not so large as those on the basal segments of Pp; P2 resembling P^ 

 but 15 mm. long with forty to forty-two squarish segments, the first 

 to- the fourth with slight dorsal projections; P3 similar, 12 mm. long; 

 P4 similar, 11 mm. long; P5 similar, 11 mm. long; the following 

 pinnules gradually decrease in length to 7 mm., then slowly increase 

 to 10 mm. distally; the carination of the proximal segments of the 

 lower pinnules becomes progressively less and less, disappearing 

 entirely after Pjo or Pij. 



Color dull olive green, the disk ambulacra and the perisome of 

 the pinnules dark brown. , 



Type.— Cat. No. 27490, U.S.N.M., from station 5356. 



This species is nearest to C. liartlauhi of Japan, but the cirri are 

 longer, much stouter, with more and shorter segments, which have 

 strongly swollen articulations. The division series and arm bases 

 lack the strongly everted and spinous distal edges so characteristic 

 of those of C. hartlauhi. 



Station 5856.— Four specimens, one with twenty, two with twenty- 

 six, and one with twenty-seven arms. 



Station 5414- — One small specimen with eleven arms about 90 mm.- 



long. 



Genus EUDIOCRINUS. 



EUDIOCRINUS INDIVISUS (Semper). 



Station 5356. — Five specimens, each with arms about 85 mm. long.

Genus AMPHIMETRA. 



AMPHIMETRA MILBERTI (J. Muller). 



Limborres Cave. — One specimen. 



" AMPHIMETRA VARIIPINNA (P. H. Carpenter). 



Station 5358. — One specimen with eleven arms 150 mm. long and 

 cirri XI, 34-41, 35 mm. to 37 mm. long. The cirri are rather more 

 slender than usual, the processes on the segments of the proximal 

 pinnules are less developed, and the general appearance is not so 

 rugged as is commonly the case. The animal is probably not quite 

 mature. 



Station 5481 . — One small specimen with twelve arms. 



Genus HIMEROMETRA. 



HIMEROMETRA MAGNIPINNA A. H. Clark. 



Vlugan Bay, Palawan. — One magnificent specimen with forty-two 

 arms 184 mm. long and cirri XXXIII, 29-35, 30 mm. long; the color 

 is a uniform deep violet.
