Point; Pt. Antonio. 
37. Thysanophora boothiana Pfr. Bluefields; Petersfield ; Man- 
deville; Black River; St. Anns; Mt. Pleasant. (T. authoniana 
C. B. A. seems to be only aslightly larger and solider form of this)- 
38. Thysanophora sincera C. B. A. Port Antonio; St. Anns 
Bay ; Ramble; Gallina Point; Montego Bay; W. of Pt. Antonio. 
(Seems only to be a less strongly ribbed var. of 'T. diminuata).

Bog Walk. (T. ptychodes, according to Adam’s shells in the Natl. 
Museum, is considerably more depressed and sharper keeled than 
this species. All our material, however, of both forms is intermedi- 
ate in form and it is probable that the two run together).
