For officers of the Staff Corps below the rank of Commodore the stripes for the different ranks are the same as those described for officers of the Line but the star is omitted, the Corps to which the officer belongs being indicated by stripes of colored cloth filling the spaces between the gold stripes, the colors and materials being as follows:

- Pay Corps Officers—White cloth.
- Professors of Mathematics—olive green cloth.
- Naval Constructors—dark violet cloth.

The shoulder marks for Chief Boatswain, Chief Gunner, Chief Machinist, Chief Carpenter, Chief Sailmaker, Chief Pharmacist and Chief Pay Clerk, bear the gold stripes indicating their rank of the same width and position as in the case of other officers of their rank, except that the gold stripe is broken at the center by a section of one-half of an inch embroidered in dark blue silk, and the corps is shown by the insignia as described for each on [page 124] to be worn on the collars of the frock coats. The insignia in each case are placed on the center of the strap above the stripe.
The shoulder marks for Warrant Officers, Boatswains, Gunners, Machinists, Carpenters, Sailmakers, Pharmacists and Pay Clerks, bear the same insignia indicating the corps of the wearer as those for the Chief Boatswains, Chief Gunners, Chief Machinists, Chief Carpenters, Chief Sailmakers, Chief Pharmacists and Chief Pay Clerks, but the gold stripes indicating rank are omitted.

The rank and corps of officers of the Navy is shown upon the gold epaulets worn with special full dress, full dress and evening full dress uniforms by the regular rank and corps insignia placed upon the top of the epaulet. These insignia are the same for the different ranks or grades as those worn on the collars of the blue service coats.
For Officers of the Staff the epaulets have the same insignia for indicating the rank as in the case of the corresponding rank of officers of the Line, but to indicate the particular corps to which the wearer belongs the proper Corps insignia or devices are substituted in the place of the silver foul anchors worn by officers of the Line.
