A MONOGRAPH OF THE EXISTING CRINOIDS 129 



The specimen from Albatross station 2342 has 21 arms. 



Of the 2 specimens from Albatross station 2345, 1 has 11 and one 19 arms. 



The specimen from Albatross stations 2160-2162 is a large ll-armed example. 



The example from Albatross station 2333 has 20 arms. 



From Albatross station 2341 there is a small specimen with 10 arms. 



Of the 2 specimens from Albatross station 2326, 1 is a 13-armed adult and the 

 other is a 10-armed young with a central mouth. 



Of the 2 specimens from Albatross station 2320, 3 have 12 and 1 has 18 arms. 



One 13-armed and one 18-armed specimen are from Albatross station 2327. 



The material from off La Chorrera, Cuba, consists of a very small ll-armed 

 specimen and fragments of others, with IIBr series. 



From Blake station 139 there is a large specimen with 19 arms. 



Blake station 134 yielded one very fine specimen with between 16 and 20 arms; 

 the division series are strongly "wall-sided." 



From Blake station 152 there is a large example with 20 arms. 



The 2 large specimens from Blake station 148 each have 20 arms, which in 1 

 are about 80 mm., in the other about 100 mm. in length. The division series and lower 

 brachials in both of these are dark brown in color. 



Of the specimens from Blake station 156, 1 has 14 arms about 80 mm. long, 1 is 

 large with 19 arms, and 2 have 20 arms; another is medium sized. A young 10-armed 

 specimen has an arm length of between 55 and 60 mm. The IBri are entirely free 

 laterally, and laterally rounded. The IBr2 (axillaries) have a somewhat excavated 

 surface. The brachials are smooth, rounded dorsally, and triangular. The tliird and 

 fourth segments of the proximal pinnules have an unusually strong spinous production. 

 This specimen, which was called meridionalis-carinata by Hartlaub, is the young of 

 this species. 



From Blake station 157 there are 2 specimens with 16-20 arms, and an ll-armed 

 young with relatively slender arms. The color is white, with the syzygial pairs 

 brownish. The IBri are free laterally, and the arms are smooth dorsally. The 

 centrodorsal is slightly convex. The IBr2 (axillaries) are broader than the IBr,. 



Of the 5 specimens from Blake station 158, 3 have 20 arms and 2 have nearly 20 

 arms. All are large or medium sized. One of the 20-armed specimens is violet in 

 color and has "wall-sided" division series. 



Of the 4 specimens from Blake station 189, 1 has 19 arms, which were probably 

 about 150 mm. long, and 3 are large with 16-20 arms and the division series laterally 

 free. 



Of the 4 specimens from between Dominica and Martinique in 292-695 meters, 

 2 have apparently 11 arms, 1 has 12 arms, and 1 has between 15 and 20 arms. In 

 color they are all dark brown with lighter cirri. The arms in all are smooth dorsally. 

 The centrodorsal of all is curious in being rather small, and not discoidal but more or 

 less hemispherical. The cirri have 3 short basal segments. The IBr, are always 

 free laterally. The elements of the IBr series have in part strongly produced ends 

 and a sunken dorsal surface, and the same may be true of the lower brachials; this 

 gives the profile of this portion of the animals a scalloped appearance. 



The single small specimen from Blake station 206 has 13 arms and "wall-sided" 

 division series.
