The test of this striking species, which belongs to the 
group of ZL. dilatata, Michelotti and ZL. insulae-natalis, 
Jones and Chapman, has an undulating disc, which, when 
cut equatorially, gives the appearance of a central disc 
with four or more rays. Schlumberger described his L. 
formosa as a new species, on the supposition that our Z. 
Murrayana had rectangular chambers. This was evidently 
due to a misreading of our original description, where, 
speaking of Orbitoides stellata, we state’ of that species 
that it “‘has rectangular chambers in the median plane and 
consequently belongs to the Discocycline series.’’ How- 
ever, we proceed to say ‘“‘the earlier known species (O. 
stellata) having rectangular chambers in the median plane, 
we have named this form, which has the rounded imbri- 
cated chambers, distinctively as Orbitoides(Lepidocyclina) 
Murrayana.”’ It follows therefore that LZ. formosa drops 
into the synonymy of the above species.
