Although Gray described several sea-stars from " Swan River " and 
"" Western Australia" as far back as 1840 (Ann. Mag. Nat. Hist. vol. vi. 
Dec. 1840, p. 281) and 1847 (Proc. Zool. See. London, pp. 75-83), almost 
nothing else was published dealing with the echinoderms of that region until 
after the close of the nineteenth century. In 1907, Koehler reported on the 
collection of ophiurans made by Michaelsen and Hartmeyer between Cape 
Naturaliste and Sharks Bay in 1905. (See their 'Die Fauna Slidwest- 
Australiens,' Bd. i. Lief. 4.) There were 28 species in this collection, of 
which only three were new, and most of the others were well-known Indo- 
Pacific species. In 1911, A. H. Clark published his invaluable report on 
the "Recent Crinoids of Australia^' (Mem. Austral. Mus. vol. iv. pp. 703-804) 
and also a report on the collections made by Michaelsen and Hartmeyer 
(Fauna Siidwest-Australiens, Bd. iii. Lief. 13), the two papers giving a 
complete list of Western Australian Crinoids. In 1914, Doderlein reported 
■on the echini brought back by Michaelsen and Hartmeyer (Fauna Siidwest-
