CORALS FROM THE MOUNTAIN LIMESTONE. 207 
Mr. Lonsdale the name of Strombodes ; the zoological value of which had been previously 
fixed in a manner quite different by Schweigger and by Goldfuss, and he has at the same 
time given the name of Zozsdaleia to a new division comprising the corals which do not 
differ from his ill-denominated Strombodes by their structure, but are only fasciculate and 
not coalescent. This latter distinction does not appear to us advisable, and in order not to 
augment without necessity the number of generic names applied to the same objects, we 
have employed the name of Zonsdaleia in a wider acceptation, and made it equivalent to 
the Zithostrotion of Mr. Lonsdale, and to Lonsdaleia and Strombodes of Professor M ‘Coy. 
Lonsdaleia floriformis is easily distinguished from Z. rugosa’ and L. duplicata’ by the 
disposition of its corallites to coalesce completely. It differs from Z. Bronni* by the 
unequal development of its septa, and from Z. papillata‘ by its columella bemg larger and 
more prominent, and by the part of the corallites situated near the exterior wall not being 
entirely vesicular.

Corallum massive ; upper end of the corallites polygonal, often tetragonal, with simple, 
thin edges ; exterior zone almost flat; calicinal fossula rather large and deep. Colwmella 
not very prominent, somewhat attenuated upwards, and bearing laterally subvertical, 
oblique, slightly curved ridges. Principal septa 22 or 24 in number, thin, not extending 
quite to the columella, and alternating with an equal number of small ones. Great diagonal 
of the corallites, in general, about 8 lines. Diameter of the walls 33 or 4 lines.

A vertical section shows that the inner walls are slender, but very distinct, and formed 
by the inner edge of the vesicles of the exterior zone, which are somewhat unequal, strongly
