62 SPOLIA ZEYLANTCA. 



writers to imperfectly developed tables. They generally 

 consist of two or three stout rods, sometimes trident-shaped, 

 at other times like the tower of a typical Holothurian table. 

 The speculations of previous writers as to the homology of 

 these bodies with vestigial tables have little substantial support. 



Remarks. — In the peculiar formation of the calcareous ring 

 as well as in the general nature of the deposits this species 

 shows relationship with H. argus and the allied species, from 

 which, however, it differs in the abnormal number of its 

 tentacles and in the arrangement of the ventral pedicels 



General Distribution. — Indo-Pacific region. 



HoLOTHUEiA GLABEERiMA, Selenka.

Holothuria glaberrima, Selenka 1867 (37) ; Semper 1868 (38) ; 



Lampert 1885 (19), 1896 (21) ; Theel 1886 (42) ; 



Ludwig 1887 (28) ; Clark 1901 (9) ; Koehler & 



Vaney 1908 (17). 



Holothuria erinaceus, Semper 1868 (38) ; Lampert 1885 (19) ; 



Theel 1886 (42). 

 Holothuria erinaceus, var. pygmssa, Semper 1868 (38) ; 



Lampert 1885 (19). 

 One specimen from Ternate (Frankfiirt Museum). 

 Lampert (21) and Koehler & Vaney (17) have discussed the 

 relationship of these forms and have thrown doubt upon 

 Lampert's earlier opinion, with which Ludwig (31) agreed, 

 that Holothuria lubrica, Holothuria glaberrima, Holothuria 

 erinaceus, Holothuria erinaceus var. pygmsea, and Holothuria 

 parva are identical. Although all these forms are undoubtedly 

 related, I propose following Lampert and Koehler & Vaney m. 

 retaining Holothuria lubrica and Holothtiria parva as distinct 

 species, while including the remaining three under the name 

 glabe/rrima. 



External Characters. — The colour of the bivium is dark 

 brown and the trivium is a lighter colour. There are twenty 

 dark brown tentacles. On the bivium there are thinly- 

 scattered papilltje of a small size and on the triviimi there are
