That werden wir auch die Globiferen aus Pedizellarien hervorge- 
gangen zu denken haben in åhnlicher Weise, wie wir.die Sphåridien 
als modifizierte Stacheln ansehen”. 
Their function is, as it is proved by examination of the organs 
in life and of their histological structure, to secrete mucus, as was 
also evident from Foettinger's studies. In Bronn's "Classen 
und Ordnungen der Tier-Reichs.. Die Seeigel” 1904, p. 1037, the 
statements from Hamann's work quoted are simply repeated, while 
on påge 1315 some additional remarks are made on the observa- 
tions of Dr. I. C. H.de Meijere given in his "Vorlåufige Besehrei- 
bung der neuen, durch die Siboga-Expedition gesammelten Echini- 
den”.  (Tijdschr. Nederl, Dierk. Vereen. Ser. 2, VIII, 1902, p. 16), 
by which it is proved that the "Globiferen” of Centrostevhanus and 
other Diadematids are only transformed ophicephalous pedicellariæ, 
being thus morphologically different from those of Spltærechinus, 
Boletia, etc., which are transformed globiferous pedicellariæ. 
In 1891 Cuénot, in his most valuable memoir "Études morpho- 
logiques sur les Échinodermes” (Arch. de Biol. XI, p. 366) says of 
the "Globiferæ” : "ce sont des pédicellaires dont la partie terminale 
est atrophiée ...….. et dont il ne reste que la tige et les trois 
glandes å mucus”. ; 
I the "Ingolf” Echinoidea I, these organs are mentioned on 
p: 10, 55 and, especially, pp. 169—170, and the name "claviform” 
pedicellariæ used by Foettinger, who first observed them, read- 
opted for those found in the Diadematidæ, while it is maintained 
that this name cannot be used for those found in Sphærechinus, 
since they are morphologically different, as pointed out by de Meijere. 
In his final report on the: "Siboga” Echinoidea de Meijere also 
adopts the name "claviform pedicellariæ” for these organs. In the” 
"Siam-Echinoidea” I, I have recorded the claviform pedicellariæ from 
the species Diadema saxatile (p- 12), Astropyga radiata (p. 19), 
Chætodiadema granulatum (p. 26) Chætødiad. japonicum (p. 29), 
Echinothrix calamaris (p: 31), and Gymnechinus puichellus (p. 115), 
while the claviform pedicellariæ of the Aspidodiadematidæ are dis- 
Cussed at some length on pp. 38—39.
