ACTiNOPODOUS HOLOTHURIOIDEA. 105 



für jeden, der die beiden Tiere im Leben vor sich gesehen hat, 

 kaum wohlbegründet, da sowohl Lebensart, Farbe als ganzer 

 Habitus beider Tiere sehr verschieden sind, so wie auch die 

 Tentakel, und mehr oder weniger die Kalkablagerungen." (Slüiter 

 1887, pp. 191—2). 



Remarks :— The specimens before me are about 8 cm. Ion"- 

 being much contracted as indicated by numerous transverse 

 wrinkles on the body. They have a grayish brown ground color, 

 and along each of the dorsal ambulacra there is a series of irre«^- 

 ular dark brown spots about J cm. across. Besides these, there 

 are numerous minute spots of the same dark brown color, 

 scattered all over the bcdy. In one specimen, some spots on the 

 ventrum are of a somewhat large size instead of all the spots being 

 minute. Tentacles small, dark brown on the outer face. All 

 the ambulacral appendages, those on the dorsum as well as those 

 on the ventrum, have well -developed end-plates. They are there- 

 fore all pedicels. 



The circular ambulacral vessel is situated quite far back, 

 bemg 12 mm. apart from the calcareous ring, in agreement with 

 Sempee's statement. A single Pohan vesicle, about 13 mm. loner- 

 and one very much smaller dorsal stone-canal on the right of the 

 mesentery. Eeproductive organ somewhat developed, being over- 

 7 cm. in length. In one specimen, at the base of the left re- 

 spiratory tree, a branch of very slender Cuvierian bodies about 

 7 mm. in length and less than 1 mm. in breadth. Calcareous 

 bodies as described by Thkel.
