SYNONYMS AND EEFERENCES. 



Pupa Poeynna Oebigny, Moll. Cuba, i. 185, pi. xii. figs. 24-26. 

 Cylindrella Pueyana Pfeiffek, Mon. Hel. Viv. ii. 380; iii. 572. 



PoEY Memorias, ii. pi. xii. fig. 10. 

 Cylindrella lactaria Binney, 1. c. in tab. non in textu. 



Remarks. This is the shell figured under the name of 

 lactaria Gould, as remarked in the preceding article. I 

 will here add that this species may readily be distinguished 

 from lactaria by having much rougher strise, and by being 

 entirely free from the "longitudinal, flexuose, milk-white 

 lines " which are the principal characteristic of that spe- 

 cies, and from which, indeed, its name is derived. 



Found in large quantities in Florida ; also in Cuba. 



CYLINDRELLA JEJUNA Gould vol ii. p. 310, pi. Ixix. fig. 3. 



Cylindrella jejuna Pfeiffer, Mon. Hel. Viv. iii. 573. 

 Cylindrella variegata Pfeiffer, Mai. Bl. ii. 13. 



Pfeiffer, in repeating Gould's description, not having 

 seen the shell, suggests its being a variety of C. lactaria. 

 Later (Mai. Blatt. ii. 13) he considers it a synonym of 

 that species, which he refers to his variegata.

Remarks. I have not seen this shell, which was found 

 by Roemer at New Brauenfels, Texas. I have given the 

 original description above, and add an observation from 

 the same source : —
