578 MESSRS. E. HEROIST-ALLEN AND A. EAELAND ON THE 



Miliolid which occurs very generally in the Kerimba dredgings. The species is 

 evidently closely allied to M. linnceana, and passes into it by almost imperceptible 

 gradations in the strength of the costse. The best specimens occur at Stns. 1, 2 «, 

 6, and 7, where it is especially abundant. At Stn. 11 the individuals are nearly all 

 of a coarsely sulcate type very near M. Unnoeana, from which, however, it is 

 distinguishable by the highly polished surface of its test, and its invariably small size. 

 The texture of M. linnceana is invariably matt to rough.

Not widely distributed, but very fine and typical examples occur at several Stns., 

 though not in any numbers. At Stn. 8 a specimen, otherwise typical, was found with 

 a sub-arenaceous investment. D'Orbigny's Model represents a compressed and almost 

 spiroloculine type with two strong marginal carinae and an extra carina on the face of 

 the last chamber ; the neck is produced and the chambers sigmoid in shape. Brady's 

 fig. 17 (FC. 1884, pi. cxiii.) represents a type which is of much more frequent 

 occurrence in tropical gatherings, having long narrow chambers with little curvature, 

 produced tubular neck, and strong to acute marginal and facial carinse. Of the two 

 slides labelled M. ferussacii in the Brady Collection at .Cambridge, one contains the 

 'Challenger' form in different stages of development, the other, from the Seychelles, 

 contains various Miliolids, but no real M. ferussacii referable to either d'Orbigny 's or 

 Brady's types.
