Clart — Description of Unstalked Crinoids from Eastern Asia. 181 



crowded marginal rows, and are jcxix, 34-36, 20 mm. to 27 mm. long; 

 tlic longest proximal cirrus segments are usually from one-third to one- 

 half again as broad as long, and the outer cirrus segments are two and 

 one-half or three times as broad as long; the eighth or ninth and follow- 

 ing bear prominent, rather slender, dorsal spines which in the outer part 

 of the cirri become inure or less broadened laterally, forming short high 

 transverse ridges or ending in a more or less completely bifurcated tip; 

 toward the extremity of the cirrus the dorsal spines again resume their 

 normal character. There are aboul thirty-eight arms about i»> mm. long; 

 there are live n P>r series of J ( .", f) ami four of 2; there are eleven III Br 

 series of 4 (.'! t 4), and four of 2; the single IV Br series is 4 (34-4); the 

 radials, division series and anus are similar to those of specimens from 

 Singapore. 



The other specimen is similar ; there are about forty arms ; the ten n Br 

 series are 4 (3+4); three of the in Br series are L', the remainder being 

 I (.". f-4); two iv Br series are present, one of 2 and one of 4 (."! 1 ). The 

 cirri are xxvni, 33-35, about 25 mm. long. 



Both specimens are dull pinkish with purple cirri, the earlier segments 

 of the latter with white borders and a white dorsal surface. 



Except tor the greater number of arms these specimens agree perfectly 

 with a series at hand from Singapore and from the Philippine Islands. 



This species differs from the Australian Zygomelra elegans in possessing 

 fewer arms, greater regularity in the division series, smaller and shorter 

 cirri which have fewer segments, and broader and less strongly rounded 

 division series. 



Catoptometra rubroflava (A. II. Clark). 



Locality. — Eight miles outside of Hong Kong harbor (22° 12' N. lat., 

 114° 15' E. Ions.); 14 fathoms; November Hi, 1911. 



Remarks. — Five specimens were secured; the best of these has thirteen 

 arms 100 mm. Ions; the three n Br series are 4 (3+4); the cirri are 

 xxvii, 16-17, about 1"> mm. long; the longest proximal cirrus segments 

 are nearly or quite as long as the median dorsoventral diameter. A 

 second specimen has twelve arms about 110mm. long; the two n Brseries 

 are 4 ( ."> 4); the cirri are xxvm, L5, about 13 mm. long. A third has 

 also twelve arms, the two n Br series being 4 (:'>+4); there are 14-16 

 cirrus segments. A small specimen has ten arms 60 mm. long. The fifth 

 is much broken. 



The color in life appears to have been bright yellow broadly banded 

 with bright red, as in the ty] f the species. 



These specimens agree well with the type and with other examples of 

 C. rubroflava from southern Japan. 



Family MARIAMETRIDjE.

Locality. — Fight miles outside of Hong Kong harbor (22° 12' .\. lat., 

 114° l.V F. long.); U fathoms; November 16, 1911.
