THE VOYAGE OF H.M.S. CHALLENGER. 
Molucca Islands, Navigator and Fiji Islands (according to Semper), Darros Island 
(Bell). 
(Mus. Holm.) Several specimens from unknown localities. In addition to C-shaped 
deposits and tables, I find some very scattered incomplete rosettes. 
Stichopus haytiensis, Semper, 1868. 
Tentacles twenty. Papillse on rather prominent protuberances, arranged in four rows 
along the dorsal surface. Spire of the tables terminating in twelve teeth. 
Habitat . — Hayti (Semper), Puerto CabeUo (Ludwig). 
Differs from the preeeding species apparently in that the dorsal papillae form four simple 
rows, and in having the ventral pedicels sparsely distributed in “five” broad series. 
Stichopus errans, Ludwig, 1875. 
Tentacles nineteen. Papillae, fewer in number, situated on low warts. Spire of the 
tables terminating in twelve or sixteen teeth. 
Habitat . — Barbados (Ludwig). 
The description is not fully satisfactory. With regard to the’ papillae, Ludwig only 
says that they seem to belong to the ambulacra alone, but does not explain how 
they are arranged. 
(Mus. Holm.) One specimen dredged at St. Thomas. It is very wrinkled and con- 
tracted, so that it is impossible to state the arrangement of the dorsal papillae; as 
it seems to me, they are placed on low warts forming a row along the sides of 
the body, and possibly such warts may even be observed on the two dorsal 
ambulacra. I cannot decide whether or no there are small papillae on the 
interambulacra. Tentacles nineteen (or eighteen ?). The radial pieces of the 
calcareous ring, excepting the middle ventral one, are provided with a short 
posterior, deeply incised prolongation. The deposits are like those described by 
Ludwig, excepting that the greater part of the tables are destitute of disks or have 
• rudimentary ones. The species is possibly identical with the preceding. 
h. Deposits — 0-shaped bodies ; tables like those in the preceding 
species; and large robust tables remarkable in having the 
conical spire terminating in a single point and possessing 
several transverse beams. 
Stichopus horrens, Selenka, 1867. 
Tentacles twenty. Papillse on rather large conical prominences, arranged in four rows 
along the dorsal surface. In addition to C-shaped bodies, incomplete rosettes, and 
small tables, like those in the preceding species terminating in twelve to sixteen 
teeth, much larger tables of the same construction are found ; and, besides, 
large robust tables with the conical spire terminating in a single point. 
Habitat . — Society Islands (Selenka).
