HOLOTHURIOIDEA. 205 



The mouth is surrounded hy a crown of papillae. 



The number of tentacles is different in each specimen. There are 1 8 in the largest, 

 14 in the next, and 16 in the smallest. In the two latter it is highly probable that 

 some tentacles are retracted. 



There are four irregular rows of protuberances one row along each side of the 

 body. In this it differs from Stichopus chloronotus, which has two double rows on 

 the dorsal surface. The pedicels are irregularly scattered on the ventral surface, 

 showing a slight indication of forming three rows. 



The deposits agree with those of Stichopus chloronotus, except that the C-shaped 

 deposits are very rare indeed. 



These two spirit specimens are very much darker in colour than the spirit specimen 

 of St. chloronotus, the former being a dark chocolate-brown. 



I consider that the differences between these specimens and St. chloronotus justify 

 the formation of a new variety. 



Stichopus variegatus, Semper. 



St. naso, Haacke, 1880. See Semper (2), Theel (7). 



Two specimens from S.W. of Periya Paar (Stn. LV.), 11-24 fathoms. 



Lengths, 85 millims. and 75 millims. 



The specimens are very much contracted and in a poor state of preservation. 



The tentacles in one specimen are dark brown and in the other yellow. I am 

 unable to count them owing to their poor state of preservation, but in other respects 

 the specimens agree with Semper' s description. 



The pedicels are arranged in three series on the ventral surface, each series having 

 about four rows. 



Distribution : Lido-Pacific, Mauritius, E. Indies, Ceylon. 



Note. While this Report was in the press another specimen (from Gulf of Manaar, 

 February, 1902) was found which is nearly related to Phyllophorus cebuensis, 

 but may be distinct, as it differs in the deposits, having additional rosette- 

 shaped buttons.
