ACTINOPODOUS HOLOTHURIOIDEA. 93 



tho most a few short teeth along the sides. Sucli rods are 

 found especially in the dorsal papillae. 



The above four kinds of calcareous deposits wo may consider 

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

 striking facts brought out when we examine the young. ^Vmong 

 tlie numerous specimens from Kominato (No. 1244) tliero are some 

 young. Examination of the two smallest, respectively 2.3 x 0.8 

 cm. and 3.5 x 1.0 cm., shows that these contain granulated rods as 

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

 have no II- 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 UKJre frequently in the former. 

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

 overlooked. They are different from those of //. cinerascens. 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 gi-anulated rods and a few tables, but not the II- 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, Imt is without a special crown. 

 In a Kominato specimen (No. 1224 d) of 7 x 2 cm., I was able to 

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

 so that tables may remain hero and there even in toleralily 

 large specimens.

 above, they wiU appear thus : —
