the largest anal papillae. In alcoholic specimens the color is 

 whitish, very thickly spotted and mottled with dark purplish 

 gray ; some specimens have a strongly yellow tinge. Mr. 

 Carpenter says in his notes on this species : " Certainly not of 

 a common variety. Found in but one place ; under loose slabs 

 of rock on north shore just southwest of Bailey's Bay. Color 

 of body ranging from yellowish-brown to dark blue. Color of 

 numerous and prominent tube-feet grayish-yellow." Professor 

 Heilprin^ based his new species, Seinpcria bermiidcnsis, upon a 

 single specimen collected on the north shore west of Flatts' 

 village. He distinguished it from C. punctata Ludw. on ac- 

 count of (i) the different color, (2) the different arrangement of 

 the tentacles, (3) the number of Polian vesicles, and (4) the 

 number of filaments composing the genital bundles. After 

 what has been said above it hardly seems necessary to state that 

 these characteristics are more or less variable, and while one of 

 my specimens is exactly like Ludwig's'^ type, another is almost 

 as nearly like Heilprin's. Seinpcria bcrnmdcnsis must therefore 

 be reduced from the list of valid species to the already crowded 

 ranks of synonyms. 



The collection of 1898 contains four specimens of a small 

 holothurian not represented in the collection of 1897. These 

 four were in the same bottle with H. surinanicnsis and were 

 apparently not distinguished from that species by the collector. 

 They came from the same localities but were probably less 

 common than that form. The alcoholic specimens are easily 

 picked out from those of surinanicjisis by the position of the 

 anus, the flattened ventral surface, the tendency of the feet to 

 form regular longitudinal series and the color. They were 

 readily identified as H. captiva Ludw., the large bright yellow 

 bunch of Cuvierian tubes being very noticeable. It is attached 

 well up on the respiratory tree some little distance from the 

 cloaca. Papillae are quite numerous and prominent on the 

 dorsal surface. Pedicels are numerous on the middle and rear 

 of the ventral surface, indistinctly arranged in three series. 

 The specimens var>' in size from 30 mm. by 12 to 70 mm.
