THE VOYAGE OF H.M.S. CHALLENGER. 
Mulleria agassizii, Selenka, 1867. Actinopyga agassizii, Verrill, 1867-1871. 
Tentacles twenty-five to twenty-seven. Deposits — in the dorsal perisome minute 
X -shaped bodies, in the ventral minute simple rods. Pedicels in three 
longitudinal series. 
Habitat. — Florida, Tortugas and Hayti (Selenka). 
Possibly only a variety of the former. 
Mulleria guamensis (Holothuria), Quoy and Gaimard, 1833 ; Brandt, 1835. 
Habitat. — Guam (Quoy and Gaimard). 
Tentacles twenty-six. A very dubious form, which needs re-examination. 
Mulleria sp., Walter, 1885. 
Habitat. — Ceylon (Walter). 
Genns 4. Holothuria, Linne, 1758. 
Tentacles twenty, exceptionally more or less. Ambulacral appendages — pedicels 
alone or papillae alone, or both papillae and pedicels ; the former placed on the 
dorsal surface, the latter on the ventral. These ventral pedicels are seldom 
arranged in longitudinal series. A single bundle of genital tubes situated on the 
left side of the dorsal mesentery. Anus devoid of calcareous teeth, but sometimes 
stellate. C-shaped deposits absent. 
A. Deposits — more or less incomplete rosettes. 
I. Anus more distinctly stellate. 
Holothuria marmorata (Bohadschia), Jaeger, 1833 ; Semper, 1868 ; Ludwig, 1881. 
Sporadipus ualanensis (subgenus Colpochirota) , Brandt, 1835. Holothuria 
ualensis, Selenka, 1867. Holothuria hrandtii, Selenka, 1867 and 1868. 
Holothuria utrimquestigmosa, Haacke, 1880 (according to Ludwig, 1881). 
Habitat. — Philippine Islands (Semper), Nicobar Islands (Semper), Java (Selenka), 
Celebes (Jaeger), Fiji Islands (Semper), Amboina (Ludwig), Geelvink Bay at New 
Guinea (Ludwig), Mauritius (Haacke and Ludwig), Bonin Islands (Semper), Ualan 
in Caroline Islands (Brandt). 
(Mus. Holm.) One specimen brought home from Mauritius. Length, 120 mm. 
Colour — dorsal surface auburn, with some large spots or bands of yellowish- 
white colour, ventral surface yellowish-white ; here and there, especially along 
the sides of the body, a large darker violet spot may be found within 
a light yellowish space. The ambulacral appendages have the shape of 
cylindrical pedicels, which, however, are smaller on the dorsal surface.
