EEPORT GIST THE HOLOTHUEIOIDEA, 
27 
Syncipta dolahrifera, Stimpson, 1856. 
Tentacles twelve, with about fourteen digits. Deposits crowded. Anchor-plates 
mostly with ten perforations, the middle largest. Anchors a little larger than 
the plates, with the extremity of the handle also provided with a double hook, 
though of very small size. . 
Habitat . — Port Jackson (Stimpson). 
Synapta oceanica [Holotliiiria), Lesson, 1830 ; Jteger, 1833. 
Tentacles ten, flat, pinnate or plumrdose. Six membranous bands along the body ; 
symmetrical, round protuberances occupy the intervals between these bands. 
Anchors present. Very unsatisfactory description. 
Habitat . — Very common at Tahiti (Lesson). 
There is no doubt that the abr;ve description is very incorrect. Lesson speaks 
wrongly of six longitudinal bands, and there is reason to believe that he also 
erred when stating the tentacles to be ten. Judging from the pinnate tentacles, 
from the presence of longitudmal series of round protuberances, from the length 
(3 feet) of the body, and, finally, from the locality itself, where the animal 
is found in abundance, I am much inchued to refer the species of Lesson to 
Jfeger’s Synapta bcsclii, which is known to be common at the Society Islands. 
Selenka and Semper referred Lesson’s species to those with twelve tentacles. 
VI. Tentacles ten. 
Synapta reticulata, Semper, 1868. 
Tentacles with ten to twelve thick, distant digits. Cartilaginous ring present, with 
large holes posteriorly. Polian vesicles eight to ten. Madreporic canal single. 
Anchor-arms smooth. Anclior-plates symmetrical, with seven larger dentate 
holes and some smaller smooth ones. Miliary granules rosette-shaped. 
Habitat . — Bohol (Semper). 
B. Tentacles digitate, with few, never more than five digits. Anchor-plates, almost without 
exception, asymmetrical, with numerous often smooth holes, which for the most part 
are irregularly arranged ; very seldom a handle at the articular end, which is often 
more or less distinctly truncated, and has the bow indistinct or even absent. 
Circumference of the plates mostly uneven or incomplete. 
I. Tentacles thirteen. 
Synapta uncinata, Hutton, 1872. 
Tentacles very short, merely tubercles, with two incurved hooks at the end of each. 
Anchor-flukes equal. Very unsatisfactory description. 
Habitat . — New Zealand (Hutton).
