REPOET OX THE HOLOTHUEIOIDEA.

2. Pedicels arranged in one or tiro rows on each amhidacruni. 
a. Deposits — roundish or oval buttons with a few perforations and 
often with large rounded knobs, besides minute reticulate cups. 
Cucii maria guinquesemita, Selenka, 1867. 
The cups are irregularly reticulate, with the spinous rim complete or incomplete. The ^ 
oval buttons form a thick layer, are smooth and more or less swollen, always with 
four holes. Calcareous ring with slender posterior prolongations. 
Habitat . — Mendocino in California and (?) Charleston (Selenka).

marinus, Eondelet, 1555. Echinus coriaceus ad os Jimbriatus, Plancus, 1760,

Cladodactyla doliolum, Grube, 1840. Cucumaria doliolum, Sars, 1857; 
Selenka, 1867. (?) Cucumaria cylindrica. Semper, 1868. 
Body cylindrical or slightly pentangular. The closely packed innumerable knobbed 
biittons are of unequal size, the larger having more holes and knobs than the 
smaller. The flat cups are numerous, minute, formed by three curved spokes 
and a rim with short processes. According to Selenka, three ventral pieces of the 
calcareous ring are united together. 
Habitat — West coast of France (Barrois), Arrabida (GreefF), Mediterranean Sea 
(Ludwig, Marion, v. Marenzeller, Sars, Groeffe, &c.) (?), Mauritius (Semper, 
Hoffmann). 
Brady and Eobertson (1871) described an animal, dredged in the Firth of Clyde, under 
the name of Cucumaria pentactes, which probably may be identical with this 
species or the next one, but unfortunately their description is too unsatisfactory 
to decide it. They do not mention anything about the “ cups.” 
(Mus. Holm.) Two specimens dredged at Naples and one at Portor^ agreeing with 
the description of Sars, &c. The buttons often seem to have about eight holes 
and twelve to fifteen knobs, but they have not seldom fewer, or even more. 
Cucnnmria lactea (Ocnus), Forbes, 1841 ; Diiben and Koren, 1844. Holothuria 
hadotrice, Dali yell, 1851. 
Habitat . — British Islands (Hodge, Forbes, MTntosh, Mbbius and Biitschh, Leshe and 
Herdman) ; west coast of Norway at Bergen and Christiansund (Diiben and 
Koren, Sars, Danielssen). 
This species must be very nearly allied to the preceding one, differing from it mainly 
by the simple rows of pedicels. 
(Mti.s. Holm.) Very numerous specimens from the west coast of Sweden and Norway.
