Anatomy, Physiology, and Development. 
Preyer (44) has published the first part of a most important and in- 
teresting essay on the movements of Echinoderms: Experiments made 
with an Ophiurid gave evidence of the possession of a power to adapt 
itself to new situations, and appear to justify the application to it of 
the term intelligent ; the curious righting movements are referred to the 
“ muscular sense,’’ just as in the case of the frog : the effects of stimula- 
tion and the extent of irradiation were carefully investigated, and the 
work justifies its title of a “Comparative Physiological-psychological 
Investigation.” The nervous system of Echinus acutus has been investi- 
gated by Prouho (45)', who confirms the results of Loven on the 
peripheral nervous system of Brissojjsis. The innervation of pedicel- 
larim has been studied by Hamann (28.4). 
The vascular system has attracted many workers. Koehler (33) on 
Echinoids generally ; Prouho (46) on Dorocidaris papillata, and (47) 
Spatangus purpureus ; Cuenot (17) on Asteridae, and Koehler, (34) on 
Ophiurids. 
Hamann (28.2) and Beddard [Ann. N. H. (5) xvii, pp. 428-430] treat 
of the striated muscles of Echinoids ; and the former (28.1) describes 
some special glandular organs iu Sphcerechinus granularis , which he calls 
globifers. The Sarasins (52) describes the poison-apparatus of Gyano- 
soma urens , g. & n. sp, which consists of modified spines. 
The development of Comatula has been studied by Barrois (4 & 5), 
and that of Ophiopholis and Echinarachnius by Fowkes(25); Perrier (42) 
mentions a new Asterias — A. hyadesi — in which the young are attached 
to the mother by a prolongation of the buccal membrane.

In a popular account of deep sea Echinoderms, Perrier (41, pp. 
258-287) figures the following new or recently described species : — 
Stephanaster bourgueti , Caulaster pedunculatus ; 
Democrinus parfaiti , Jlyocrinus recuperatus , Eudiocrinus atlanlicus ; 
Eschychropotes buglossa, Siphonothuria incurvata, Ypsilothuria attenuata , 
Y. talismani, and Rliopalodina heurteli.
