This species is represented by numerous varieties, from the smooth 
eeble form fig. 6 to the strongly costate fig. 7 ; but here, as in most 
other regions, the variety M. eontorta is the most abundant of them 
all, especially the rugose form resembling Q. bidentata d’Orbigny * 
and Q. sclerotica Karrer.f A considerable proportion of the speci- 
mens of the strongly costate variety show a tendency to wildness of 
growth, some of the later chambers deviating from the normal plan of 
aggregation, as in M. separans Brady, and in Triloculina nodosaroides 
Karrer. 
This species and its varieties are common at most of the Stations 
in both Areas. 
Its distribution in the northern hemisphere is very wide, but 
according to Brady, in the southern hemisphere it has only been noted 
at two or three points on the coast of Australia, one of which is Baine 
Island, Torres Strait.

Included in this so-called species are the agglutinate forms of 
M. Ferussacii and M. seminulum. To the former of these belong 
the Quinqueloculina agglutinans and Q. enoplostoma of the Cuba 
Memoir, these having the contour of M. eontorta, which again, when 
it has a rough surface, is the M. sclerotica of Karrer, and this form 
sometimes agglutinates sand-grains, or incorporates them sparingly 
into its shell-substance. The specimens figured by Brady, Balkwill, 
and Wright, Brady, Parker, and Jones, Chapman and Egger, are of 
the seminulum type, as are also some of those figured by Goes, whilst 
others have the form of M. eontorta and M. Cuvieriana.
