ACTINOPODOUS HOLOTHÜRIOIDEA. 47 



the ventral ; and a liglitor colored area always present around 

 the anus. 



Remarks : — One of the sepcimens in the fresh state was 

 probably about 30 cm. long. In alcoliol it is much contracted 

 and measîures 14 x 10 cm. 



I have the following notes on a fresh specimen. Dorsum ; 

 purplish black with large, irregular, cloud-like, yellow patches, 

 generally transverse in direction. These are most numerous on 

 the two dorsal ambulacral zones. A few pedicels on these lines. 

 More laterally there are finely indented grayisli patches. Ven- 

 trum white. Pedicels most numerous on the median and the 

 two lateral ambulacral zones. The lighter ventral area extends 

 up to and surrounds the anus, becoming somewhat gray in this 

 part. 



All the alcoholic specimens are much distorted in shape. One 

 which shows least distortion measures 14.5 cm. by 0.5 cm. 

 Dorsum chocolate-brown. Yentrum much lighter ; toward the sides 

 dark lines bounding small quadrilateral areas. The liglit ventral 

 color extends into the area around the anus, which is also more or 

 less distinctly marked into small quadrilateral areas. The bound- 

 ary line between the dark dorsal and the light ventral areas is 

 very irregular and broken ; marked out into quadrilateral areas 

 of a lighter color, partly corresponding to the yellow patches of 

 the fresh specimen, and partly to the gray patches. In some 

 specimens the marking extends over the dorsal surface. Tentacles 

 20. Mouth slightly ventral, anus slightly dorsal. 



Small X- shaped calcareous bodies with the ends of the 

 crossed pieces dividing dichotomously about three times, looking 

 like the tendrils of a climbing plant. In many cases there is 

 in the middle of the middle piece a small brancli on one side.
