congeneric with Carter’s Stellettinopsis simplex 
which Sollas (1888) has made the type of 
Asteropus. Asteropus has been used subse- 
quently by Hentschel (1909) and Dendy 
(1905, 1916, 1924); until recently only de 
Laubenfels persisted in the use of Stellettinop- 
sis. He has added three new species, ketostea, 
isis, and kaena . Levi (1961) has described S. 
cherbonnieri. 
Sollas mentioned (1888:201) that Stelletti- 
nopsis corticata Carter, which was designated as 
the type species of the genus Stellettinopsis by 
de Laubenfels (1936), possessed triaenes and 
was, consequently, genetically distinct from S. 
simplex , which lacked triaenes. Sollas then took 
the rather unwarranted action of dropping Stel- 
lettinopsis entirely and erecting a new genus, 
Algol , for 5*. corticata. De Laubenfels is correct 
In regarding Algol Sollas as a synonym of Stel- 
lettinopsis Carter which is doubtfully distinct 
from Ancorina ; he is, however, incorrect in per- 
sisting in the use of the name Stellettinopsis for 
sponges which consistently lack triaenes. 
Stellettinopsis corticata Carter must be placed 
among the Ancorinidae; its possible synonymy 
with Ancorina can be decided only after a re- 
examination of the type specimen.
