maria miniata. The spicules of the two forms are distinetly different 
and since the spicules of Lupwıc’s type-specimens of Cucumaria 
fallax agree perfectly with those of the species I had differentiated 
as new, I shall assume that the internal anatomy also agrees and 
restore the name. Brırren, 1906, fails to discern these differences 
and hence incorreetly identifies the BRASHNIKOW specimens as (ueu- 
maria miniata. CvARrk, 1901, does not give the number of stone- 
canals and if his “scattered pedicels on the interambulacra” means 
on ventral, as well as dorsal, interambulacra, then he erroniously _ 
identifies his specimens as Oucumaria miniata. With more complete 
information on the above points the identity of CLark’s form may 
be determined. The opinion of Lupwiıs, 1881, that SELENKA’s Oueu- 
maria albida is a young example of Oucumaria miniata is undoubtedly 
correct. On the other hand the specimens with “only 1 Polian vessel 
and 1 stone-canal” which CrArK, 1901, refers to Uuceumaria albida 
SELENKA are possibly Cucumaria californica SEMPER. 
Following LAMPERT, 1885, both CLAark, 1902, and EpDwaArDs, 
1907, incorrectly identify specimens as (ucumaria japonica SEMPER, 
which should be known as Cucumaria miniata. These decided con- 
clusions are the result of a prolonged study of a fairly large series 
of specimens and it is my belief that the status of these members 
of the Oucumaria frondosa species-cycle is now more clearly estab- 
lished. 
For the opportunity to investigate the rich collections of the 
United States National Museum I would express my especial thanks. 
to Prof. RıcHarp RATHBUnN, Assistant Secretary of the Smithsonian 
Institution. Also I desire to thank Directors Lexz, of the Lübeck 
Museum, and Nassoxoy, of the Zoological Museum of the Academy 
of Sciences of St. Petersburg, for courtesies extended to me.
