ACTINOPODOUS HOLOTHURIOIDEA. 93 



the most a few short teeth along the sides. Such rods are 

 found especially in the dorsal papillae. 



The above four kinds of calcareous deposits we may consider 

 as appertaining to fully grown var. mœUL But there are some 

 striking facts brought out when we examine the young. Among 

 the numerous specimens fi'om Kominato (No. 1244) there are some 

 young. Examination of the two smallest, respectively 2.3x0.8 

 cm. and 3.5x1.0 cm., shows that these contain granulated rods as 

 usual, but smooth rods I have not succeeded in detecting. They 

 have no H- shaped bodies. Of tables they have a few. 

 These mostly consist of the disk alone, sometimes large and 

 sometimes with only the central holes. They are found in both 

 the dorsum and the ventrum, but more frequently in the former. 

 They are never present in any large number, and may easily be 

 overlooked. They are different from those of //. cinemscens. In 

 a somewhat larger (5.5x2.4 cm.) specimen from Kominato (No. 

 1244/), and in another from Natsui (No. 1249, 4.0 x1.3 cm.), 

 there are granulated rods and a few tables, but not the H-shaped 

 bodies. Curiously enough, that specimen from Kominato possesses 

 some .well- developed tables with tall spire. This is built of four 

 slender pillars with 1 — 3 cross-beams, but is without a special crown. 

 In a Kominato specimen (No. 1224 d) of 7x2 cm., I was able to 

 detect just one table in an area of about one square centimetre, 

 so that tables may remain here and there even in tolerably 

 large specimens. 



Remarks : — If we now tabulate the results brought out 

 above, they will appear thus : —
