REPOUT ON THE HOLOTHURIOIDEA. 
201 
Miilleria ecJiinites, Jaeger, 1833; Semper, 1868. 
Deposits — small incomplete rosettes, and large simple or irregularly branched rods, 
having, hke the former, the ends of the arms dichotomous. 
Habitat. — Indian Ocean (Ludwig), Celebes (Jseger), Padang in Sumatra (Ludwig). 
(Mus. Holm.) One specimen from the Fiji Islands. Length, 140 to 150 mm. Colour 
in alcohol, blackish-brown, with the pedicels, papillae, and tentacles lighter. 
Tentacles twenty. Anal teeth of ordinary size. Mouth ventral in position, 
surrounded by a brim of small papiUae. The ventral cylindrical pedicels very 
distinctly arranged in three series, though a few pedicels may be found even on 
the interambulacra. Dorsal papillae small, not larger than the pedicels, closely 
placed, and seemingly issuing from minute warts. Deposits crowded, of two kinds 
— large rod-like bodies, mostly unbranched, or with the ends alone dichotomously 
branched; and small dichotomously branched incomplete rosettes of the usual shape. 
There exist great variations in size between these two extremes, but a good many 
transitional forms may be found among them. The papillae have very rudimentary 
terminal plates. The species evidently bears the nearest resemblance to Miilleria 
miliaris and Miilleria lecanora. 
B. Tentacles twenty-five to twenty-seven. 
Mulleria mauritiana [Holothuria) , Quoy and Gaimard, 1833; Brandt, 1835 ; Selenka, 
1868. Mulleria varians, Selenka, 1867. 
Tentacles twenty-five. Deposits — in the dorsal integument longer and shorter rods 
with small processes running out from the sides, and with the ends spinous or 
more or less distinctly dichotomous ; in the ventral perisome small smooth oval 
grains and larger smooth unbranched rods with the ends slightly rough. 
Habitat. — Philippine Islands (Semper), Society Islands (Selenka), Navigator Islands 
(Semper), Fiji Islands and Sandwich Islands (Selenka), Querimba and Pmd Sea 
(Semper), Mauritius (Quoy and Gaimard, Haacke, Ludwig), Amboina, Java, 
Padang, Pulo Penang (Ludwig), Mozambique, Darros Island, , and (?) Amirante 
Islands (Bell). 
(jMus. Holm.) Several individuals from Pulo Penang, Navigator Islands, Fiji Islands, 
Tahiti, Marquesas, Paumatu, Apia, and Eooa. Tentacles varying from twenty-four 
to twenty-six. The largest specimen attains a length of 160 mm. Colour 
auburn, lighter on the ventral surface ; white rings surrounding the bases of the 
papilla;, especially obvious on the sides of the body, and in the neighboiu’hood of 
the anus. Pedicels very crowded, not arranged in distinct series. The conical 
dorsal papilla; are of about the same size as the pedicels. Deposits of the dorsal 
surface — incomplete rosettes ; and numerous elongate rods which are granulated 
or provided with numerous crowded simple or branched, unequal protuberances. 
Deposits of the ventral surface — more or less complete rosettes ; numerous elliptic 
bodies which are smooth or p>rovided with incisions ; and rods resembling those in 
the dorsal perisome, but smooth or with less prominent protuberances.
