A MONOGKAPH OF THE EXISTING CRINOID8 433 



undivided arm exteriorly. The IVBr axillaries bear a VBr series on the side oppo- 

 site that from which the IVBr series arises on the IIIBr axillary and an midividcd 

 arm on the other face. The division series are narrow and widely separated and 

 the arms are very slender. The brachials have somewhat produced distal edges 

 armed with numerous fine spines. 



Another specimen from Soutre has 59 arras 135 mm. in length. The 10 IIBr 

 series are 4 (3 + 4), and all the subsequent series are 2. 



A third specimen from Soutre has 58 arms 145 mm. long. Of the 10 IIBr 

 aeries, 9 are 4 (3 + 4) and 1 is 2. The following division series are all 2. The radials 

 are about twice as broad as their median length. The division series are narrow 

 and widely separated and the arms are very slender. The controdorsal is very 

 small and is sharply stellate. 



A fourth specimen from Soutre has 52 arms 170 mm. long. Of the 10 IIBr 

 series, 7 are 2, 1 is 4 (3 + 4), 1 is 3, and 1 is 3 (1 + 2 + 3). The following division series 

 are 2 except for one IIIBr series, which consists of a single axillary ossicle. The 

 centrodorsal is extremely small, its diameter being less than the length of the radials. 

 The radials are triangular, with their inner apices slightly truncated. 



The fifth specimen from Soutre has 41 arms 150 mm. long. The 10 IIBr series 

 are 4 (3 + 4). Of the 20 IIIBr series, 18 are 1 and 2 are 4 (3 + 4). There is a single 

 IVBr 4 (3 + 4) series next to the midradial line. The division series are narrow and 

 widely separated and the arms are very slender. The centrodorsal is greatly reduced 

 and stellate, the dorsal surface not rising above that of the radial pentagon. 



In the specimen from New Britain there are 3 or 4 postradial axillaries. 



The example from Suva, Fiji, has about 40 arms.

Geographical range. — From the Maldive Islands eastward to New Britain, Fiji, 

 and the Macclesfield Bank. 



Bathymetrical range. — Littoral and sublittoral; the only depth records are 13 

 and 55 meters. 



Remarks. — Hartlaub sent the type specimen of this species to Dr. P. H. Car- 

 penter, who said that he was unable to identify it with C. mvltifda. The grounds 

 upon which Carpenter and Hartlaub considered it distinct from C. midiifda are the
