from station 30 has 21 arms 130 mm. long; there are 9 

 IIBr series present, all 4 (3 + 4); the 2 IIIBr series are both 3 (2 + 3). The brachials 

 are short with slightly oblique ends; the dorsal surface is roughened and the distal
