32 MITEA. 



425. lilacina (f. 634), Soiverby. — Testa lilacina, quam 

 If. marmorea magis solida. 



426. maemorea (f. 635, 636), A. Adams. 



427. catenata (f. 657), Swainson. — Fusiform, with a little 

 tubercle at the top of each rib. 



428. eeenus (f. 329, 334, 5, 6), Lamarck.— Fig. 329, re- 

 presents a doubtful shell, which might perhaps be separated 

 from this species with propriety. M. chelonia and M. Kvida, 

 Reeve, are believed to be only varieties. 



429. Kieneei (f. 324), Soiverby. — A specimen of this 

 shell, exactly the counterpart of Kiener's figure given for 

 M. ebenus, has come to hand, and it is a perfectly distinct, 

 turreted species. 



430. angulosa (f. 531, 534, 535), Martini. 



431. mieabilis (f. 629), A. Adams. — The large shell in the 

 British Museum, late Mr. Cuming's, presents a different 

 appearance from either variety of M. angulosa. It is more 

 rounded at the upper angle of the whorls, and the outer lip 

 is pressed inwards in a curve, also the sculpture is more 

 sinuous. It may be a variety, but if so, one of singular 

 beauty. 



432. clatheata (f. 532, 616), Reeve.' — The later figure is 

 that of a young, unformed shell. The lower part of it is 

 of a pink colour. 



433. eugosa (f. 533), Soivcrby.— Tunc. Cat. 



434. Mutabilis (f. 543, 544), Reeve. — The shell is very 

 angular, and the ribs have a backward, sinuated curve. 



435. lucida (f. 541), Reeve. 



436. nodulifeea (f. 530), A. Adams. 



437. modesta (f. 539), Reeve. 



438. cineeacea (f. 494, 495), Reeve. — The whorls are 

 angular, and the ribs at the angle have each a little white
