 kaum wohlbogviindot, da sowohl Lebensart, Farbc; als ganzer 

 Habifcas beider Tioro sohr verschiodon sind, so wio audi die

Remarks : — The specimens before rao are about 8 cm. long, 

 being much contracted as indicated by numerous transverse 

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

 and along each of the dorsal ambulacra there is a series of irreg- 

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

 are numerous minute spots of the same dark brown color, 

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

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

 minute. Tentacles small, dark l)rown on the outer face. AW 

 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, 

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

 Semper's statement. A single Polian vesicle, about 13 mm. long; 

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

 mesentery. Reproductive 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 Cuvicrian bodies about 

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

 bodies as described ])y Thkel.
