Megasurcula carpenteriana (Gabb, 1865), also known as Carpenter's turrid,{{Cite web|url=http://www.jaxshells.org/wclive2.htm|title=Live from Western America (Page Three)}} is a species of medium-sized predatory sea snail, a marine gastropod mollusc in the family Pseudomelatomidae, a family previously lumped with others collectively known as turrids.{{cite journal|editor=Bouchet P. |editor2= Rocroi J.-P. |year=2005|title=Classification and nomenclator of gastropod families|journal=Malacologia: International Journal of Malacology|volume=47 |issue=1–2|publisher=ConchBooks|location=Hackenheim, Germany|isbn=3-925919-72-4|issn=0076-2997 |url=http://www.vliz.be/Vmdcdata/imis2/ref.php?refid=78278}} This species occurs in the Eastern Pacific Ocean. The species was named in honor of Philip Pearsall Carpenter.{{cite journal|author=Gabb, W.M. |year=1865|title=Description of new species of marine shells from the coast of California|journal=Proceedings of the California Academy of Sciences|volume=3|issue=3|pages=182–190}}{{cite WoRMS|author=Auffenberg, Kurt|year=2021|db=MolluscaBase|title=Megasurcula carpenteriana (Gabb, 1865) |id=579016|access-date=28 September 2024}}

Description

The shell is small, in the adult stage averaging about {{cvt|62|mm}} in length, against {{cvt|90|to|110|mm}} in length for the fully adult carpenteriana. It is proportionately much heavier, the anal fasciole is more strongly constricted, and the appressed margin of the whorl does not approach as closely to the periphery of the preceding whorl as in that species. The periphery is often marked by a minutely beaded or undulate thread, and is more nearly midway between the sutures on the spire than in carpenteriana. The aperture is shorter than the spire in nearly every case, while the reverse is true of carpenteriana.
