It has no spiral arms.
Our galaxy has only one shape it is a lenticular spiral.

Yes, lenticular galaxies are lens-shaped. They will not have spiral arms.
A Lenticular Galaxy is a galaxy that is in between that of a elliptical and a spiral galaxy. They are disc galaxies that have used up all of their interstellar material and therefore have little, if any, star formation. They can be difficult to distinguish between elliptical galaxies if viewed side on. See related links for more information and pictorial representation
The Spindle Galaxy (NGC 5866) is a relatively bright lenticular galaxy in the constellation Draco.It is about 50 million light years from us.See related link for a picture.
There are actually four broad classifications : spiral, elliptical, lenticular and irregular. Spiral galaxies look, basically, like our Milky Way Galaxy, though there are some variations. Ellipticals can look elongated like a football, or almost spherical. Lenticulars are "lens shaped" galaxies. The irregular category covers just about everything else and include galaxies like our neighbors, the Large and Small Magellanic Clouds . (Classifications vary and there are some that have only three types.)
There are various ways of categorising galaxies, often based on Edwin Hubble's work on the shapes galaxies. Classifications often give the four main types of galaxies as: Spiral (including barred spiral), Elliptical, Lenticular and Irregular.
As the name suggests, the barred spiral galaxy has a barred central core.See related link for a pictorial
