Cerithiella sigsbeana is a small gastropod of the family Newtoniellidae that reaches only 13 mm (about 0.5 inch). Its elongate shell is adorned with four beaded spiral cords (“ridges”). The specimen is catalogued as Cerithiella cf. sigsbeana in the Museum collection. After a consultation with Dr Mauricio Fernandes (a marine biologist at Federal University of the State of Rio de Janeiro, Brazil, and a specialist of the Newtoniellidae), he suggested that this species could be a variation extreme of C. sigsbeana, with very pronounced beads on the spiral cord; the “cf.” in this case means “compare with”, meaning that further comparisons are needed before we can be sure that our specimens are indeed that species.

The species was named by William H. Dall in 1881 after Admiral Charles D. Sigsbee, who from 1875 to 1878 commanded the U. S. Coast Survey Steamer Blake (the ship that collected the types--shells examined in the original description of the species). The shell in the photos (in three views) was collected off Key West, Florida (in the Gulf of Mexico), by the Research Vessel Pelican (Louisiana Universities Marine Consortium) and donated to the Museum by Dr Emilio García.

Absolutely loving the fast and furious gameplay of Subway Surfers! The soundtrack is so catchy and really pumps me up while I’m sprinting through the rails. It’s awesome how the game constantly adds new cities and exciting locations, each one with unique visuals and backgrounds that make exploring feel fresh. The hoverboards and character customizations let you express your style, which adds a cool personal touch to the experience. Can’t get enough of those epic coin hunts and close calls!
