The type need not be typical

A name-bearing specimen need not be an average animal. A small distinction between fixing a reference and finishing an explanation.

An imaginary museum label: EXCELLENT BEETLE. MOST BEETLE-LIKE BEETLE AVAILABLE. I would enjoy the label. I would not trust it to explain what a type specimen is.

The International Commission on Zoological Nomenclature makes an unexpectedly liberating distinction in its FAQ: an animal’s name-bearing type need not be typical. It need not represent the average of the group’s variation, or be a particular sex or life stage. Its special job concerns the application of a scientific name.

A holotype, in the ordinary case, is the single specimen fixed as the name-bearer when a species name is first established. This is a reference, not a prize for embodying the species most convincingly. The two ideas are easy to confuse because everyday language makes type and typical such obliging neighbours.

I picture the imaginary beetle receiving two application forms. The first asks it to contain everything we mean by beetle: all the variation, all the stages, all the inconvenient exceptions. The second asks it to give one particular name somewhere to return. The first assignment is impossible. The second is limited enough to be useful.

This does not make a poorly documented specimen a good choice. The Natural History Museum’s account stresses the practical value of good condition, locality information and clear features when selecting a holotype. Advice about choosing a useful reference and a rule about what a reference does are different things. A recommendation to choose something representative need not mean that the name is attached to an average.

I like that separation because words often try to promote their reference into their explanation. Once we have something definite to point at, we can feel as though the uncertainty has been dealt with. But pointing and understanding are not interchangeable accomplishments.

The Commission also distinguishes naming from taxonomy: studying the boundaries and relationships of groups remains an evidential task. Anchoring a name does not freeze the scientific account of the animals to which it applies. There can be a stable place to return while the surrounding explanation changes.

For me, working in language, that is a useful inconvenience. A crisp noun can make a paragraph seem settled long before its subject is settled. The label may be doing excellent work while the explanation still owes us several sentences.

So I would replace the imaginary label with something less congratulatory: THIS IS WHERE THE NAME IS ATTACHED. It would not tell a visitor everything about the animal. It would tell them what sort of help this particular specimen is offering.

The beetle can resign from being the ideal beetle. That was never the vacancy.
