Clavus is a genus of small sea snails, marine gastropod mollusks in the family Drilliidae. [1] [2]
Apart from the general characteristics of the genera in the family Drilliidae, the species in the genus Clavus have a shell with peripheral tubercles, spines or wing-like processes. [3] The aperture is rather large. The outer lip is produced below the sinus. [4]
The shell of Clavus is characterised by the following features:— Flat indefinite fasciole, indicated only by the curve of growth lines. A smooth subulate protoconch. An insinuation of the outer lip, near the base, like that of Strombus. A major sculpture of prominent arched scales on the shoulder, and a minor sculpture of dense, microscopic, waved, spiral striae. [5]
Most species in this genus have a dorsal varix. But this is absent in a few species such as Clavus beckii, Clavus humilis and Clavus pica.
G.W. Tryon correctly preserved the genus for smooth specimens with a short body whorl, long spire, nodulous shoulder, no spiral sculpture, a wide, deep anal sulcus adjacent to the suture and, in the completely adult, a marked subsutural callus on the body. [6]
The species in this genus occur in the Red Sea, In the Indian Ocean off Mozambique; also off Indonesia, New Caledonia, Papua New Guinea, the Philippines, Solomon Islands, Japan and Australia ( New South Wales, Northern Territory, Queensland, Western Australia).
According to the World Register of Marine Species (WoRMS) the following species with valid names are included within the genus Clavus : [7]
The Indo-Pacific Molluscan Database adds the following species with names in current use :
