ECHINODEUMATA. 
The Phylogehy of Echinoderms is discussed by Bell (5), CukNOT (1), 
and Neviani, and that of Holothurians by Ludwig (1). 
Under Physiology, the most important observations are those of 
Demoor & Chapeaux on the nervous system, and Durham on the 
wandering cells and their excretory functions. Loeu & Cuenot (1) 
should also be specially cited. Protozoan parasites of Echinoderms are 
described by Cuenot (5), and Mingazzini. 
In the Systematic Literature, the striking feature of the year is the 
large number of works on fossil Echinoids ; see especially Clark, 
Cotteau (l, 3, 4, 5, 6), Gregory (1, 2, 3, 4), de Loriol (3), Seunes & 
Tate, and Hoyle for British liviug Echinoids. Criuoids also are well 
represented: for fossil forms, see Bather (1, 2, 5), de Loriol (3), 
Miller (1, 3), Miller and Gurley, Jaekel (2), and Rowley (1, 
4, 5) ; for living species see Hartlauh & Carpenter (4). Sladen (2) 
has an important memoir on fossil Asterids, and Bell (3, 8) and Perrier 
(4, 5) on recent forms. Walsh describes numerous Holothurians. More 
general systematic works are Sladen (1), and de Loriol (2). 
Finally, attention should be drawn to the progress of Ludwig’s (5) 
most valuable account of Echinodermata ) in which the Holothurians are 
now completed, and also to Perrier’s (3) account of the group in his 
Treatise on Zoology.

The new species appears to connect Thenarocrinus with the Dendro- 
crinites : the type specimen presents some interesting abnormalities.
