Under this ttitle an iconographic study of Liguus shells from the 17th-beginning of 20th century just has been published. The first book in which a Neotropical snail, L. virgineus (L., 1758), was illustrated we are aware of was Philippo Buonanni’s Recreatio mentis et oculi. This appeared in 1684.
The illustration of species from this genus is followed through time, with comments on their (current) classification, until the first full-colour photographs in Simpson’s 1920 book “In lower Florida wilds”.
Unfortunately there are some glitches in the text, and the table appears to be in very small print in the hardcopy (but should be more legible in the PDF); the bold print intended for some text in the table has not survived the editorial process. The correct file is given below (link).

Alex Popovkin sent me some photographs of a snail collected by him in the Atlantic Forest, northern littoral of Bahia, Brazil.
Although this might look weird to those who think Streptaxidae always have dentition in the aperture, these pictures mostly resemble Streptaxis costulatus (Pfeiffer, 1852).
The genus Drymaeus seems as an endless variation on the same theme. Tree snails, elongate and simple in form. Hard to differentiate often one from another.
However, one group is becoming more and more noticeable, the ‘blue’ Drymaeus that may be found in the Caribbean and Central America.
Dan Dourson kindly sent me a picture of a live specimen of Drymaeus sulphureus (Pfeiffer, 1857), which is “very bluish under normal illumination”. It was collected in Belize, Toledo District, Blue Creek Cave.
The previous post evidently led to some excitement in Florida… Bill Frank sent the the following message and photos:
“These are the two that I got out of the palm tree yesterday in Twelve Mile Swamp. They are the largest and nicest specimens that I’ve ever found. I guess that it was worth it to have figured out how to retrieve them from 12-15 feet above ground. Obviously since I’m less than six feet tall and my rake is less than that, I had to do some jumping……….“
Keep jumping Bill, these are lovely creatures 🙂
