182. Eglisia teicaeinata, Ad, Sf Rve., Voy. 'Samarang,' p. 49, 

 The single example is very imperfect, but possesses two 



anfractual carinas only, on the upper whorls. Turritella lepto- 

 mita, Melv. & Sykes (Proc. Mai. Soc. ii. p. 176, pL xiii. figs. 12, 

 12 a), represents a very nearly allied species from the Andamans, 

 the whorls possessing three to four keels on the upper, four at 

 least on the lowest whorl. So rarely found are these nearly 

 allied Eglisice that the anatomy is practically unknown, but the 

 operculum being scalaroid they have on this account been 

 transferred from the TurritellidsB to the Scalariidae.
