450 ME. E. B. NEWTOlSr ON THE 



Cassis sp. indet. (Plate 30. figs. 10, 11.) 



This specimen is an imperfect cast with a general resemblance 

 to G. suhharpceformis, d'Archiac & Haime (Descr. Anim. Eoss. 

 Numm. rinde, ] 854, vol. ii. pi. 31. fig. 6, p. 317), from the Eocene 

 rocks of India ; but difi"ering from that form in being much 

 shorter and broader, in the «o?^-bifurcate character of the vertical 

 ribs, and the presence of some obscure concentric markings on 

 the principal whorl. The aperture is narrowly elliptical and 

 oblique ; spire only slightly elevated. 



Dme^s^'o^s (in millimetres). Length = 27; diameter =27. 



Locality. Gruverchin Kala. Of similar lithological appearance 

 to the specimen of Pyrula cingulata. (Collected by the Eev. C. 

 Labaree.) 



Formation. Miocene (Burdigalian or Aquitanian).

Original diagnosis. — Testa costata transversim sulcata ; plicis 

 longitudinalihus foriiicatis ; Idbio intus sulcata. (Borson.) 



A somewhat water-worn example is all that represents this 

 species. It shows the characteristic longitudinal, elevated and 

 rounded costulations, of which there are about eight on the 

 principal whorl, separated by deep corresponding sulcations ; the 

 transverse sculpture consisting of numerous regular striations. 

 The anterior canal is broken and the spire is incomplete ; other- 

 wise it preserves the fusoid and elongate shape of this form. 



Dimensions (in millimetres). Length=27 ; diameter =15. 



Borson's original example is localised as Piedmont, and belongs 

 to the Tortonian stage of the Miocene, Homes' specimen from 

 the Vienna Basin (Mollersdorf) being of similar horizon. 



Locality. Prom the beach of Koyun Daghi island. 



T'ormation. Miocene (Tortonian) The specimen has a reddish 

 tinge similar to what is present in some of the examples of 

 Alectryonia Virleti, and probably came from the same bed.
