v, p. 106 (Opeas acutior). Opeas junceum Old., MARTENS,. 

 Sitzungsber. Ges. Naturforsch. Freunde zu Berlin, 1898, p.

 Conch, no. 9, p. 168, 1851 (gardens in Kingston, Jamaica). 



The several names comprised in the above references are 

 absolute synonyms. 8. octonula of which I have two speci- 

 mens from the author, is a typical gracile of the slender phase. 

 One is figured, pi. 28, fig. 71. B. hortensis Ad. of which I 

 have seen Adams' specimens, was based on the stouter form 

 of the species, in which the whorls are less oblique. It is 

 common at Kingston, but so far as I know, not spread over 

 the island. 0. acutius Miller has been from a study of the 

 types pronounced subula by Strebel, a conclusion fully sup- 

 ported by the description and figures. 



I have figured also a rather small specimen, fig. 70, length 

 9 mm., from Havana, the type locality of subula Pfr. 



4. 0. GOODALLI (Miller). PI. 28, figs. 72, 73, 74. 



"A subperf orated, turretted, pellucid, pale corneous, or 

 almost white shell, having from six to seven volutions, and an 

 ovate aperture. 



"Observations. The inhabitant a Umax of a green-yellow- 

 ish 'color, which is transmitted through the shell, and gives it 

 that tinge when found with the animal in it. On account of 

 the pine bed being frequently disturbed, full grown specimens, 

 are rare, and I possess but few that show seven volutions, the 

 major p<art having from four to five. When full grown, one- 

 third of an inch, or rather more, long." (J. S. Miller.)
