to Taylor’s Coscinocyathus aulax, except that Taylor 
describes in the latter species tabulae about 6 mm. apart. 
If these tabulae are definite structures of the normal 
Coscinocyathus-like type, Coscinocyathus aulax would 
fall into our new genus Sigmocoscinus; but if, as we 
rather suspect, the tabulae in Coscinocyathus aulax are 
of spasmodic occurrence and resemble those we have 
just described in Bronchocyathus trachealis, then 
Coscinocyathus aulax will fall into the genus Broncho 
CORRIGENDA.

cyathus, and will be close to or even identical with our 
species sigmoideus. 
Vologdin’s Siberian genus Cyclocyathus may perhaps 
be included in the family Bronchocyathidae. We have 
not read a full description of other details of Cyclo- 
cyathus, but, as far as the inner walls go, the various 
species have considerable resemblance to Bronchocyathus 
sigmoideus.
