THE APODOUS HOLOTHURIANS 115 



Chieidota EOTIFERA. 



Si/iuiptd rolifcra Pnurtales, 1851, p. 15. 



Chlroihila rotifera Stimpsoii, 1860. Ludwig, ISSlrt, p. 41: pi. in. fig-s. 1-15. 



ChiriJota rolifcra LiKhvig, 1892&. 



Length. — Up to 100 mm.; usually about 50. 



Color. — Reddish or purplish, with light tentacles and numerous white 

 wheel-papilla\ 



DisTEiBUTioK. — Reported from Biscayne Bay, Florida (Pourtales); Brazil 

 (Ludwig, Verrill, Rathbun) ; Jamaica (Clark) ; Key West, Florida (Clark, 

 antea) ; and Bermuda (Clark). Apparently a typical West Indian species, with 

 the same distribution as Synaptula hydriformis. 



Remarks. — This is one of the best known and most distinctly characterized 

 species of the genus, and is of particular interest because it is viviparous — a 

 fact first noted by Ludwig ('Slo); the eggs undergo their development in the 

 body cavity of the mother, as in Synaptula hydriformis. It occurs commonly 

 i;nder stones and fragments of coral on sandy beaches or among living corals, 

 in shallow water, and is somewhat gregarious, a number often being found 

 under the same stone. 



Chieidota FEENA'NrD^NSis. 

 Chiridota fernandensis Ludwig, 1898r, p. 446. 



Length. — Up to 100 mm. 



Color. — In life, brownish yellow; in alcohol, whitish yellow; very numer- 

 ous small wheel-papillfp, white. 



Distribution. — Reported only from the Island of Juan Fernandez (Lud- 

 wig). 



Remarks. — This species was collected by Dr. Ludwig Plate in March, 1898. 

 He seems to have found it ([uite common, as some 20 specimens were taken. 

 Nothing is recorded of its habits or habitat. 



Chieidota stuhlmanni. 



Cliiroilota f:tulilrnanni Lampert, 18S)6, p. 67. 

 Chiridola stiililmanni Ostergren, 189S&. 



Length. — 80 mm. 



CoLOE. — Yellowish, with white wheel-papilhr, each of which has a rust-red 

 dot. 



Distribution. — Reported only from Tuml)atu, East Africa (Lampert). 



Remarks. — This seems to be a very well characterized species, of which, 

 however, only a single specimen is as yet known. The remarkably large (210- 

 2t)6/x), straight rods confined to the ambulacra, and the very numerous polian 

 vessels are striking features.
