12 Sfatious. 



Almost universally distributed in one or other of many divergent varieties. Fairly 

 typical forms were observed at many Stns., especially Stns. 1, 2 ^, and 10. At other 

 Stns. the specimens are less typical, and might perhaps be more strictly described as 

 imdose varieties of other recognised species, especially M. Unnceana, M. contoria, and 

 M. ferrnssacii.

A finely striate form with broad and gaping aperture occurs at many of the Stns. 

 which appears to be referable to d'Orbigny's M. undulata, although the majority of the 

 specimens do not exhibit very marked curvature of the chambers. This undulation is 

 however, exhibited strongly at Stn. 9, and in a less degree in occasional specimens 

 from other Stns. The character of the aperture and section of the test seem to 

 suggest the close affinity of the species with M.nussdorfensis (d'O. 1846, FFV. p. 295, 

 pi. xix. figs. 13-15) and M. broiigniartii.

Generally distributed and often plentiful. The bulk of the specimens are of the 

 normal quinqueloculine type as figured by Brady, but more elongate and delicate, being- 

 nearer Karrer's figure. At some of the Stns. other reticulate varieties occur, notably 

 at Stns. 11 and 13, where a broad and angular quinqueloculine type near d'Orbigny's 

 Qainqueloculina affinis occurs (d'O. 1826, TMC. p. 302. no. 41 ; see F. 1902, FLR. p. 23, 

 fig. 17). At Stn. 11 a long and very pretty quinqueloculine form was found with regular 

 markings and suggesting Terquem's Q. pertusa in the neatness and regularity of its 

 reticulations, which he compares to a " trellis of very fine oblique striae, forming regular 

 lozenges " (T. 1882, FEP. p. 183, pi. xx. (xxviii.) fig. 5). At Stn. 11 a very beautiful 

 form occurs, which we figure. It has angular chambers excavate at the periphery and
