Description

The size of the adult shell varies between 7 mm and 12 mm. The imperforate shell has a conical shape and consists of five whorls. The sutures are impressed in an irregularly way. It is in appearance somewhat similar to Austrocochlea porcata. The minute tubercles at the base of the callous, slightly oblique columella are rather more conspicuous than in that species. The numerous revolving lirae and the three keels are granulose. The convex base of the shell is strongly ridged and brightly spotted. The aperture is subquadrate. It is silvery white on the inside, and has 7 lirae. The peristome is sharp and maculated.[2]

Distribution

This marine shell occurs off the Philippines.

gollark: It also took something like 10% of the time to write, which is good.
gollark: - unbee python- the osmarkspythonbuildsystem™ functions/variables, to the extent that they exist, constitute an "embedded domain specific language"- Python is more featureful than Dale syntax, however- well, mine does it seminonawfully, if you don't mind its complete lack of job throttling
gollark: Via parser combinators, I can define *exactly* what I want and easily parse it, unless it involves left recursion in which case aææææßæææaæææaaaaæææææææ.
gollark: This is why I combinate all my parsers.
gollark: - yes, python, inevitably- python *is* highly questionable DSL- more features, because python- concurrency, which is the future
