A MONOGRAPH OF THE EXISTING CRINOIDS 285 



In a third specimen from Madras, station 5 (No. 34), the cirri are XXIII, 26-27, 

 20 mm. long. The cirrus segments are subequal, all about twice as broad as long. 

 The arms are 150 mm. long. 



In the fourth specimen from Madras, station 5 (No. 42), the cirri are XXV, 19-24, 

 from 15 to 18 mm. long. The segments are subequal, half again as broad as long, 

 or twice as broad as long, or somewhat shorter distally than proximally. The color 

 is dull yellowish, the arms narrowly and frequently banded with purplish, becoming 

 mottled on the arm bases. 



The two specimens from Madras originally recorded as from Sadras are of 

 medium size. 



In the specimen from Waltair the cirri are XXX, 16-19. The cirrus segments are 

 subequal, half again as broad as long, slightly longer or slightly shorter. The arms 

 were probably about 75 mm. long. 



The five specimens from ?India are all of medium size. One of these has the 

 median brachial carination exceptionally well developed. In another the cirri are XX, 

 23-25, from 20 to 25 mm. long and resemble those of the type specimen. 



The two specimens recorded by Dr. Hubert Lyman Clark from Ceylon are 

 characteristic of the species. In one of them the dorsal pole of the centrodorsal is 

 7 mm. in diameter. The cirri are XXXIII, 27-29. All the cirrus segments are 

 short, as in carinala, and the cirri are of uniform width throughout. 



Carpenter said that the Leyden Museum contains a small and mutilated specimen 

 from the Indian Ocean that differs from the specimens obtained at Mauritius in the 

 somewhat larger relative size of the lower pinnules, and hi the greater smoothness of 

 the outer portion of the arms. The author examined this specimen at Leyden in 

 1910. The cirri are XV, 18-22, comparatively weak and slender. The cirrus seg- 

 ments are all subequal, all slightly broader than long, the last four tapering slightly. 

 The brachial carination is moderate. 



The specimen from the Indian Ocean in the Berlin Museum is much broken. 

 The centrodorsal and calyx have been laid open, showing beautifully the relationships 

 of the dorsal cavities of the calyx. 



Carpenter said that the four specimens from Java that he examined at the Ham- 

 burg Museum are more like specimens from Mauritius (carinata) than they are like 

 two others without locality, having XX-XXV cirri and more slender pinnules; but 

 the later pinnules are much less stiff than usual so that the arm ends have a more 

 feathery appearance than is the case in the form (carinata) from Mauritius. 



The specimen from the East Indies in the Copenhagen Museum has the brachial 

 carination but slightly marked. This specimen, and two others without locality, are 

 peculiar in being white. Presumably they were yellow in life. 



In the specimen from Eastern Asia the cirri are large and stout, XXIII, 20-23 

 (usually nearer the latter), from 20 to 25 mm. in length. In the proportions of the 

 component segments the cirri resemble those of T. carinata.
