ZOOLOGICAL LITERATURE. 
ture of a type of Echinoderm-larva very imperfectly known. 
While there are many important differences between Brachio- 
laria on the one hand, and Tornaria on the other, still the re- 
semblance of the oldest observed stages of the latter to the 
younger stages of tlic former is very striking, and leaves no 
doubt that Tornaria is the larva of a starfish. 
Linckia multiforis (Lam.) and Oreaster muricatus (Linck). Martens {1. c.) 
gives an account of some of the varieties of these two species met with in the 
Indian Archipelago. 
Asterias. Venill (1. c. p. 339) objects to the adoption of Asteracanthion as 
the name of this genus, and remarks that both Uraster and Stellonia have pre- 
cedence if the Linnean name is to be changed. 
Leptasteriasj g. n., Verrill, 1. c. p. 350. Allied to Asterias j papulai compa- 
ratively large, placed singly or in groups of 2 or 3 on the sides and back of 
the rays ; plates usually stout and imbricated ; madreporic plate generally 
suiTounded by a circle of spines. Sp. A. miilleri (Sars), A. compta (Stimps.) ; 
A. (L.) stimpsoni, sp. n., Verr. /. c. p. 349 (= A. miilleri^ Stimps. nee Sars)^ 
New England (Acadian Fauna). 
Martens (/. c.) gives a list of twenty-one species met with by himself in the 
Indian Archipelago. The following are described as new : — 
Linckia pustulatay p. 62, Larentuka, Flores, and Amboyna, related to Ophidi- 
astcr cylindrious (Miill.) ; L. rosenheryi, p. 63, Amboyna ; L. pauciformis^ p. 69, 
Adenare, an island near Flores ; and L. speciostes, p. 70, Larentuka, Flores. 
Asterina coronatay p. 73, Batjan, Amboyna, and Larentuka. 
Gymnastei'ias hiserratay p. 74, Larentuka. 
Goniaster clavatuSy p. 82, Larentuka. 
Grube (/. c.) describes the following new species : — 
Luidia debilis and L. foliolata, p. 35. 
Astropecten o^emV, p. 36; A. diplacanthuSy \yidL. ] A. ensifevy ibid., Fiji 
Islands; A. chinensisy ibid., Hongkong; A. umbrmuSy ibid., Hongkong; and 
A. paleatusy p. 37. 
Ophiuroidea. 
Martens (1. c. p. 87) gives a list of six species of this order met with by 
himself at Amboyna and Timor. 
Trichaster fiagellifei'y sp. n., Martens, 1. c. p. 87, from Singapore and Banka. 
Perhaps = T. pahniferus (Lamk.). 
Echinoiuea. 
Here we would refer to Stewart’s paper (/. e.) on the spicula of the Echi- 
noidea. These spicula vary greatly in the amount of their development in 
different genera and species, and in all probability will be found to afford most 
valuable assistance in determining the limits of both species and genera. 
Spatangoidea. 
Martens records (1. c.) the following as East Indian : — Spatanyus pla- 
nulatus (Lam.), Brissus carinatm (Lam.), B. maeulosus (Leske), B. sternaKs 
(Lam. ?), B. co7npressiis (Lam.). 
Spatanyus {Marctia') varieyatuSy sp. n., Gray, Proc. Zool. Soc. 1866, p. 170, 
from Pulo I’aya, in the China Seas, with a figure. 
Blatybrissus roemeri, sp. n., Grube, I, c. p. 37, native country unknown.
