Odostomia carrozzai
Habitat: it lives in the infralittoral zone. We found it into detrital sediments. Distribution: it can be found in several localities of the Mediterranean. Common enough , collected at Krk Is. (Croatia), at 40 m depth.
Notes: this species is characterized by a protoconch type B large in sizes (> 300 micron). Rather variable in outline but generally more stretched than O. eulimoides one (H/L ratio equal to 2.7) from which it is distinguishable also due to smaller sizes and to height of last whorl. Whorls are moderately convex, suture broad. Growth lines prosocline, spiral sculpture missing. Inside its mouth it is visible one small tooth placed internally. Umbilicus just sketched. Measures of adult specimens are variable: on an average they are around 3 mm in height. (See confrontation tables pages 152,153)

DISTINCTIVE FEATURES:
• Shells with a clear tooth on the columella.
• Shell surface smooth or with spiral striature.
• No (spiral) ribs.
• Inside of the outer lip smooth.
• Embryonic whorls of type B, some-what tilted.
• Growthlines clearly prosocline.
• Shells slender
• Shells bigger than 2 mm
• Height/Breadth ratio about 2,1.
• Last whorl 0.6 of the total height.
