ECHINODERMATA.

Cassiduloidea. 
Martens (1. c.) mentions Echinolampas oviformis and Nucleolus (? for Nu~ 
cleolites) epigomis (Mart.) as East-Indian. 
Clypeastroidea. 
Clypeastcr testudinarius (Gray), C. reticidatus (Gmel.), C. placunarius 
(Lam.), Laycmum honanni (Agas.), L. depressum (Less.), L. decag(mum{ljQ^B.)f 
Arachnoides placenta (L.), Lohophora hijissa (Lam.), and L. hiforis (Gmel.) 
are mentioned by Martens (1. c.) as found in the East Indies, and are generally 
rcdcscribed. 
Galeritoidea, 
Echinoneus minor (Leske) is mentioned by Martens (/. c.) as found at 
Larentuka, and E. cyclostomus and E. serialis are indicated as East-Indian 
forms. 
Echinometridcs. 
Echinometra lucunter (L.), E. {Acrocladia) mammillata (L.), E. trigonaria 
(Lam.), and E. {Colohocentrotus, Brandt = Podophora, Ag.) atrata (L.) are 
recorded as East-Indian, and redescribed by Martens (1. c.). 
Echinometra {Acrocladia) planispina^ Martens, sp. n.. Verb, zopl.-bot. Ges. 
in Wien, 1866, p. 381, from the Red Sea. The spines of this species are 
not triangular as in A. trigonaria, nor club-shaped as in A. mammillata, 
nor cylindrical as in another Red Sea species, A. hlainmllei, but are small 
and pointed, and the corona is covered with true spines. 
Echinida. 
Diadema calamare (Pallas), D. spinosissimum (Lam.), E. samgnyi (Mich.), 
and Z>. radiatum (Leske) are recorded as East-Indian by Martens (/. c.), and 
described at length. 
Echinus sardicus (Leske) and E. {Boletid) polyzonalis (Lam.) are also re- 
corded as East-Indian and redescribed by Martens (1. c.). 
Bolsche, having had an opportunity of examining original specimens of 
Garelia cineta (A. Ag.), is of opinion that although Echinothrix petersii (Bols.) 
is, from the structure of its spines, very close to the first-named species, yet 
it can be at once distinguished from it by its four rows of large tubercles, 
almost alike, on the ambulacral space. He does not understand a statement 
of A. Agassiz to the ofl'ect, not only that G. cincta (A. Agass.) is the same as 
E. petersii (Bols.), but that E. turcarum is only a young form of this latter.

Diadema setosa (Rumph.). The only difference that Bolsche could discover, 
after a careful search, between this species and D. antillarum, Philippi, is that 
in the former the whorls on the spines are closer than in the latter. Ibid, 
p. 89. 
Toxopneustes and Boletia. Verrill (1. c. p. 341) discusses the synonymy of 
these genera, both originally established on the same type. He holds that, 
notwithstanding the change made by Agassiz and Desor, Toxopneustes must 
be applied to Boletia (Desor), and proposes the new name of Euryechinus for 
the group of which the true Echinus drohachiensis (Miill.) is the type. 
Martens (1. c.) describes the following new species from Japan : —
