There are the normal seven cervical vertebrae and sixteen dorsals.

These have low keels on the snout scales, dorsals somewhat larger than the ventrals, and a pink throat fan.

As a rule the number of lumbars is to some extent dependent upon that of the dorsals.

A greater number of dorsals implies a smaller number of lumbars, and of course vice versa.

The inferior set of the most anterior parapodia' much shorter than the dorsals, strongly curved.

The ornaments of the choir consist in dorsals, tapestry, carpets, and cushions.

Labials, dorsals, ventrals, and subcaudals were the most useful scales.

In the Torpedo the body is nearly round, the tail short and fleshy, with two dorsals and a caudal fin.

The dorsals are small and far back, the tail is slender with small fins, all these being characters shared by the rays.

Dorsals, those which begin with the first thoracic rib, and end at the last that is not fused with the ilium.
