Holotype. — U.S.N.M. No. 14615, from Port Lotten, Kersail, Caro-

This is a very peculiarly ornamented species, and it somewhat re- 

 motely resembles the form described and named by d'Orbigny in his 

 Cuban papers as Quinqueloculina tricarinata. Our species is, how- 

 ever, apparently quite distinct from d'Orbigny's, and enough speci- 

 mens were found at the type locality to show that the characters are 

 fairly constant. It has not occurred, however, at any of the other 

 stations.

 Test somewhat longer than broad in end view, with the angles 

 subacute or rounded, but generally triangular, occasionally with the 

 angles keeled; chambers distinct, somewhat inflated; sutures slightly 

 depressed; wall ornamented with numerous delicate costae which 

 are rather strongly oblique to the periphery of the chamber; aper- 

 ture at the end of a slight neck, rounded with a simple elongate 

 tooth. Length, 0.3-0.5 mm. ; breadth. 0.18-0.25 mm. ; thickness, 0.12- 

 0.2 mm. 



Chapman originally described this species from the lagoon at 

 Funafuti in the Pacific; it has since been recorded from the Ke-
