There is a peculiar ragged appearance characteristic of this species. 

 The chambers are not uniformly placed, the sutures more or less open 

 and the costae often toothed and uneven. The species is a fairly 

 common one in the West Indian region.

Test short and broad, periphery broadly rounded or somewhat 

 truncate, the outer side of the chamber with longitudinal costae, the 

 sides almost smooth, with fine striae; aperture not produced, with a 

 somewhat rounded lip and simple tooth. 



Length, 0.60 mm.; breadth, 0.35 mm.; thickness, 0.25 mm. 



Schlumberger has recorded this species from the Mediterranean. 

 It is somewhat near Q. undulata d'Orbigny, but Q. disparilis may be 

 distinguished by the more flattened periphery and the somewhat 

 straight or even concave sides which are finely striate. The figured 

 specimens are from off Plymouth, England. It is related to Q. 

 bicornis (Walker and Jacob). 



QUINQUELOCULINA FERUSSACD d'Orbigny 



This species has been recorded from about the British Isles but 

 the specimens differ somewhat from d'Orbigny 's model which has an 

 elongate neck. Heron-Allen and Earland have recorded it from the 

 North Sea, from about the Shetland Islands, off the coast of Scotland 

 and from the Clare Island region of Ireland. They note that 

 Williamson recorded it under the name Miliolina bicornis, var. 

 angulata. I have not had specimens from the western Atlantic that 

 could be referred to this species.
