At Stn. 11a good many specimens of a handsome Miliolid which appears to be 

 nearer to d'Orbigny's species than to Brady's 31. insignis, which in many points it 

 resembles. D'Orbigny's description in the "Prodrome" (d'O. 1850, etc., PP. vol. ii. 

 p. 409. no. 1369), " espece suborbiculaire, renflee, striee " is scanty but sufficient. 

 The Kerimba specimens are nearly all roughly triangular in section with rounded 

 edges and the surface of the chambers entirely covered with coarse rounded sulci 

 strictly parallel. In a few instances the shell is more compressed and regularly like 

 M. auheriana in outline, but with the same characteristic costse. All the specimens 

 are distinctly quinqueloculine.

Generally distributed, but very rare. The specimens agree much more closely with 

 d'Orbigny's original figure than with those of Goes. Goes states that d'Orbignv's 

 specimen was probably a young shell, but it appears to be a fully developed individual 

 in the d'Orbignyan figure. The Kerimba specimens all diflt'er in certain well-marked 

 features ; the marginal carinse are generally more or less undose, and the surface of 

 the chambers, although usually smooth, is often irregularly and feebly costate. But 

 the most essential point of difl['erence is in the aperture. D'Orbigny states that the 

 aperture is small, round, furnished with a small simple and short tooth. In the 

 Kerimba specimens, however, the aperture is invariably fitted with a flat plate, attached 

 to the penultimate chamber and fitting the aperture like an operculum, leaving only a 

 very narrow slit open round its edge. D'Orbigny's specimens are also described as 

 milky-white, but the Kerimba specimens are dull and matt in texture, the carinal ridges 

 standing out prominently by reason of their whiteness as contrasted with the walls of 

 the chambers.
