A large specimen from Aux Cayes, Haiti, is figured. It 

 measures, length 63.5, diam. 25.2, length of aperture 39.5 mm., 

 with 7J whorls, and is the same shell noticed by Bland (I. c.). 

 It is more fusiform than 0. voluta, with a more oblique aper- 

 ture, that of voluta being subvertical; the striation is per- 

 ceptibly coarser, and extends nearly to the base. The aper- 

 ture is shorter, and the outer lip more inflexed and more 

 sinuous, being arched forward in the middle. Under the 

 cuticle it is violaceous reddish, paler and whitish near the 

 gray-margined suture, and white at the base and behind the 

 outer lip. The cuticle is olivaceous-tawny, with occasional 

 darker reddish or olive streaks. 



This large form of flexuosa is apparently what Montfort 

 figured as Polyphemus glans (Conch. Syst., ii, p. 414).

 tenia PFEIFFER (in part), and of some other authors, not 

 Boltenia SAVIGNY, 1828 (Ascidians). 



Shell oleacinoid, covered with a very smooth and very 

 glossy yellowish or greenish-yellow cuticle ; sculpture of lon- 

 gitudinal grooves, which are usually very weak and few. 

 Columella abruptly truncate at base. Type 0. oleacea stram- 

 inea. 



Distribution: Haiti, Cuba, Isle of Pines, New Providence, 

 Bahamas. 



All Haitian species of L&voleacina are described below, 

 since the account of them in Vol. I was very incomplete. 



Several of the small Cuban species are but slightly differ- 

 entiated, and are often hard to determine. The contour of 

 the shell and the comparative length of the aperture undergo 

 remarkable changes with age, as shown in the illustrations of 

 0. cleriei. There seems to be considerable individual varia-
