ACTINOPODOUS HOLOTHURIOIDEA. 217 



epidei'mis and the jelly-like layer seem to be lost in preserved 

 specimens. The epidermis is of the beautiful bright color 

 given in the illustration, but even in the fresh condition, this 

 color changes to a dull red, and to green in patches which seem 

 to increase in extent and number as time goes on (compare figs. 

 59 and GO in PI. VII). On each of the dorsal ambulacra, there 

 were three slender papillae in the anterior part of the body ; the 

 posterior two of them are visible in the figure. Along the lateral 

 ambulacra, there were twelve or more appendages. In one case at 

 least, of the twelve the six posterior were longer and crowded, 

 while the anterior six were smaller and more scattered. On the 

 dorsal median line, in one specimen at least, there was a papilla 

 in the anterior part, at the tip of which the genital organ and 

 the stone-canal seemed to open. There was no pedicel on the 

 ventral median ambulacrum. The body was about 18 cm. long, and 

 9 cm. high at the anterior end. Like Thkel and Sluitek, I could 

 not And any calcareous bodies in any part of the body, and as 

 I used fresh specimens for observation, this could not have been 

 due to dissolution ; so I think, we must consider the species to be 

 without any calcareous spicules. 



Sluiter gives some anatomical details. I may say that pre- 

 served specimens came to assume appearances very much like 

 his figures (PL II., figs. 8, 9). According to Sluiter, the tentacles 

 are not all of equal size : the dorsal being smaller than the ventral. 

 This I am unable to see. Tliey all seem to be of a uniform size. 

 The oral field is 35 mm. in diameter. The end-shield of the 

 tentacles has a slcMider neck making each tentacle look like a 

 l30ttle. The diameter of the shield is about — 7 mm. Sluiter 

 mentions that the intestine lacks the usual convolutions and is 

 almost straight. In the specimen I dissected, the intestine dis-
