Larcopyle weddellium Lazarus et al, 2005

Description - Add description

Remarks. As noted by Benson (1966, p. 265), this species has an internal structure similar to that of Lithelius minor, i.e., four to five closely spaced, concentric, trizonal shells which appear as single or double spirals or as concentric shells, depending upon the orientation of the test. On the other hand, the genus Spongurus is more closely allied with species consisting of closely spaced, concentric ellipsoidal (not trizonal) shells such as Spongocore puella and Spongurus sp. cf. S. elliptica.
