h MITRA. 



cato ; labio exteruo flexuoso. — Sliort, solid, ventricose, 

 chestnut, whorls rounded, the last ventricose in the middle, 

 contracted below, with two or three spiral grooves. Mr. 

 Hanley has half-a-dozen specimens of this interesting little 

 shell. 



61. nitida (f. 637), A. Adams. — A small shining brown 

 shell resembling the last, but not ventricose. 



62. cornicula (f. 523), Linnceus. — Mr. Hanley (Ips. Linn. 

 Conch.) thinks that the true cornicula of Linn, was a var. of 

 ebenus. As Mr. Reeve, however, adopts the identification by 

 Deshayes, I follow his example. 



63. graja (f. 525), Reeve. — Resembling cornicula, but 

 different in form, aperture more open at the base. 



64. Typha (f. 323), Reeve. 



65. micans (f. 588), Reeve. 



66. tendis (f. 327), Sowerby. — Testa parva, semipellucida, 

 cornea, pyramidata, fascia pallide fulva superne cincta, spira 

 acuminata, aperturam longitudine sequanti ; apertura antice 

 effusa. — Much like M. typha, but more pyramidal. Transpa- 

 rent, horny, very pyramidal, with a light fulvous band on 

 the upper part of the whorls. 



67. austealis (182), Swainson. — Turreted, with dark 

 brown bands and cinnamon-spotted white bands. 



68. nigra (f. 4), Chemnitz as per Reeve, not Quay. — See 

 sp. 54. 



69. polita (f. 98), Reeve. 



70. digna (f. 145), A. Adams. — More attenuated and acu- 

 minated than M. Nigra. Whorls white, bordered with 



spots. 



71. Sohrceteei (f. 529), Deshayes. — The name is applied 

 to a shell figured by Schrceter, and quoted by Lamarck as 

 one example of cornicula. 



72. bulimoides (f. 180), Reeve. 



73. rhodia (f. 213, 302). — A dark, slim species, with an 

 acuminated spire slightly exceeding tho mouth in length.
