4.— MONAXONIDA (with Tethyad^)- 
<r ■ 
Keller (1) suggests the following alterations in the classification of 
the Monaxouida Oligoceratina. The family llomorhaphidce contains two 
distinct though related families, Renieridca and Ghalinidce. Near the 
latter come the Heterorhaphidce. The Suberilidce are sharply limited, and 
near them should come the Spirastrellidce and also the Placospongidai, 
which are shown to be Clavulina by their pin-shaped spicules, while 
their siliceous spheres have arisen from spi rasters. The Tethyadca should 
be placed near Clavulina as Fseudotctraxonina, and a degenerate branch 
from them are the Ghondrosuhe. The genus Latrunculia should be a 
special family Latrunculidce.
