of Jamaica and Cuba described by d'Orbigny as Q. polygona is a very 

 definite species, as shown by the Montego Bay material. These are 

 very different from the slender elongate species usually assigned to 

 Q. ferussacii. The chambers are clear cut and squarish, as shown in 

 the type figure. 



It occurs at stations 3-6 at Montego Bay and is a much smaller 

 species than Q. ferussacii.

This species, described from Cuba and St. Thomas by d'Orbigny 

 as rare, has been recorded by Schlumberger from the region of Mar- 

 seilles and bv Wiesner from the Adriatic.

It is not common in the Jamaican material, the only station being 

 in 1 fathom (2 meters) at Montego Bay.

In the Jamaican material this species stands out very distinctly, of 

 the form and characters shown in d'Orbigny's figure, which is excel- 

 lent. The species has been allowed to lapse since its description, 

 even Brady, strangely enough, not including it as a synonym under 

 any of the species of the Challenger Report. 



Specimens were obtained at Montego Bay from stations 1, 4, 5, 

 and 6.
