BOLIVINA CAMPANULATA Egger. 



Bolivina campanulata Egger, Abh. kon. bay, Akad. Wies. Munchen, CI. II, vol. 

 18, 1893, p. 401, pi. 8, figs. 53, 54. 



Among other stations from which Egger describes this minute 

 species is Gazelle Station 3, in 5,301 meters (2,899 fathoms), west of 

 Portugal. 



BOLIVINA COSTATA d'Orbigny. 



Some of the eariier records from the British Isles are given under 

 this name, but it is not recorded by recent writers from this region. 

 Without specimens it is difficult to determine just what was the form 

 referred to.

The only Atlantic record referred to this name is that of Wright 

 given above. He records the species as common at 1,020 fathoms 

 (1,866 meters) off the southwest coast of Ireland. In the material 

 sent me by Mr. Wright I have found specimens which are evidently 

 what he has referred to this name, but they are not like the Pacific 

 material which I have seen, and I doubt very much if they are the 

 same.

Description. — Test much compressed, tapering from the subacute 

 apical end to the apertural end, broadly angular, periphery spinose, espe- 

 cially the later portion; chambers distinct, the outer end of each ex- 

 tended into a short rounded spine; sutures distinct, very slightly 

 depressed, wall smooth, finely punctate; aperture rounded, elongate. 



Length 0.25-0.40 mm. 



Distribution. — This species, as the records show, is very abundant 

 in the region of the British Isles. Except for the record of Sidebottom
