74 SPOLIA ZEYLANICA. 



jDerforated by ten or a dozen holes, but in older specimens 

 there are generally only four peripheral holes. The tower is 

 35 [)^ high and consists of four uprights connected by one 

 cross beam, and is terminated by a ring bearing eight or ten 

 spines. The buttons are 50 ^ in length and have three pairs 

 of holes. There are also perforated plates in pedicels and 

 irregular spinous or perforated supporting rods in the papillae. 



General Distribution. — A common Indo-Pacific form. 



Remarks. — Although this si:)ecies should, strictly speaking, be 

 named leucospilota, the name vagabunda is in such universal 

 use, that the demands of priority should be waived. This has 

 evidently been the view of every writer since Ludwig showed 

 in 1875 that SticJiopus leucospilota, Brandt, is identical with 

 Holothuria vagabunda, Selenka. At any rate no one has used the 

 rightful name, and I see no reason to adopt a different course. 



In 1886 Theel suggested that H. vagabunda and H. lagsena 

 were identical, and in 1895 Koehler (16), after an examination 

 of specimens from different localities, proposed to unite the 

 two, but in 1908 Koehler & Vaney did not give H. lagsena 

 as a synonym of the species, so that one is led to conclude that 

 Koehler did not maintain his earlier view. I have had no 

 opportunity of examining a specimen agreeing with H. 

 lagaena, so that I am unable to throw any light upon the 

 question.
