140 THE BERMUDA ISLANDS. 



the variously branched genital organs, which are disposed in 

 two great bundles. Tentacular vesicles present. Two Polian 

 vesicles. Calcareous ring with long back processes. 



Calcareous bodies in the form of stools very numerous (PI. 

 13, fig. 16). C-shaped bodies very scanty, and possibly in 

 some cases entirely wanting. 



Color black, somewhat more intensely so on the dorsal sur- 

 face, becoming Vandyke brown or chocolate in alcohol. 



Length, about one foot; width of corresponding animal 

 about three inches. 



Abundant over the sandy floor of the entrance to Harring- 

 ton Sound, opposite Flatts Village, in Harrington Sound, and 

 in Castle Harbor, whence it was obtained in several of our 

 dredgings. 



I have little doubt that this species is the dark-brown form 

 which is referred to by Theel as having been obtained by the 

 officers of the Challenger at the Bermudas, and which is 

 doubtfully referred by that authority to Semper's Stichopus 

 Haytiensis (Report on the Holothuroidea, Challenger Reports, 

 Zoology, XIV, p. 162). Only a single specimen appears to have 

 been obtained, which when examined was too deformed to 

 permit of positive specific determination. I cannot agree 

 with The'eFs determination. Apart from the differences which 

 Theel himself points out, is the great difference in coloring. 

 Semper (Reisen, Philippinen, Holothurien, 1868, p. 75) states 

 that his species is dark chocolate-brown, blotched with yellow 

 spots, which form five longitudinal bands, corresponding to 

 the interradii. No such coloration is visible in our species, 

 although probably we observed as many as a hundred in- 

 dividuals, all of which were uniformly black. Semper's de- 

 scription of the coloring of Stichopus Haytiensis is re-stated by 

 Lam pert. 



Stichopus xanthomela, n. sp. (PI. 12, fig. 1 ; PI. 13, fig. 3.) 



Body stout, flattened ventrally, and bearing on the basal 

 margin two rows (one row on each side, as in the preceding
